I would like to order (dynamic) on more than 1 column....
So in case of @SortOrder = 1 I would like to order by CompanyName and also on ContactTitle as the second order column

ORDER BY CASE WHEN @SortOrder = 1 THEN CompanyName, ContactTitle
gives an error...

CREATE PROCEDURE ps_Customers_SELECT_DynamicOrderBy
@SortOrder tinyint = NULL
AS
SELECT CompanyName,
ContactName,
ContactTitle
FROM Customers
ORDER BY CASE WHEN @SortOrder = 1 THEN CompanyName
WHEN @SortOrder = 2 THEN ContactName
ELSE ContactTitle
END"

You will need a second CASE Statement:

CREATE PROCEDURE ps_Customers_SELECT_DynamicOrderBy
@SortOrder tinyint = NULL
AS
SELECT CompanyName,
ContactName,
ContactTitle
FROM Customers
ORDER BY
CASE
WHEN @SortOrder = 1 THEN CompanyName
WHEN @SortOrder = 2 THEN ContactName
ELSE ContactTitle
END,
CASE
WHEN @SortOrder = 1 THEN ContactName
WHEN @SortOrder = 2 THEN CompanyName
ELSE ContactTitle
END

Owais

Make it idiot proof and someone will make a better idiot
