Question

I’m trying to create a query that will only add AND clauses where certain conditions are met.

This is what I’m after:

SELECT DISTINCT
  id
  name
  active
FROM team
WHERE id = 1234
IF team.active = 'y'
  AND team.id IN
    {
       query
    }
ELSEIF team.active = 'n'
  AND team.id IN
    {
      query
    }

But I’m not sure how to do this in SQL. Any suggestions?

Answer 1

 SELECT DISTINCT
    id
    name
    active
    FROM team
 WHERE id = 1234
   AND (team.active = 'y'
     AND team.id IN
        {
          query
        }) 
   OR
    (team.active = 'n'
     AND team.id IN
      {
        query
      })

You use the AND and OR connectives to create the logic.
