Question

I have this Oracle SQL query which I use to make checks for number:

SELECT * from MANAGEDSYSTEMGROUPS where MSYSTEMGROUPID = ?

I want to select all values different than the value 12. How I must edit the query?

Answer 1

Are you trying to return values that are not set at all?

SELECT * from MANAGEDSYSTEMGROUPS where MSYSTEMGROUPID != 12

Will only return values that have MSYSTEMGROUPID set to a value.

If you want Both values not equal to 12 and values that are not set at all, use this:

SELECT * from MANAGEDSYSTEMGROUPS where MSYSTEMGROUPID  IS NULL OR MSYSTEMGROUPID != 12
