SELECT      ISNULL currate currentrate  1    FROM       is less verbose than the winning answer and does the same thing  https   msdn microsoft com en-us library ms184325 aspx

SELECT orderhed ordernum  orderhed orderdate  currrate currencycode     case currrate currentrate  when null then 1 else currrate currentrate end  FROM orderhed LEFT OUTER JOIN currrate ON orderhed company   currrate company AND orderhed orderdate   currrate effectivedate

a  If you want 0 when value is null  SELECT isnull PartNum 0  AS PartNumber  PartID FROM Part   b  If you want 0 when value is null and otherwise 1  SELECT     CASE     WHEN PartNum IS NULL THEN 0     ELSE 1   END  AS PartNumber    PartID FROM Part

You can use COALESCE   SELECT  orderhed ordernum       orderhed orderdate       currrate currencycode        coalesce currrate currentrate  1  as currentrate FROM orderhed  LEFT OUTER JOIN currrate      ON orderhed company   currrate company      AND orderhed orderdate   currrate effectivedate   Or even IsNull     SELECT  orderhed ordernum       orderhed orderdate       currrate currencycode        IsNull currrate currentrate  1  as currentrate FROM orderhed  LEFT OUTER JOIN currrate      ON orderhed company   currrate company      AND orderhed orderdate   currrate effectivedate   Here is an article to help decide between COALESCE and IsNull   http   www mssqltips com sqlservertip 2689 deciding-between-coalesce-and-isnull-in-sql-server
