Parameters:   pos - the position in the BLOB object at whichto start writing Parameters:   bytes - the array of bytes to be written to the BLOBvalue that this Blob object represents the number of bytes written exception:   SQLException - if there is an error accessing theBLOB value See Also:   ValueBlob.getBytes since:    1.4 setBytes public int setBytes(long lpos, byte[] bytes, int offset, int len) throws SQLException(Code) Writes all or part of the given byte array to the BLOB value that this Blob object represents and returns the number of bytes written. Writing starts at position pos in the BLOB value; len bytes from the given byte array are written. Parameters:   pos - the position in the BLOB object at whichto start writing Parameters:   bytes - the array of bytes to be written to this BLOBobject Parameters:   offset - the offset into the array bytes at whichto start reading the bytes to be set Parameters:   len - the number of bytes to be written to the BLOBvalue from the array of bytes bytes the number of bytes written exception:   SQLException - if there is an error accessing theBLOB value See Also:   ValueBlob.getBytes since:    1.4 setDatafile public void setDatafile(Datafile file)(Code) setPermBlock public void setPermBlock(long block)(Code) show public String show()(Code) toString public String toString()(Code) truncate public void truncate(long len) throws SQLException(Code) Truncates the BLOB value that this Blob object represents to be len bytes in length. Parameters:   len - the length, in bytes, to which the BLOB valuethat this Blob object represents should be truncated exception:   SQLException - if there is an error accessing theBLOB value. since:
