Constructor Detail

JdbcRowSetImpl

public JdbcRowSetImpl()
Constructs a default JdbcRowSet object. The new instance of JdbcRowSet will serve as a proxy for the ResultSet object it creates, and by so doing, it will make it possible to use the result set as a JavaBeans component.

The following is true of a default JdbcRowSet instance:

A newly created JdbcRowSet object must have its execute method invoked before other public methods are called on it; otherwise, such method calls will cause an exception to be thrown.

Throws:
java.sql.SQLException - [1] if any of its public methods are called prior to calling the execute method; [2] if invalid JDBC driver properties are set or [3] if no connection to a data source exists.

JdbcRowSetImpl

public JdbcRowSetImpl(java.sql.Connection con)
               throws java.sql.SQLException
Constructs a default JdbcRowSet object given a valid Connection object. The new instance of JdbcRowSet will serve as a proxy for the ResultSet object it creates, and by so doing, it will make it possible to use the result set as a JavaBeans component.

Method Detail

initMetaData

protected void initMetaData(javax.sql.RowSetMetaData md,
                            java.sql.ResultSetMetaData rsmd)
                     throws java.sql.SQLException
Initializes the given RowSetMetaData object with the values in the given ResultSetMetaData object.

Parameters:
md - the RowSetMetaData object for this JdbcRowSetImpl object, which will be set with values from rsmd
rsmd - the ResultSetMetaData object from which new values for md will be read
Throws:
java.sql.SQLException - if an error occurs

checkState

protected void checkState()
                   throws java.sql.SQLException
Throws:
java.sql.SQLException

execute

public void execute()
             throws java.sql.SQLException
Creates the internal ResultSet object for which this JdbcRowSet object is a wrapper, effectively making the result set a JavaBeans component.

Certain properties must have been set before this method is called so that it can establish a connection to a database and execute the query that will create the result set. If a DataSource object will be used to create the connection, properties for the data source name, user name, and password must be set. If the DriverManager will be used, the properties for the URL, user name, and password must be set. In either case, the property for the command must be set. If the command has placeholder parameters, those must also be set. This method throws an exception if the required properties are not set.

Other properties have default values that may optionally be set to new values. The execute method will use the value for the command property to create a PreparedStatement object and set its properties (escape processing, maximum field size, maximum number of rows, and query timeout limit) to be those of this rowset.

Specified by:
execute in interface javax.sql.RowSet
Throws:
java.sql.SQLException - if (1) a database access error occurs, (2) any required JDBC properties are not set, or (3) if an invalid connection exists.

setProperties

protected void setProperties(java.sql.PreparedStatement ps)
                      throws java.sql.SQLException
Throws:
java.sql.SQLException

connect

prepare

protected java.sql.PreparedStatement prepare()
                                      throws java.sql.SQLException
Throws:
java.sql.SQLException

next

public boolean next()
             throws java.sql.SQLException
Moves the cursor for this rowset's ResultSet object down one row from its current position. A ResultSet cursor is initially positioned before the first row; the first call to the method next makes the first row the current row; the second call makes the second row the current row, and so on.

If an input stream is open for the current row, a call to the method next will implicitly close it. A ResultSet object's warning chain is cleared when a new row is read.

Specified by:
next in interface java.sql.ResultSet
Returns:
true if the new current row is valid; false if there are no more rows
Throws:
java.sql.SQLException - if a database access error occurs or this rowset does not currently have a valid connection, prepared statement, and result set

close

public void close()
           throws java.sql.SQLException
Releases this rowset's ResultSet object's database and JDBC resources immediately instead of waiting for this to happen when it is automatically closed.

Note: A ResultSet object is automatically closed by the Statement object that generated it when that Statement object is closed, re-executed, or is used to retrieve the next result from a sequence of multiple results. A ResultSet object is also automatically closed when it is garbage collected.

