Interface PgqlResultSet

All Superinterfaces:

java.lang.AutoCloseable, java.lang.Iterable<oracle.pgql.lang.ResultAccess>, oracle.pgql.lang.ResultAccess, oracle.pgql.lang.ResultSet<oracle.pgql.lang.ResultAccess>

All Known Implementing Classes:

PgqlResultSetImpl, PgSchemaResultSet, PgViewResultSet

public interface PgqlResultSet
extends oracle.pgql.lang.ResultSet<oracle.pgql.lang.ResultAccess>

This interface provides a ResultSet for a PGQL query execution. It extends the oracle.pgql.lang.ResultSet interface with methods to get meta data for the result set and also to determine the data type for a particular value.

Method Summary

Modifier and Type	Method and Description
void	close() Closes the underlying JDBC ResultSet and Statement.
int	getValueType(int elementIdx) Returns the type of value for the given element.
int	getValueType(java.lang.String elementName) Returns the type of value for the given element.
PgqlResultSet	print() Prints all results to System.out.
default PgqlResultSet	print(long numResults) Prints numResults results to System.out.
default PgqlResultSet	print(long numResults, int from) Prints numResults results from fromth result to System.out.
PgqlResultSet	print(java.io.PrintStream printStream, long numResults, int from) Same as print(long, int) except that this method prints content to printStream.

Method Detail

close

void close()
    throws oracle.pgql.lang.PgqlException

Closes the underlying JDBC ResultSet and Statement.

Specified by:

close in interface java.lang.AutoCloseable

Specified by:

close in interface oracle.pgql.lang.ResultSet<oracle.pgql.lang.ResultAccess>

Throws:

oracle.pgql.lang.PgqlException

getValueType

int getValueType(int elementIdx)
          throws oracle.pgql.lang.PgqlException

Returns the type of value for the given element. The returned values correspond to values in the T column of the PG relational schema.

Parameters:

elementIdx - element index

Returns:

the type of value

Throws:

oracle.pgql.lang.PgqlException - when an error occurs while retrieving the value type

getValueType

int getValueType(java.lang.String elementName)
          throws oracle.pgql.lang.PgqlException

Returns the type of value for the given element. The returned values correspond to values in the T column of the PG relational schema.

Parameters:

elementName - element name

Returns:

the type of value

Throws:

oracle.pgql.lang.PgqlException - when an error occurs while retrieving the value type

print

PgqlResultSet print()

Prints all results to System.out.

Returns:

PgqlResultSet

print

default PgqlResultSet print(long numResults)

Prints numResults results to System.out. If numResults is larger than the number of available results, only the number of available results are printed.

Parameters:

numResults - number of results

Returns:

PgqlResultSet

print

default PgqlResultSet print(long numResults,
                            int from)

Prints numResults results from fromth result to System.out.

Parameters:

numResults - number of results

from - first result to be printed (start counting from 0)

Returns:

PgqlResultSet

print

PgqlResultSet print(java.io.PrintStream printStream,
                    long numResults,
                    int from)

Same as print(long, int) except that this method prints content to printStream.

Parameters:

printStream - stream to which results are printed

numResults - number of results

from - first result to be printed (start counting from 0)

Returns:

PgqlResultSet
