I am familiar with updates on one table but not when data spans two tables, so any help would be greatly appreciated.

I have a spreadsheet with pricing by model number and I need to update a pricing table in the database...here is the problem..

In the DB, my products_tbl has a product_id and a product_model

the table I need to update (products_groups) only has the product_id and price so the update query I need to write needs to find the products_id for a products_model then update the price.

I will need to do this on 20,000+ rows so will need to concatenate in SQL which is no problem, but the query will be difficult for me. sorry if explanation is a little difficult to understand

THanks in advance to whomever can lend a hand

Dump ExcelSheet into TempTable. If you need to do regularly you can do through SSIS Package

Update pg
Set pg.Price = T.Price
from Product_tbl pd
inner join Temptable T on T.product_model = pd.product_model
inner join products_groups pg on pg.product_id = pd.product_id
