The ones I’ve used (mainly Microsoft sql server) are not just bad, they’re abysmally bad for any query that’s not extremely trivial. Writing every query with explicit joins is a necessity almost 100% of the time. Maybe you’ve just never tried to do anything tricky with large tables with a lot of data? Query optimizers almost always resort to nested table scans as soon as you do anything even slightly complex. |
