>I have a situation that I have been trying to resolve but was unable to up until now. I have a one to many relationships in a SQL where I need to use a condition on the INNER JOIN table. So, for example, the INNER JOIN table might have three records related to one record from the master table in the SQL. But, I need to assure to take only master records where all the INNER JOIN records for that table would satisfy a condition. What could be an example of such a query?
Try
SELECT *
FROM master m
WHERE EXISTS ( SELECT 1 FROM slave s
WHERE s.fk = m.pk HAVING COUNT(*) = SUM( CASE WHEN <condition> THEN 1 ELSE 0 END ))
