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.

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

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

    method getIndex() returns int public     

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.

    method getParameter() returns boolean public     

Is this a truncated parameter value?

Returns:

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

    method getRead() returns boolean public     

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.

    method getDataSize() returns int public     

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

    method getTransferSize() returns int public     

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
