Update table based on value in related table

Posted on 2011-09-26
Last Modified: 2012-05-12
I have 2 tables: aspnet_Users and tblUserProfileData.

Who can I update all users in tblUserProfileData that has one spesific ApplicationId in aspnet_users? The relation between the tables are tblUserProfileData.UserId and aspnet_Users.UserId.

I need to set tblUserProfileData.Payment = '0' where aspnet_Users.ApplicationId = 'aca98bd7-4fee-4bf3-7d21-3b88c9457d57'

This is a select statement that returns all users where I need to set tblUserProfileData.Payment = '0':

SELECT     tblUserProfileData.UserId, tblUserProfileData.Payment, aspnet_Users.ApplicationId
FROM         tblUserProfileData INNER JOIN
                      aspnet_Users ON tblUserProfileData.UserId = aspnet_Users.UserId
WHERE     (aspnet_Users.ApplicationId = 'aca98bd7-4fee-4bf3-7d21-3b88c9457d57')

pratima_mcs: When I run the SQL I get the following error:

Column or expression 'Payment' cannot be updated.
SQL Execution Error.
Error Source: .Net.SqlClient Data Provider
Error Message: Invalid object name 'A'

Any clue?
Thanks :)

are you sure you put the table alias A

Update A

Set A.Payment = '0'
FROM         tblUserProfileData A INNER JOIN
                      aspnet_Users ON A.UserId = aspnet_Users.UserId
WHERE     (aspnet_Users.ApplicationId = 'aca98bd7-4fee-4bf3-7d21-3b88c9457d57')
