I want to ask if it is possible to make the following statement:
SELCET * FROM WHERE xyz AND wer OR mnb
So generally I want to have if xyz and wer are true it takes these and otherwise it takes the mnb after the OR part. I hope I made somehow clear what I mean?
Further I wanted to ask I gonna have a table with two ID's, both primary keys like
1 2 1 3 1 4 2 2 2 3
This table might have about 60.000-70.000 entries, is that possible or are there constraints regarding waiting time?
thks for the help...