Specified by:
close in interface java.sql.ResultSet
Throws:
java.sql.SQLException - if a database access error occurs

wasNull

public boolean wasNull()
                throws java.sql.SQLException

Specified by:
getBinaryStream in interface java.sql.ResultSet
Parameters:
columnName - the SQL name of the column
Returns:
a Java input stream that delivers the database column value as a stream of uninterpreted bytes; if the value is SQL NULL, the result is null
Throws:
java.sql.SQLException - if (1) a database access error occurs or (2) this rowset does not have a currently valid connection, prepared statement, and result set

getWarnings

public java.sql.SQLWarning getWarnings()
                                throws java.sql.SQLException
Returns the first warning reported by calls on this rowset's ResultSet object. Subsequent warnings on this rowset's ResultSet object will be chained to the SQLWarning object that this method returns.

The warning chain is automatically cleared each time a new row is read.

Note: This warning chain only covers warnings caused by ResultSet methods. Any warning caused by Statement methods (such as reading OUT parameters) will be chained on the Statement object.

Specified by:
getWarnings in interface java.sql.ResultSet
Returns:
the first SQLWarning object reported or null
Throws:
java.sql.SQLException - if (1) a database access error occurs or (2) this rowset does not have a currently valid connection, prepared statement, and result set

clearWarnings

public void clearWarnings()
                   throws java.sql.SQLException
Clears all warnings reported on this rowset's ResultSet object. After this method is called, the method getWarnings returns null until a new warning is reported for this rowset's ResultSet object.

Specified by:
clearWarnings in interface java.sql.ResultSet
Throws:
java.sql.SQLException - if (1) a database access error occurs or (2) this rowset does not have a currently valid connection, prepared statement, and result set

getCursorName

public java.lang.String getCursorName()
                               throws java.sql.SQLException
Gets the name of the SQL cursor used by this rowset's ResultSet object.

In SQL, a result table is retrieved through a cursor that is named. The current row of a result set can be updated or deleted using a positioned update/delete statement that references the cursor name. To insure that the cursor has the proper isolation level to support update, the cursor's select statement should be of the form 'select for update'. If the 'for update' clause is omitted, the positioned updates may fail.

The JDBC API supports this SQL feature by providing the name of the SQL cursor used by a ResultSet object. The current row of a ResultSet object is also the current row of this SQL cursor.

Note: If positioned update is not supported, a SQLException is thrown.

Specified by:
getCursorName in interface java.sql.ResultSet
Returns:
the SQL name for this rowset's ResultSet object's cursor
Throws:
java.sql.SQLException - if (1) a database access error occurs or (2) xthis rowset does not have a currently valid connection, prepared statement, and result set

public java.sql.ResultSetMetaData getMetaData()
                                       throws java.sql.SQLException
Retrieves the number, types and properties of this rowset's ResultSet object's columns.

Specified by:
getMetaData in interface java.sql.ResultSet
Returns:
the description of this rowset's ResultSet object's columns
Throws:
java.sql.SQLException - if (1) a database access error occurs or (2) this rowset does not have a currently valid connection, prepared statement, and result set

getObject

public java.lang.Object getObject(int columnIndex)
                           throws java.sql.SQLException

Gets the value of the designated column in the current row of this rowset's ResultSet object as an Object.

This method will return the value of the given column as a Java object. The type of the Java object will be the default Java object type corresponding to the column's SQL type, following the mapping for built-in types specified in the JDBC specification.

This method may also be used to read datatabase-specific abstract data types. In the JDBC 3.0 API, the behavior of method getObject is extended to materialize data of SQL user-defined types. When a column contains a structured or distinct value, the behavior of this method is as if it were a call to: getObject(columnIndex, this.getStatement().getConnection().getTypeMap()).

Specified by:
getObject in interface java.sql.ResultSet
Parameters:
columnIndex - the first column is 1, the second is 2, and so on

Returns:
true if the cursor is on the last row; false otherwise
Throws:
java.sql.SQLException - if a database access error occurs or this rowset does not currently have a valid connection, prepared statement, and result set

beforeFirst

public void beforeFirst()
                 throws java.sql.SQLException

last

public boolean last()
             throws java.sql.SQLException
Moves the cursor to the last row in this rowset's ResultSet object.

