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

Viewed 253045

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

CASE WHEN is the better option

SELECT 
  CASE WHEN COLUMN1 = COLUMN2 
    THEN '1' 
    ELSE '0' 
  END 
  AS MyDesiredResult
FROM Table1
INNER JOIN Table2 ON Table1.PrimaryKey = Table2.ForeignKey

The use of IIF? And it depends on version of SQL Server.

SELECT
IIF(Column1 = Column2, 1, 0) AS MyDesiredResult
FROM Table;
