How to solve : SQL Error: ORA-00604: error occurred at recursive SQL level 1

Question

When I'm trying to drop table then I'm getting error

SQL Error: ORA-00604: error occurred at recursive SQL level 2
ORA-01422: exact fetch returns more than requested number of rows
00604. 00000 -  "error occurred at recursive SQL level %s"
*Cause:    An error occurred while processing a recursive SQL statement
           (a statement applying to internal dictionary tables).
*Action:   If the situation described in the next error on the stack
           can be corrected, do so; otherwise contact Oracle Support.

Answer 1

One possible explanation is a database trigger that fires for each DROP TABLE statement. To find the trigger, query the _TRIGGERS dictionary views:

select * from all_triggers
where trigger_type in ('AFTER EVENT', 'BEFORE EVENT')

disable any suspicious trigger with

   alter trigger <trigger_name> disable;

and try re-running your DROP TABLE statement