Specified by:
last in interface java.sql.ResultSet
Returns:
true if the cursor is on a valid row; false if there are no rows in the result set

absolute

public boolean absolute(int row)
                 throws java.sql.SQLException
Moves the cursor to the given row number in this rowset's internal ResultSet object.

If the row number is positive, the cursor moves to the given row number with respect to the beginning of the result set. The first row is row 1, the second is row 2, and so on.

If the given row number is negative, the cursor moves to an absolute row position with respect to the end of the result set. For example, calling the method absolute(-1) positions the cursor on the last row, calling the method absolute(-2) moves the cursor to the next-to-last row, and so on.

An attempt to position the cursor beyond the first/last row in the result set leaves the cursor before the first row or after the last row.

Note: Calling absolute(1) is the same as calling first(). Calling absolute(-1) is the same as calling last().

Specified by:
absolute in interface java.sql.ResultSet
Returns:
true if the cursor is on the result set; false otherwise
Throws:
java.sql.SQLException - if (1) a database access error occurs, (2) the row is 0, (3) the result set type is TYPE_FORWARD_ONLY, or (4) this rowset does not currently have a valid connection, prepared statement, and result set

relative

public boolean relative(int rows)
                 throws java.sql.SQLException
Moves the cursor a relative number of rows, either positive or negative. Attempting to move beyond the first/last row in the result set positions the cursor before/after the the first/last row. Calling relative(0) is valid, but does not change the cursor position.

Note: Calling the method relative(1) is different from calling the method next() because is makes sense to call next() when there is no current row, for example, when the cursor is positioned before the first row or after the last row of the result set.

Specified by:
relative in interface java.sql.ResultSet
Returns:
true if the cursor is on a row; false otherwise
Throws:
java.sql.SQLException - if (1) a database access error occurs, (2) there is no current row, (3) the result set type is TYPE_FORWARD_ONLY, or (4) this rowset does not currently have a valid connection, prepared statement, and result set

previous

public boolean previous()
                 throws java.sql.SQLException
Moves the cursor to the previous row in this ResultSet object.

Note: Calling the method previous() is not the same as calling the method relative(-1) because it makes sense to callprevious() when there is no current row.

Specified by:
previous in interface java.sql.ResultSet
Returns:
true if the cursor is on a valid row; false if it is off the result set
Throws:
java.sql.SQLException - if (1) a database access error occurs, (2) the result set type is TYPE_FORWARD_ONLY, or (3) this rowset does not currently have a valid connection, prepared statement, and result set

                  throws java.sql.SQLException
Gives the JDBC driver a hint as to the number of rows that should be fetched from the database when more rows are needed for this ResultSet object. If the fetch size specified is zero, the JDBC driver ignores the value and is free to make its own best guess as to what the fetch size should be. The default value is set by the Statement object that created the result set. The fetch size may be changed at any time.

Specified by:
setFetchSize in interface java.sql.ResultSet
Overrides:
setFetchSize in class BaseRowSet

Specified by:
rowDeleted in interface java.sql.ResultSet
Returns:
true if a row was deleted and deletions are detected; false otherwise
Throws:
java.sql.SQLException - if a database access error occurs or this rowset does not currently have a valid connection, prepared statement, and result set

Updates the underlying database with the new contents of the current row of this rowset's ResultSet object and notifies listeners that a row has changed. This method cannot be called when the cursor is on the insert row.

Specified by:
updateRow in interface java.sql.ResultSet
Throws:
java.sql.SQLException - if (1) a database access error occurs, (2) this method is called when the cursor is on the insert row, (3) the concurrency of the result set is ResultSet.CONCUR_READ_ONLY, or (4) this rowset does not currently have a valid connection, prepared statement, and result set

deleteRow

public void deleteRow()
               throws java.sql.SQLException
Deletes the current row from this rowset's ResultSet object and from the underlying database and also notifies listeners that a row has changed. This method cannot be called when the cursor is on the insert row.

refreshRow

public void refreshRow()
                throws java.sql.SQLException
Refreshes the current row of this rowset's ResultSet object with its most recent value in the database. This method cannot be called when the cursor is on the insert row.

