Question

How can i write an sql query to only return rows from a table

where for example column A is not null AND columb B is not 0

the way i am writing it is:

where A is not null AND B !=0 

but the problem is that the query result is also eliminating rows where only one of the conditions is true such as column a being null but column b being anything but 0 & vice versa

I need the query to only eliminate (not return) the rows where BOTH conditions of my where clause are met.

I only want the result i get from query to be rows from the table where column A is not NUll and column B IS NOT = 0 but i need BOTH conditions to be met not just one of them

Answer 1

Someone posted this Answer on here but then they deleted it (not sure why?) but their answer worked and it was.

WHERE NOT(A is null AND B=0)

i tried using

where A is not null AND B <> 0   

and

where (A is not null AND B <> 0) 

but the where clause would be triggered even if only 1 of the conditions was met and I needed it to be triggered only when both conditions where met.

So again, the answer to my questions was using the below code.

WHERE NOT(A is null AND B=0)

Thanks!
