public class DataTruncation
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 DataTruncation(int index, boolean parameter, boolean read, int dataSize, int transferSize)
DataTruncation
object
with the SQLState initialized
to 01004 when read
is set to true
and 22001
when read
is set to false

The cause
is not initialized, and may subsequently be
initialized by a call to the
Throwable.initCause(java.lang.Throwable)
method.

This may be -1 if the column or parameter index is unknown, in
which case the parameter
and read
fields should be ignored.

true
if the value was truncated when read from
the database; false
