How to use clause (where,and not,or not) if I have condition like this
I want to show table1.coloumn1='m' and ( table1.colomn2-table2.coloumn2 and table1.coloumn3-table2.coloumn ) if they are not have values same. Is use and, not , combine or,and?
Just write
select table1.*, table2.*
from table1
join table2 on table1.coloumn1='m' and table1.coloumn2<>table2.coloumn2 and table1.coloumn3 <> table2.coloumn3
As you did not write very clearly how you want to combine those conditions with the :
SELECT *
FROM table1, table2
WHERE table1.column1='m'
AND NOT table1.column2 != table2.column2
OR NOT table1.column3 != table2.column3
