Re: What is wrong with this SQL - Mailing list pgsql-novice

Thanks Chad,
I 'll have a go at it. One thing though if I want to update the price as an
increase in terms of a percent i.e. instead of it being 200 to have it +15%
how would you go about in achieving this.

Is it possible to add a formula after the SET = ((price*0.15)+price)


Cheers

Norman

could it be that you want this?

update price
set price.price = 200
where(price RIGHT JOIN product ON price.product = product.id) as price RIGHT
JOIN
supplier ON product.supplier = supplier.id
WHERE (((supplier.id)=4) AND ((supplier.status)=1) AND
((product.status)=1) AND ((price.type)=1) AND ((product.id)=100902));

Im not sure if this works, but it should start you down the correct road.

Thanks
 Chad
