SQL_SET_LOB_UC

Applies to: ORAFlex SQLFlex MYSQLFlex PGFlex DB2Flex

This command replaces whatever is currently in a LOB Field with the uChar[] passed. It writes to a client side buffer. It can be used to Write an arbitrary amount of data into a LOB. If passed an empty uChar[], it will remove all the contents of the LOB. If you wish to Set a LOB back to NULL, please use the SQL_SET_LOB_NULL command. NOTE: Unlike the previous call LOB_WRITE, this call does not perform the Save. This must be done separately.
