TSQL Variable With List of Values for IN Clause

Question

I want to use a clause along the lines of \"CASE WHEN ... THEN 1 ELSE 0 END\" in a select statement. The tricky part is that I need it to work with \"value IN @List\".

Answer 1

This might be along the lines of what you need.
Note that this assumes that you have permissions and the input data has been sanitized.

From Running Dynamic Stored Procedures

CREATE PROCEDURE MyProc (@WHEREClause varchar(255))
AS

    -- Create a variable @SQLStatement
    DECLARE @SQLStatement varchar(255)

    -- Enter the dynamic SQL statement into the
    -- variable @SQLStatement
    SELECT @SQLStatement = "SELECT * FROM TableName WHERE " + @WHEREClause

    -- Execute the SQL statement
    EXEC(@SQLStatement)
