public class DataTruncation
extends SQLWarning

When JDBC unexpectedly truncates a data value, it reports a DataTruncation warning (on reads) or throws a DataTruncation exception (on writes).

The SQLstate for a DataTruncation is "01004".

DataTruncation(int, boolean, boolean, int, int): Create a DataTruncation object.

getDataSize(): Get the number of bytes of data that should have been transferred.
getIndex(): Get the index of the column or parameter that was truncated.
getParameter(): Is this a truncated parameter value?
getRead(): Was this a read truncation?
getTransferSize(): Get the number of bytes of data actually transferred.

DataTruncation


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

Create a DataTruncation object. The SQLState is initialized to 01004, the reason is set to "Data truncation" and the vendorCode is set to the SQLException default.

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

getIndex


 public int getIndex()

Get 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()

Is this a truncated parameter value?

Returns:: True if the value was a parameter; false if it was a column value.

getRead


 public boolean getRead()

Was this a read truncation?

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()

Get 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()

Get 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
