Question

SELECT l.name 
FROM locations as l 
WHERE
    l.location_id =',2,32,'

the “,2,32,” values we get from another table. This query gives zero result, although there are values with location_id=2 and also for 32. Please help me how to use “,2,32,” to get result?

Answer 1

Assuming that you want to return values for ID 2 and 32 you can use this query:

SELECT l.name FROM locations AS l WHERE l.location_id IN (2, 32);

IN operator allows you to specify multiple-values in the WHERE clause

You can also use NOT IN to eliminate certail ID’s and you can also add more id’s to it just by separating them with a comma..
