select count(): msg#00006db.postgresql.german
Hallo, ich experementiere gerade etwas mit dem ldap-postgresbackend und habe da leider sehr viele Anweisungen die SELECT COUNT(*) FROM (manchmal auch mit join sind). Leider ist so ein SELECT COUNT nicht gerade besonders schnell, ich kann den query nunmal aber nicht ändern, hat vielleicht jemand nen Tip wie ich den query schneller bekommen? Indizes habe ich als btree gesetzt. Danke Thomas Hoth ---------------------------(end of broadcast)--------------------------- TIP 9: In versions below 8.0, the planner will ignore your desire to choose an index scan if your joining column's datatypes do not match
