When I run an explain plan on any query in the Toad Editor, the follwowing error message is displayed:
"ORA-00905 missing keyword"
The schema which your explain plan resides has the underscore symbol but a dash is used instead (or vise versa) when you defined your explain plan in the Toad Options.
For example, you have QUEST-SCHEMA but it is actually QUEST_SCHEMA.
RESOLUTION:
1. Go to View | Toad Options
2. Expand Oracle | General
3. On the right-hand-side, check the Explain Plan section to make sure you did not use a hyphen for an underscore (or vise versa) for the explain plan schema
For example, you QUEST-SCHEMA but it is actually QUEST_SCHEMA
