Hi,
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.
