Making select and update in one query

Question

is there a query where I can do both querys in one?

This is the first

$q = \"select c.id as campaignId,c.priceFactor,
              o.cid,o.bloggerPr         


        

Answer 1

In MySQL, you can use a join right after UPDATE. In your example, this might look something like:

update Orders o
inner join Campaign c on c.id = o.cid
set
    listPrice = o.priceFactor * order.basicPrice
,   bloggerPrice = case 
        when o.bloggerPrice < o.priceFactor * order.basicPrice
            then o.priceFactor * order.basicPrice
            else bloggerPrice
        end
,   listPrice = case 
        when o.customerPrice < o.priceFactor * order.basicPrice
            then o.priceFactor * order.basicPrice
            else listPrice
        end
where o.state in (8,9)
and c.id = {$campaignId}
