Hi,

So a developer asks me "How do I prevent ORA-1403 in my SELECT statement in my trigger?" I thought this would be simple, but my brain's just not all here.

The statement is simple:

        SELECT description INTO v_desc
        FROM    mytable
        WHERE   indexcol1 = :v_col1
                AND indexcol2 = :v_col2

The problem is that we don't know if the user-entered "indexcol"s exist. I could preface this statement with a "SELECT count(*) INTO mycount..." to see if there are existing rows, but I was hoping to do this all in one SQL statement if possible, especially if/when this scenarios will happen with non-indexed columns (don't ask).

Anyone?

TIA!
