Append or Update Query

Posted on 2014-10-04

I want to run a query that updates a record I a table if the record already exists.   But if the record does not exist I want it to create a new record in the table.

The source table is "Source".  The destination table is "Destination"

The both have a key field named "RecordID"

If I just try to run an update query it fails because the record isn't there.  But if I run an append query it works fine if the record is already there.

Confused!!

this can be done by using a Left join instead of an Inner join in your update query


update source LEFT JOIN destination
ON source.recordid = destination.recordid
SET destination.[field1] = [source].[field1], destination.[field2] = [source].[field2], destination.[field3] = [source].[field3];

What Rey said!  (no points please)

Some people call this an UPSERT query.  In SQL Server, they have a similar query syntax called MERGE which gives you the ability to Update and Append at the same time, and you can even get a count of how many of each action are completed.
