Is there something in MySQL like IN but which uses AND instead of OR?

Question

I need a SQL statement to retrieve records where it key (or any column) is in a associate table, for example:

documentId termId
4             1
4                     


        

Answer 1

There's no straight forward functionality, but there are two options:

Using GROUP BY/HAVING

---

  SELECT t.documentid
    FROM TABLE t
   WHERE t.termid IN (1,2,3)
GROUP BY t.documentid
  HAVING COUNT(DISINCT t.termid) = 3

The caveat is that you have to use HAVING COUNT(DISTINCT because duplicates of termid being 2 for the same documentid would be a false positive. And the COUNT has to equal the number of termid values in the IN clause.

Using JOINs

---

SELECT t.documentid
  FROM TABLE t
  JOIN TABLE x ON x.termid = t.termid
              AND x.termid = 1
  JOIN TABLE y ON y.termid = t.termid
              AND y.termid = 2
  JOIN TABLE z ON z.termid = t.termid
              AND z.termid = 3

But this one can be a pain for handling criteria that changes a lot.
