java.lang.Object
- java.lang.Throwable
- - java.lang.Exception
  - - java.sql.SQLException
    - - java.sql.SQLWarning
      - java.sql.DataTruncation

All Implemented Interfaces:

Serializable, Iterable<Throwable>
```
public class DataTruncation
extends SQLWarning
```
An exception thrown as a DataTruncation exception (on writes) or reported as a DataTruncation warning (on reads) when a data values is unexpectedly truncated for reasons other than its having exceeded MaxFieldSize.
The SQLstate for a DataTruncation during read is 01004.

The SQLstate for a DataTruncation during write is 22001.

Since:

1.1

Constructor	Description
`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.
`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.

  - 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
