DataTruncation

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

Creates the DataTruncation object. The reason is set to "Data truncation", the error code is set to the SQLException default value, and the other fields are set to the values supplied as arguments.

Parameters:

index - the Index value of the column value or parameter that was truncated.

parameter - true if it was a parameter value that was truncated, false otherwise.

read - true if the truncation occurred on a read operation, false otherwise.

dataSize - the original size of the truncated data.

transferSize - the size of the data after truncation.

DataTruncation

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

Creates a DataTruncation. The Reason is set to "Data truncation", the error code is set to the SQLException default value and other fields are set to the values supplied on this method.

Parameters:

index - the Index value of the column value or parameter that was truncated

parameter - true if it was a Parameter value that was truncated, false otherwise

read - true if the truncation occurred on a read operation, false otherwise

dataSize - the original size of the truncated data

transferSize - the size of the data after truncation

cause - the root reason for this DataTruncation

Method Details

getDataSize

public int getDataSize()

Gets the number of bytes of data that should have been read/written.

Returns:

the number of bytes that should have been read or written. The value is set to -1 if the size is unknown.

getIndex

public int getIndex()

Gets the index of the column or of the parameter that was truncated.

Returns:

the index number of the column or of the parameter.

getParameter

public boolean getParameter()

Gets whether the value truncated was a parameter value or a column value.

Returns:

true if the value truncated was a parameter value, false if it was a column value.

getRead

public boolean getRead()

Gets whether the value was truncated on a read operation or a write operation

Returns:

true if the value was truncated on a read operation, false otherwise.

getTransferSize

public int getTransferSize()

Gets the number of bytes of data that was actually read or written.

Returns:

the number of bytes actually read/written. The value may be set to -1 if the size is unknown.