The refreshRow method provides a way for an application to explicitly tell the JDBC driver to refetch a row(s) from the database. An application may want to call refreshRow when caching or prefetching is being done by the JDBC driver to fetch the latest value of a row from the database. The JDBC driver may actually refresh multiple rows at once if the fetch size is greater than one.

All values are refetched subject to the transaction isolation level and cursor sensitivity. If refreshRow is called after calling an updateXXX method, but before calling the method updateRow, then the updates made to the row are lost. Calling the method refreshRow frequently will likely slow performance.

Specified by:
refreshRow in interface java.sql.ResultSet
Throws:
java.sql.SQLException - if (1) a database access error occurs, (2) this method is called when the cursor is on the insert row, or (3) this rowset does not currently have a valid connection, prepared statement, and result set

This method may be called after calling an updateXXX method(s) and before calling the method updateRow to roll back the updates made to a row. If no updates have been made or updateRow has already been called, this method has no effect.

Specified by:
cancelRowUpdates in interface java.sql.ResultSet
Throws:
java.sql.SQLException - if (1) a database access error occurs, (2) this method is called when the cursor is on the insert row, or (3) this rowset does not currently have a valid connection, prepared statement, and result set

moveToInsertRow

public void moveToInsertRow()
                     throws java.sql.SQLException
Moves the cursor to the insert row. The current cursor position is remembered while the cursor is positioned on the insert row. The insert row is a special row associated with an updatable result set. It is essentially a buffer where a new row may be constructed by calling the updateXXX methods prior to inserting the row into the result set. Only the updateXXX, getXXX, and insertRow methods may be called when the cursor is on the insert row. All of the columns in a result set must be given a value each time this method is called before calling insertRow. An updateXXX method must be called before a getXXX method can be called on a column value.

Specified by:
moveToInsertRow in interface java.sql.ResultSet
Throws:
java.sql.SQLException - if (1) a database access error occurs, (2) this rowset's ResultSet object is not updatable, or (3) this rowset does not currently have a valid connection, prepared statement, and result set

setCommand

public void setCommand(java.lang.String command)
                throws java.sql.SQLException
Sets this JdbcRowSet object's command property to the given String object and clears the parameters, if any, that were set for the previous command. In addition, if the command property has previously been set to a non-null value and it is different from the String object supplied, this method sets this JdbcRowSet object's private fields ps and rs to null. (The field ps is its PreparedStatement object, and the field rs is its ResultSet object.)

The command property may not be needed if the RowSet object gets its data from a source that does not support commands, such as a spreadsheet or other tabular file. Thus, this property is optional and may be null.

Specified by:
setCommand in interface javax.sql.RowSet
Overrides:
setCommand in class BaseRowSet
Parameters:
command - a String object containing an SQL query that will be set as this RowSet object's command property; may be null but may not be an empty string
Throws:
java.sql.SQLException - if an empty string is provided as the command value
See Also:
BaseRowSet.getCommand()

setDataSourceName

public void setDataSourceName(java.lang.String dsName)
                       throws java.sql.SQLException
Sets the dataSourceName property for this JdbcRowSet object to the given logical name and sets this JdbcRowSet object's Url property to null. In addition, if the dataSourceName property has previously been set and is different from the one supplied, this method sets this JdbcRowSet object's private fields ps, rs, and conn to null. (The field ps is its PreparedStatement object, the field rs is its ResultSet object, and the field conn is its Connection object.)

The name supplied to this method must have been bound to a DataSource object in a JNDI naming service so that an application can do a lookup using that name to retrieve the DataSource object bound to it. The DataSource object can then be used to establish a connection to the data source it represents.

Users should set either the Url property or the dataSourceName property. If both properties are set, the driver will use the property set most recently.

