Question

I have a select query which works correctly with the below output:

I would like to create an update statement to set the value of the despgoods_alldetails.loadid column = loaddetails.loadid where despgoods_alldetails_despgoodsid=loaddetails.despgoodsid.loadid.

I was thinking along the lines of

update despgoods_alldetails
set despgoods_alldetails.loadid = loaddetails.loadid
where despgoods_alldetails.despgoodsid=loaddetails.despgoodsid

This query fails with the below error:

any idea how I can get this update statement to work?

Thanks,
Ryan

Almost had it, you just need a reference to the second table.

UPDATE despgoods_alldetails, loaddetails
    SET despgoods_alldetails.loadid = loaddetails.loadid
    WHERE despgoods_alldetails.despgoodsid=loaddetails.despgoodsid
