DataTruncation

public class DataTruncation extends SQLWarning

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.

The SQLstate for a DataTruncation during read is 01004.

The SQLstate for a DataTruncation during write is 22001.

Public Constructor Summary

	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`, the reason set to "Data truncation", the vendor code set to 0, and the other fields set to the given values.

Public Constructors

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, 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

public DataTruncation (int index, boolean parameter, boolean read, int dataSize, int transferSize, Throwable cause)

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	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.

Public Methods

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

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

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

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

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
