hi every one
i have a sql database with a udf getItemBalance that accepts itemId and returns its balance
in visual basic i am using a strongly typed dataset
is there a way to use the udf directly in the dataset with code like :
dim balance as decimal=getItemBalance(ItemID)
?
i mean without using the command object ?
thanks

I seriously doubt it. How else will the application get access to the database?

If you are using EF then you can map this in your EF model, Still it would probably use command object behind the scenes.

actually it is quiet possible
i did some tries and found this way :
1-right click on the dataset in the datasources and configure it with wizard to add the udf from the underlying database
2-now you can use the udf directly by using the queriesTableAdapter like this :

VB

Dim da As New DataSetTableAdapters.QueriesTableAdapter
        s = da.getItemBalance(i)

it was just so hard for me to find the answer (3 hours of googling in vain)
so i thought to share the solution with every one

thanks every body
