could anybody explain to me why the execution plan of the select statement differs completly from the execution plan of the update statement? While the select statement uses a very good plan using nested loops and highly indexed access the update statement full scans the tables accessed through the view v_titel2 ? Please see attached textfiles for execution plans. If more information is needed I could provide 10046 and 10053 traces.
