free

public void free()

This method frees the Blob object and releases the resources that it holds. The object is invalid once the free method is called.

After free has been called, any attempt to invoke a method other than free will result in a SQLException being thrown. If free is called multiple times, the subsequent calls to free are treated as a no-op.

isEmptyLob

public boolean isEmptyLob()

getBytes

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

Throws:

SQLException
