I have 15 saved queries that filter data from a master table. They just filter out different values (Location Code ie, LAX, NYC, CHI etc).
My problem is that the SQL statements of those queries occasionally get changed to just SELECT;
When I re-enter the SQL and save, it will be fine again. But later it may get changed again back to just SELECT;
The problem is intermittent and does not affect the same query every time. I can't pinpoint why this is happening.
So my question is how does this happen and how can I prevent it?
