Hello, I just put myself in a weird situation, and I was hoping someone could suggest something about it. I had a query that ran acceptably in 4:52. Explain plan showed: Cost- 32330, Bytes- 590, Cardinality- 5 I then had to insert a line that used the LIKE function for string comparison on a PK field in order to obtain a subset of those values. The explain plan then showed: Cost- 23916, Bytes- 118, Cardinality- 1. However, despite all the values lowering, implying a faster run, it still hadn't completed at over 10:00..... Is that to be expected? Any way to improve this back? Just live with all the values and filter in Excel afterward?
