Hi,
Have you indexed the fields you're using in the JOIN clauses?

Subject: Problem with EQ_REF and ALL
Someone please help me...
I have 2 queries (in the end I end up joining them with a LEFT JOIN, but
they don't "work" properly)
SELECT *
FROM tbl_v_batch b
LEFT JOIN tbl_v_levering l ON l.ver_lev_id = b.batch_lever_id
LEFT JOIN tbl_klanten k ON k.klant_id = l.ver_lev_klant_id
This one gives ALL on tbl_v_levering l
SELECT *
FROM tbl_v_batch b
LEFT JOIN tbl_v_bestelbon bb ON bb.ver_id = b.batch_bestel_id
LEFT JOIN tbl_klanten k1 ON k1.klant_id = bb.ver_klant_id
This one, on the other hand is correct and gives EQ_REF !
How is this possible ?
It is almost exactly the same table structure :s...
Somebody please help..
