I’m looking to do a single query to update a database. Here is some pseudocode:
UPDATE Table1 SET Table1.Value = (SELECT Value FROM Table2 WHERE Table2.Id==2) WHERE Table1.Id == 4
This will only work if your subquery
(SELECT Value FROM Table2 WHERE Table2.Id=2)only returns one value. Also replace the==with=in your subquery as I have.I believe updating it to what I have below would make it work no matter what:
(SELECT Top (1) Value FROM Table2 WHERE Table2.Id=2)
