Anand, When I do an explain plan on your query (logged in as sys), I see all the stats (on 10.2.0.2) On 2/5/07, Anand Rao <panandrao@xxxxxxxxx> wrote:
Hi, just to add that even if i query without the recyclebin, the problem exists. SELECT NVL2(partition_name, segment_name || ':' || partition_name, segment_name) FROM user_segments WHERE segment_type IN ('TABLE', 'TABLE PARTITION') AND segment_name NOT IN (:p1,:p2,:p3,:p4,:p5) Also, bind variables or not, its the same result. thanks anand On 05/02/07, Anand Rao <panandrao@xxxxxxxxx> wrote: > > Folks, > > Has anyone come across this issue where, > > you run a simple query on dba_segments (or user_segments) and produce a > 10053 trace.