Specified by:
setDataSourceName in interface javax.sql.RowSet
Overrides:
setDataSourceName in class BaseRowSet
Parameters:
dsName - a String object with the name that can be supplied to a naming service based on JNDI technology to retrieve the DataSource object that can be used to get a connection; may be null
Throws:
java.sql.SQLException - if there is a problem setting the dataSourceName property
See Also:
BaseRowSet.getDataSourceName()

setUrl

public void setUrl(java.lang.String url)
            throws java.sql.SQLException
Sets the Url property for this JdbcRowSet object to the given String object and sets the dataSource name property to null. In addition, if the Url property has previously been set to a non null value and its value is different from the value to be set, this method sets this JdbcRowSet object's private fields ps, rs, and conn to null. (The field ps is its PreparedStatement object, the field rs is its ResultSet object, and the field conn is its Connection object.)

The Url property is a JDBC URL that is used when the connection is created using a JDBC technology-enabled driver ("JDBC driver") and the DriverManager. The correct JDBC URL for the specific driver to be used can be found in the driver documentation. Although there are guidelines for for how a JDBC URL is formed, a driver vendor can specify any String object except one with a length of 0 (an empty string).

Setting the Url property is optional if connections are established using a DataSource object instead of the DriverManager. The driver will use either the URL property or the dataSourceName property to create a connection, whichever was specified most recently. If an application uses a JDBC URL, it must load a JDBC driver that accepts the JDBC URL before it uses the RowSet object to connect to a database. The RowSet object will use the URL internally to create a database connection in order to read or write data.

Specified by:
setUrl in interface javax.sql.RowSet
Overrides:
setUrl in class BaseRowSet
Parameters:
url - a String object that contains the JDBC URL that will be used to establish the connection to a database for this RowSet object; may be null but must not be an empty string
Throws:
java.sql.SQLException - if an error occurs setting the Url property or the parameter supplied is a string with a length of 0 (an empty string)
See Also:
BaseRowSet.getUrl()

setUsername

public void setUsername(java.lang.String uname)
Sets the username property for this JdbcRowSet object to the given user name. Because it is not serialized, the username property is set at run time before calling the method execute. In addition, if the username property is already set with a non-null value and that value is different from the String object to be set, this method sets this JdbcRowSet object's private fields ps, rs, and conn to null. (The field ps is its PreparedStatement object, rs is its ResultSet object, and conn is its Connection object.) Setting these fields to null ensures that only current values will be used.

Specified by:
setUsername in interface javax.sql.RowSet
Overrides:
setUsername in class BaseRowSet
Parameters:
uname - the String object containing the user name that is supplied to the data source to create a connection. It may be null.
See Also:
BaseRowSet.getUsername()

setPassword

public void setPassword(java.lang.String password)
Sets the password property for this JdbcRowSet object to the given String object. Because it is not serialized, the password property is set at run time before calling the method execute. Its default valus is null. In addition, if the password property is already set with a non-null value and that value is different from the one being set, this method sets this JdbcRowSet object's private fields ps, rs, and conn to null. (The field ps is its PreparedStatement object, rs is its ResultSet object, and conn is its Connection object.) Setting these fields to null ensures that only current values will be used.

Specified by:
setPassword in interface javax.sql.RowSet
Overrides:
setPassword in class BaseRowSet
Parameters:
password - the String object that represents the password that must be supplied to the database to create a connection
See Also:
BaseRowSet.getPassword()

                             throws java.sql.SQLException
Sets the transaction isolation property for this JDBC RowSet object to the given constant. The DBMS will use this transaction isolation level for transactions if it can.

For RowSet implementations such as the CachedRowSet that operate in a disconnected environment, the SyncProvider object being used offers complementary locking and data integrity options. The options described below are pertinent only to connected RowSet objects (JdbcRowSet objects).

Specified by:
setTransactionIsolation in interface javax.sql.RowSet
Overrides:
setTransactionIsolation in class BaseRowSet
Parameters:
transIso - one of the following constants, listed in ascending order: Connection.TRANSACTION_NONE, Connection.TRANSACTION_READ_UNCOMMITTED, Connection.TRANSACTION_READ_COMMITTED, Connection.TRANSACTION_REPEATABLE_READ, or Connection.TRANSACTION_SERIALIZABLE
