If i make the following query i always have to reboot the server. So it is a little problem^^. Can someone pls look over where the mistake could be.
In gzdaten are abizt 8000 entries, diaeten 60 entries, gzprefix 80 entries and in all other one less then 20.
SELECT
org.*,
mitarbeiterstamm.*,
gzprefix.PREBEZ,
gzprefix.SORT_ID,
gzdaten.GZ,
gzdaten.GZPOST,
org_arbcodes.*,
org_qualif.*,
..... (i cut down this list for a better overview)
FROM
kilometersaetze, gzprefix, tarif_ma, gzdaten, mitarbeiterstamm, org
LEFT JOIN org_matcodes ON (org.MATCODE = org_matcodes.CODE)
LEFT JOIN fahrzeuge ON (org.KFZCODE = fahrzeuge.FAHRZEUGID )
LEFT JOIN material_saetze ON (material_saetze.MATERIAL_ID = org_matcodes.ID)
LEFT JOIN org_barcodes ON (org.BARCODE = org_barcodes.CODE),
org_arbcodes LEFT JOIN org_qualif ON (org_qualif.CODE = org_arbcodes.QUAL),
diaeten LEFT JOIN diaetensaetze ON (diaeten.BINCODE = diaetensaetze.BINCODE)
WHERE
org.DATUM BETWEEN kilometersaetze.VON AND kilometersaetze.BIS AND
gzprefix.PREBEZ = "'FIS'" AND
gzdaten.GZ = "'0" AND
(gzdaten.GZPOST IS NULL OR gzdaten.GZPOST = "") AND
gzdaten.GZPRE = gzprefix.PRENR AND
org.GZID = gzdaten.GZID AND
org.DATUM BETWEEN '2008-03-12' AND '2008-08-12' AND
org.PERSONALID = mitarbeiterstamm.PERSONALNR AND
org.DATUM BETWEEN tarif_ma.VON AND tarif_ma.BIS AND
org.ARBCODE = org_arbcodes.CODE AND
org.DIAETCODE = diaeten.CODE
ORDER BY org.DATUM
LIMIT 1000;
I already made a topic but i thought this is another problem.
Thank you in forward for the help

He's using MySQL, by the look of "LIMIT 1000;" clause.

thanks for the replies
i use MYSQL Server 2000
@ sodeep
Did you check Execution plan and high cost?
No I haven't, I don't know what this is, can I make this like a normal query, because I maybe not allowed to go to the server (it is my summerjob).
@ Peso
Do you have proper indexes?
Yes, every table has a unique id. They are named, *CODE or *ID
If I make the following query it works (but I need both combinations :( )
SELECT
org.*,
mitarbeiterstamm.*,
gzprefix.PREBEZ,
gzprefix.SORT_ID,
gzdaten.GZ,
gzdaten.GZPOST,
org_arbcodes.*,
org_qualif.*,
..... (i cut down this list for a better overview)
FROM
kilometersaetze, gzprefix, tarif_ma, gzdaten, mitarbeiterstamm, org
LEFT JOIN org_matcodes ON (org.MATCODE = org_matcodes.CODE)
LEFT JOIN fahrzeuge ON (org.KFZCODE = fahrzeuge.FAHRZEUGID )
LEFT JOIN material_saetze ON (material_saetze.MATERIAL_ID = org_matcodes.ID)
LEFT JOIN org_barcodes ON (org.BARCODE = org_barcodes.CODE),
org_arbcodes LEFT JOIN org_qualif ON (org_qualif.CODE = org_arbcodes.QUAL),
diaeten LEFT JOIN diaetensaetze ON (diaeten.BINCODE = diaetensaetze.BINCODE)
WHERE
org.DATUM BETWEEN kilometersaetze.VON AND kilometersaetze.BIS AND
gzprefix.PREBEZ = "ISC" AND
gzdaten.GZ = "08011" AND
gzdaten.GZPOST = "00" AND //this is a query which i use to find projects were the GZPOST is set
gzdaten.GZPOST IS NULL OR gzdaten.GZPOST = "") AND
gzdaten.GZPRE = gzprefix.PRENR AND
org.GZID = gzdaten.GZID AND
org.DATUM BETWEEN '2008-03-12' AND '2008-08-12' AND
org.PERSONALID = mitarbeiterstamm.PERSONALNR AND
org.DATUM BETWEEN tarif_ma.VON AND tarif_ma.BIS AND
org.ARBCODE = org_arbcodes.CODE AND
org.DIAETCODE = diaeten.CODE
ORDER BY org.DATUM
LIMIT 1000;
Sry that I forgot important information.

"proper indexes" does not just mean a unique ID. and given that you are using MySQL, perhaps you would be better advised to post on a MySQL Forum. This site is dedicated to Microsoft SQL Server

Still, Microsoft SQL Server does not support the last line of your query, the "LIMIT 1000;".
Thus we think you are using MySQL database on a Microsoft Windows 2000 Server.

Oh ok, em, I had a look (or asked). Finally it is like you said Peso. Sry for the trouble.
But can you find a mistake in the query?

The query is really really slow because you return ALL columns in almost ALL tables by using * for column name.
So you will have a lot of table scans. You cannot use any index with this approach.

so you're still using LIMIT...? so you're NOT using SQL Server
