Why no value under EXEC# column in execution plan?

edited Aug 30, 2023 12:09PM in Database Tuning (MOSC) 1 commentAnswered

Whether I hit <F6> to get the autotrace plan of a SQL statement or <F10> to get an Explain plan, the EXEC# column is never populated, it's blank. I turned on execution order so I can see what the actual sequence is of an execution plan, which row sources are executed before others, but that column is blank. Does anyone know why?
