I enter a sql statement in the code editor and click the ‘explain plan’ icon in the toolbar.
That gives “Error in SQL: ORA-00942: table or view does not exist”
and an option to ‘create table’, with a default name of ‘SQLN_EXPLAIN_PLAN’ under my schema.
I select to create the table.
It returns “Table “SQLN_EXPLAIN_PLAN” already exists.”
Well, it seems we have a real mystery, probably unsolvable at this point. When I tried to reproduce the problem to get some screen shots, it never complained and gave me my explain plan. So I connected to another database that I new I had never use SQL Nav on and tried to reproduce. It merely prompted me to create a plan table, optionally a public synonym, created the table and gave me my explain plan. Looks like we’ll just have to put this aside for now and I’ll keep very close track of what I do in this regard in the future.
