This is a small tutorial for you on your query questions(no pun):
This is a simpel table called
Student in your database with four columns, StudentID, SFName,SLName, and DateCertified:
1 Venkat Raman 1/1/1908 12:00:00 AM
9 Jay Krishnaswamy 4/3/1941 12:00:00 AM
22 Nicole Kidman 4/5/2000 12:00:00 AM
23 John Pollack 1/1/2000 12:00:00 AM
--------------------------
This is a simple well known "SELECT" query
----------------------------
select SFname, SLName
from Student
where StudentID='9'
This gives the result
Jay Krishnaswamy------------------------------
Create a stored proc (testing)which shows all data in the table:
create proc testing as
select SFName, SLName
from Student
--------------------------------
Now the code you wanted

this creates a stored procedure newTest)
create proc newTest
@idss nchar(20)
as
select SFName, SLName
from Student
where @idss=SFName
---------------
when you run the following command:
exec newTest 'Jay'
you will get:
Jay krishnaswamy
I hope this helps.
