update one table with data from another

Extreme SQL noob here. I have two databases (Database1, Database2). Each db has the same tables. I want to update TableA in Database2 with the data in TableA from Database1 (Database1,TableA -> Database2,TableA).

What’s the best way to do this?

Answer 1

Like this, assuming you use a dbo schema.

insert into Database2.dbo.TableA (column1, column2, etc)
select column1, column2, etc
from Database1.dbo.TableA

You might want to truncate Database2.dbo.TableA first if the incoming data should overwrite the old or you are using an identity field.

If you need the ids to be the exact same across the tables, you should disable the identity property on Database2.dbo.Table before running the script and re-enable it afterward.
