public class DataTruncation extends SQLWarning
An exception thrown as aDataTruncationexception (on writes) or reported as aDataTruncationwarning (on reads) when a data values is unexpectedly truncated for reasons other than its having exceededMaxFieldSize.The SQLstate for a
DataTruncationduring read is01004.The SQLstate for a
DataTruncationduring write is22001.- Since:

DataTruncation
public DataTruncation(int index, boolean parameter, boolean read, int dataSize, int transferSize)Creates aDataTruncationobject with the SQLState initialized to 01004 whenreadis set totrueand 22001 whenreadis set tofalse, the reason set to "Data truncation", the vendor code set to 0, and the other fields set to the given values. Thecauseis not initialized, and may subsequently be initialized by a call to theThrowable.initCause(java.lang.Throwable)method.- Parameters:
index- The index of the parameter or column valueparameter- true if a parameter value was truncatedread- true if a read was truncateddataSize- the original size of the datatransferSize- the size after truncation

Method Detail
-
getIndex
public int getIndex()
Retrieves 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
parameterandreadfields should be ignored.- Returns:
- the index of the truncated parameter or column value
-
getParameter
public boolean getParameter()
Indicates whether the value truncated was a parameter value or a column value.- Returns:
trueif the value truncated was a parameter;falseif it was a column value
-
getRead
public boolean getRead()
Indicates whether or not the value was truncated on a read.- Returns:
trueif the value was truncated when read from the database;falseif the data was truncated on a write
-
getDataSize
public int getDataSize()
Gets 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-1if the size is unknown.- Returns:
- the number of bytes of data that should have been transferred
-
getTransferSize
public int getTransferSize()
Gets the number of bytes of data actually transferred. The value may be-1if the size is unknown.- Returns:
- the number of bytes of data actually transferred
