Okay so I know how to select data from tables using Joins but how do I update whilst using this principle.

Eg.  I have 3 tables, 1: Stock, 2: StockToRecords, & 3: Records

I could do this in a select
SELECT records.recid from records
INNER JOIN StockToRecords ON Records.RecID = StockToRecords.RecID
INNER JOIN Stock ON StockToRecords.Partno = Stock.Partno
where Stock.Partno = 'banana'

So I can select based on the Stock table but how using this relation as above would I update a column in records using a where clause from stock?

Thanks in advance,

Andrew

UPDATE R
SET urColumn = newValue

from records r
INNER JOIN StockToRecords ON r.RecID = StockToRecords.RecID
INNER JOIN Stock ON StockToRecords.Partno = Stock.Partno
where Stock.Partno = 'banana'
