RA-20001: Unable to drop table STAGE1: does not appear to be a statistics

Hi,

11.2 database, I'm trying to drop a statistics table

SQL>  exec DBMS_STATS.DROP_STAT_TABLE ('SYSADM','stage1');

BEGIN DBMS_STATS.DROP_STAT_TABLE ('SYSADM','stage1'); END;

*

ERROR at line 1:

ORA-20001: Unable to drop table STAGE1: does not appear to be a statistics table

ORA-06512: at "SYS.DBMS_STATS", line 12457

ORA-06512: at line 1

I'm positive stage1 is a statistic table that I created using DBMS_STATS.CREATE_STAT_TABLE. Case is not the problem. I tried uppercase and lowercase table name, I got same error message.

Have anyone had this problem? And how did you solve it?

thanks
