I have two tables...
table1 ( id, item, price ) values:
id | item | price
-------------
10 | book | 20
20 | copy | 30
30 | pen | 10
....table2 ( id, item, price) values:
id | item | price
-------------
10 | book | 20
20 | book | 30
Now I want to:
update table1
set table1.Price = table2.price
where table1.id = table2.id
and table1.item = table2.item.
How do I do it?
Something like this should do it :
UPDATE table1
SET table1.Price = table2.price
FROM table1 INNER JOIN table2 ON table1.id = table2.id
You can also try this:
UPDATE table1
SET price=(SELECT price FROM table2 WHERE table1.id=table2.id);
UPDATE table1 SET price = b.price FROM (SELECT id, price AS p FROM table1) a INNER JOIN table2 b on a.id = b.id
UPDATE table1 INNER JOIN table2 ON table1.id = table2.id SET table1.Price = table2.price can be usedThis will surely work:
UPDATE table1
SET table1.price=(SELECT table2.price
FROM table2
WHERE table2.id=table1.id AND table2.item=table1.item);
