To all:
I am creating a paramaters table to store values for mulitple sctipts.
For example, I will create a Table called ScriptParameters with the fields ID, scriptname, ScriptValue, and active.
Sample data may be:
ID, scriptname, scriptvalue,active
1, fruit, apple,1
2, fruit, grapes,0
3, fruit, oranges,1
4, veggies, peas,1
5, veggies, corn,1
6, veggies, spinach,1
7, veggies, carrots,1
8, candy, chocolate,1
9, candy, lollipops,0
I want to create a query that will allow me to check and return all values with active fruit dynamically.
If I did this hardcoded, it would look like this:
SELECT * FROM ScriptParameters WHERE scriptvalue='apple' OR scriptvalue='grapes' OR scriptvalue='oranges' AND Active='1'
How can I make the scriptvalue dynamic and maintain the proper syntax?
Any advice would be greatly appreciated!

Why do you have to list all the scriptvalues? Can't you use the scriptname?
SELECT * FROM ScriptParameters WHERE scriptname = 'fruit' AND Active = 1
I suspect you might also get a lot of benefit from reading this article about catch all type queries. http://sqlinthewild.co.za/index.php/2009/03/19/catch-all-queries/[/url]

Hi,
Thank you. The part I am getting hung up on or just don't understand is having the parameters for a where statement be variable. How do I make sure the sytax stays complete.
Thank you for article will readh now.

Like this?
declare @scriptname varchar(10) = 'fruit'
SELECT * FROM ScriptParameters WHERE scriptname = @scriptname AND Active = 1
Or if you are wanting to make this into a stored procedure...
create procedure GetScriptStuff
(
@scriptname varchar(10)
) as
SELECT * FROM ScriptParameters
WHERE scriptname = @scriptname AND Active = 1
Then you could call your stored proc like this:
exec GetScriptStuff @scriptname = 'fruit'
