Gets the BLOB data as an array of bytes.

Syntax

  
public byte[] getBytes(long pos,  
                       int length)

Parameters

pos

The starting position, starting at 1 (not 0).

length

The length of the data to get.

Return Value

A byte array containing the requested data.

Exceptions

SQLServerException

Remarks

This getBytes method is specified by the getBytes method in the java.sql.Blob interface.

If you have a null or zero length BLOB, and try to get exactly zero bytes at position 1, an empty byte array is returned (byte array of length 0).

If you have a null or zero length BLOB, and try to get any length of bytes at a position other than 1, a position exception will be thrown.
