you can work with stored procedure like a ADOquery ..this is an simple sample...
SQL Table Users
                   id_users int
                   name varchar(50)

and this is a Stored Procedure sample
 
CREATE PROCEDURE test @name varchar(20)
 AS
select * from users where name like @name
GO

now in Delphi...add a ADOStoredProc (if you don't have an ADOconection then build  a connection string to your MS SQLserver )
in the property ProcedureName find the procedure name (in our sample test)
then in ADOStoredProc Parameters you can see the parameters (in our case @name) (it the parameter type is not asignes you can define that in our case FtString)
now to test it we are getting a button to do this..

procedure TForm1.Button1Click(Sender: TObject);
begin
ADOStoredProc1.Parameters.ParamByName('@name').value := '%some_name%';
ADOStoredProc1.ExecProc;

that's all...if you wanna see the results into dbgrid you can atach an datasource to your storedprocedure and may be you need adostoredProc1.Open;
hope this help you...
