How do I compare two columns for equality in SQL Server?

I have two columns that are joined together on certain criteria, but I would also like to check if two other columns are identical and then return a bit field if they are.

Is there a simpler solution than using CASE WHEN?

Ideally I could just use:

    SELECT Column1 = Column2 AS MyDesiredResult
      FROM Table1
INNER JOIN Table2 ON Table1.PrimaryKey = Table2.ForeignKey

Answer

What’s wrong with CASE for this? In order to see the result, you’ll need at least a byte, and that’s what you get with a single character.

CASE WHEN COLUMN1 = COLUMN2 THEN '1' ELSE '0' END AS MyDesiredResult

should work fine, and for all intents and purposes accomplishes the same thing as using a bit field.
