I’m new to this forum. Aren’t two of the above SQL statements in error? Specifically:

UPDATE TableName

FROM AnotherTable
WHERE TableName.Column1 = TableName.Column1

Shouldn’t the WHERE read:

WHERE TableName.Column1 = AnotherTable.Column1

? Just curious…

I had an amazing experience a few months ago at work (I’m the SQL Server DBA). I blew the minds of my boss, who has taught SQL Server, and our GIS admin, when I told and showed them that you can update data from views. They both thought that views were read-only.

A bit of a rude awakening for them, they did not know that permissions were equally important for views as for tables.
