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.

 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

 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.

 public boolean getParameter()

Is this a truncated parameter value?

Returns:

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

 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.

 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

 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
