SQL command not functioning as expected

Question

Hi am trying to update a table with the emails from another table using ids that match in both tables. I must be doing it wrong because i get these errors

"Msg 156, Level 15, State 1, Line 10
Incorrect syntax near the keyword 'IN'.
Msg 1087, Level 15, State 2, Line 10
Must declare the table variable "@ListofPropIDs".
Msg 1087, Level 15, State 2, Line 11
Must declare the table variable "@ListofPropIDs"."

Any help would be appreciated.

DECLARE @ListOfUserIdsAndEmails TABLE(UserEmail VARCHAR(100),IDs VARCHAR(100));

INSERT INTO         @ListOfUserIdsAndEmails 
    SELECT              UserId, Username
    FROM                aspnet_Users

    UPDATE          UserDetails
    SET             UserEmail = IN ( SELECT UserEmail from @ListofPropIDs)
    WHERE           UserIdn   = IN ( SELECT IDs from @ListofPropIDs)

GO

Answer 1

Try this:

Fix your first INSERT:

INSERT INTO         @ListOfUserIdsAndEmails 
SELECT              Username, UserId
FROM                aspnet_Users


UPDATE          UD
SET             UserEmail = P.UserEmail 
FROM UserDetails AS UD
JOIN @ListOfUserIdsAndEmailsAS P
  ON P.IDs = UD.USerIdn

However if your getting an error saying that conversion error on the UserEmail, are you sure that UserEmail is VARCHAR on the UserDetails table? Maybe you should post that table structure.

The variables need switching from

DECLARE @ListOfUserIdsAndEmails TABLE( UserEmail nvarchar(256),IDs uniqueidentifier);

to this

DECLARE @ListOfUserIdsAndEmails TABLE(IDs uniqueidentifier, UserEmail nvarchar(256));
