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 thisDataTruncation
(which is saved for later retrieval by thegetCause()
method); may be null indicating the cause is non-existent or unknown. - Since:
- 1.6
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
