Sieht sehr chaotisch aus mit dem CASE-WHEN-THEN.
Habe den Query mal getestet: "
#1064 - You have an error in your SQL syntax. Check the manual that corresponds to your MySQL server version for the right syntax to use near 'FROM asd GROUP BY f1, f2 LIMIT 0, 30' at line 8" :)
Code:
1> SELECT
2> CASE WHEN COUNT( f1 ) >1
3> THEN COUNT( f1 )
4> END AS cf1,
5> CASE WHEN COUNT( f2 ) = cf1
6> THEN COUNT( f2 )
7> END AS cf2, f1, f2,
8> FROM asd
9> GROUP BY f1, f2
10> LIMIT 0 , 30
