| I've tried the above and it works. Thank you very much, for your help. | |
| Can anyone explain what happened here? Why the Select worked as it was but the Update needed changing to the above? | |
I would have expected the SELECT to work the same as the UPDATE (i.e. to fail with the error). I suspect that in the SELECT, the optimizer is
re-ordering the conditions as someone else stated, and that this allowed the SELECT to work.
