An exception thrown as a DataTruncation exception (on writes) or reported as a DataTruncation warning (on reads) when a data values is unexpectedly truncated for reasons other than its having execeeded MaxFieldSize.
An exception that reports a DataTruncation warning (on reads) or throws a DataTruncation exception (on writes) when JDBC unexpectedly truncates a data value.
The SQLstate for a DataTruncation
during read
is 01004.
The SQLstate for a DataTruncation during write is 22001.

DataTruncation
public
DataTruncation
(int index,
boolean parameter,
boolean read,
int dataSize,
int transferSize,
String
sqlState)
-
Creates a DataTruncation object with the SQLState initialized to the param sqlState, the reason set to "Data truncation", the vendor code set to 0, and the other fields set to the given values. The cause is not initialized, and may subsequently be initialized by a call to the
Throwable.initCause(java.lang.Throwable)
method.
-
Parameters:
-
index - The index of the parameter or column value
-
parameter - true if a parameter value was truncated
-
read - true if a read was truncated
-
dataSize - the original size of the data
-
transferSize - the size after truncation
-
sqlState - the state indicating read or write truncation
DataTruncation
public DataTruncation(int index,
boolean parameter,
boolean read,
int dataSize,
int transferSize)
-
Creates a DataTruncation object with the SQLState initialized to
01004 when read is set to true and 22001 when read is set to false,
01004,
the reason set to "Data truncation", the
vendor code
vendorCode
set to
0,
the SQLException default,
and the other fields set to the given values.
The cause is not initialized, and may subsequently be initialized by a call to the
Throwable.initCause(java.lang.Throwable)
method.
-
Parameters:
-
index - The index of the parameter or column value
-
parameter - true if a parameter value was truncated
-
read - true if a read was truncated
-
dataSize - the original size of the data
-
transferSize - the size after truncation

cause)
-
Creates a DataTruncation object with the reason set to "Data truncation", the vendor code set to 0, and the other fields set to the given values.
-
Parameters:
-
index - The index of the parameter or column value
-
parameter - true if a parameter value was truncated
-
read - true if a read was truncated
-
dataSize - the original size of the data
-
transferSize - the size after truncation
-
sqlState - the state indicating read or write truncation
-
cause - the underlying reason for this DataTruncation (which is saved for later retrieval by the getCause() method); may be null indicating the cause is non-existent or unknown.

-
Parameters:
-

-
parameter - true if a parameter value was truncated
-
read - true if a read was truncated

getIndex
public int getIndex()
-
Retrieves the index of the column or parameter that was truncated.
This may be -1 if the column or parameter index is unknown, in which case the parameter and read fields should be ignored.
-
-
Returns:
-
the index of the truncated paramter or column value
getParameter
public boolean getParameter()
-
Indicates whether the value truncated was a parameter value or a column value.
-
-
Returns:
-
true if the value truncated was a parameter; false if it was a column value
getRead
public boolean getRead()
-
Indicates whether or not the value was truncated on a read.
-
-
Returns:
-
true if the value was truncated when read from the database; false if the data was truncated on a write
getDataSize
public int getDataSize()
-
Gets the number of bytes of data that should have been transferred. This number may be approximate if data conversions were being performed. The value may be -1 if the size is unknown.
-
-
Returns:
-
the number of bytes of data that should have been transferred
getTransferSize
public int getTransferSize()
-
Gets the number of bytes of data actually transferred. The value may be -1 if the size is unknown.
-
-
Returns:
-
the number of bytes of data actually transferred
getSQLState
public
String
getSQLState
()
-
Retrieves the SQLState for this SQLException object.
-
-
Overrides:
-
getSQLState
in class
SQLException
-
-
Returns:
-
the sqlState value
