I made this procedure..

SQL

ALTER PROCEDURE [dbo].[MyProcedure]
            @pSelect nvarchar
AS
BEGIN
    SET NOCOUNT ON;

    select @pSelect from tabel1
END

I want to pass a select query like from c# code to this stored procedure

C#

MyProcedure("column1,column2");

How could I do this because stored procedure treat my parameter as a string and it behaves like

SQL

select N'column1,column2' from tabel1

pls help me

or provide a better option for this

Uses the Exec (Execute) statement.

SQL

ALTER PROCEDURE [dbo].[MyProcedure]
            @pSelect nvarchar
AS
BEGIN
    SET NOCOUNT ON;
    Exec('Select ' + @pSelect + ' from tabel1;');
END

Solution 1

Try:

SQL

EXEC ('SELECT ' + @pSelect + ' FROM Table1')

[edit]
But, be very careful - you need to vet @pSelect pretty carefully, as this is a good source of SQL injection attacks!
