public classDataTruncationextendsSQLWarning
An exception thrown as aDataTruncation exception (on writes) or reported as aDataTruncation warning (on reads) when a data values is unexpectedly truncated for reasons other than its having exceededMaxFieldSize.

The SQLstate for aDataTruncation during read is01004.

The SQLstate for aDataTruncation during write is22001.

    • DataTruncation

      public DataTruncation(int index, boolean parameter, boolean read, int dataSize, int transferSize)
      Creates aDataTruncation object with the SQLState initialized to 01004 whenread is set totrue and 22001 whenread is set tofalse, the reason set to "Data truncation", the vendor code set to 0, and the other fields set to the given values. Thecause is 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 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

    • DataTruncation

      public DataTruncation(int index, boolean parameter, boolean read, int dataSize, int transferSize,Throwable cause)
      Creates aDataTruncation object with the SQLState initialized to 01004 whenread is set totrue and 22001 whenread is set tofalse, the reason set to "Data truncation", the vendor code set to 0, and the other fields set to the given values.
      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
      cause - the underlying reason for thisDataTruncation (which is saved for later retrieval by thegetCause() method); may be null indicating the cause is non-existent or unknown.

  • Method Details

    • 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 theparameter andread fields 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:
      true if the value truncated was a parameter;false if it was a column value

    • getRead

      public boolean getRead()
      Indicates whether or not the value was truncated on a read.
      Returns:
      true if the value was truncated when read from the database;false if 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-1 if 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-1 if the size is unknown.
      Returns:
      the number of bytes of data actually transferred
