Hello, We are working to optimize a few queries. When we run the query with Explain, it appears that the query optimizer is not using one of the tables index and doing a full table scan while it appears to use other tables' indices properly. We then remove the table with the full scan, run again with Explain and now the optimizer seems to ignore the index of one of the other tables when it correctly used that table's index before in the previous run. Anyone have some good insight into how the optimizer picks it's query plan? It seems to pick one table and ignore the index for some reason.
