Hi,

I have one stored procedure...
I have to sort result set by input parameter @SortColumn

CREATE PROC testProc( @SortColumn VARCHAR(60)) -- ColumnName + ASC/DESC
AS
BEGIN
SELECT * FROM TableName ORDER BY @sortColumn -- Is it possible without dynamic query
END

nope you cant pass the columnname and sort order unless you use dynamical sql. columnname alone you can pass but direction has to static.

Kinda sorta.. You can make use of CASE expressions to do a "dynamic" sort. But, not quite to the level of just sorting on the variable itself. For example:

ORDER BY
	CASE
		WHEN @SortColumn = 'CustomerName' AND @SortDir = 'ASC' 
			THEN CustomerName 
	END ASC, 
	CASE 
		WHEN @SortColumn = 'CustomerName' AND @SortDir = 'DESC' 
			THEN CustomerName 
	END DESC,
	...

yes.. i have already done like Lamprey's method... but the problem is i have column names of types varchar(250), datetime2, bigint. Thats why casted all columns to VARCHAR(250)...

The sorting order for Bigint will vary... right? What is the fix for this problem?
