Java compact2, compact3 java.sql Class DataTruncation（JDK8）

Constructor Detail

• DataTruncation

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

  Creates a DataTruncation object with the SQLState initialized to 01004 when read is set to true and 22001 when read is set to false, the reason set to "Data truncation", the vendor code set to 0, and the other fields set to the given values. The cause is not initialized, and may subsequently be initialized by a call to the Throwable.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 a DataTruncation object with the SQLState initialized to 01004 when read is set to true and 22001 when read is set to false, 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 this DataTruncation (which is saved for later retrieval by the getCause() method); may be null indicating the cause is non-existent or unknown.

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 parameter and read 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
