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".

Constructor Index

o DataTruncation(int, boolean, boolean, int, int)

Create a DataTruncation object.

Method Index

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

Constructors

o 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

Methods

o 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.
o 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.
o 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.
o 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
o 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
