Bulk Record Update with SQL

Question

I have two tables in a SQL Server 2008 environment with the following structure

Table1
- ID
- DescriptionID
- Description

Table2
- ID
- Description
<         


        

Answer 1

Your approach is OK

Maybe slightly clearer (to me anyway!)

UPDATE
  T1
SET
  [Description] = t2.[Description]
FROM
   Table1 T1
   JOIN
   [Table2] t2 ON t2.[ID] = t1.DescriptionID

Both this and your query should run the same performance wise because it is the same query, just laid out differently.
