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

Question

When I'm try to drop the table then I'm getting an 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.

Can someone please help me with this?

Answer 1

I saw the problem in the line below.

exact fetch returns more than requested number of rows

As a result, Oracle received more rows than it had anticipated. Only dual tables have the property, which only produces one row. Later, I remember making a few adjustments to the dual table and running the dual table. Then discovered several rows.

I only inserted the entry with the value X after trimming the dual table. And everything is running smoothly. 

I hope this helps you.
