SELECT SUM() finds wrong records. I re-built index Com_Inv earlier today by deleting it first.

Use data that you can visualize clearly. Using live data that exhibits a problem is much harder to diagnose than a small sample that exhibits the same problem.

This is, in my mind, exactly the root to many of Naomi's problems. I told her to add structural indexes a long time ago, but this was "not possible". My guess is, considering all her problems, that she should "take the costs", shut the system down the necessary minutes, and add the structural indexes. That would remove more or less all her problems in a few minutes. After the structural indexes are created, she can remove the unnecessary clauses which refers to her IDXs from her code, one by one, without any effect on her program.

Now she is so busy adding band aid all over, which takes her focus away from the real cause for her problems.
