Hi Peter thanks for the response.

I started writing a query to insert then on duplicate update but i was not able to get it to work.

This is where i am at the moment, the query doesn't work and i am at a loss as to how.

INSERT INTO CONFIGVALUE (CONFIGVALUE.CODE,CONFIGVALUE.VAL) VALUES ('IMAGE','image_name'), ('IMAGE_UPDATE_MODE','2')
SELECT CONFIGOBJECT.PARENT AS tmpPARENT, CONFIGOBJECT.COID AS tmpCOCOID, CONFIGVALUE.VAL AS tmpCVVALUE, CONFIGVALUE.CODE AS tmpCVCODE FROM CONFIGOBJECT
WHERE CONFIGOBJECT.PARENT IN
(
SELECT CONFIGOBJECT.PARENT FROM CONFIGVALUE JOIN CONFIGOBJECT ON CONFIGVALUE.COID=CONFIGOBJECT.COID WHERE CONFIGOBJECT.PARENT =15 AND CONFIGOBJECT.COTYPE > 2
)
ON DUPLICATE KEY UPDATE CONFIGOBJECT.COID=tmpCOCOID, CONFIGOBJECT.PARENT=tmpPARENT, CONFIGVALUE.VAL=tmpCVVALUE, CONFIGVALUE.CODE=tmpCVCODE


I've ran into a few different syntax errors while trying to modify the query and in all honesty I haven't got a clue anymore.

Should i be selecting everything from the table where the data does not exist, then insert into the database?

I'm concerned that just inserting the data will give me extra rows where i don't need them as opposed to inserting them for the rows i want. This made me think i would need to use some sort of sub query and maybe select into a temporary database then insert/update.

Could you provide some advice on this?

Thanks,

PhilB
