Is A.Account_Number an NVarchar()? If so then you should CAST C.Customer_ID to NVarchar() in your ON clause.

Try this:

select A.Account_number, A.Customer_name, A.Known_As,

A.Legacy_Account_Number, A.Account_Established_Date,

CASE A.Customer_Status

WHEN 'I' THEN 0

ELSE 1

END,

A.Account_Established_Date

from

dbo.BILL_TO_Customers A

left outer join dbo.Customers C

on A.Account_number = C.CustomerID

where

C.CustomerID is null

If everything seems to be going well, you have obviously overlooked something.

So... what do you think an 'A' should convert to when converting to an INT? Or do you just want to ignore it?

If it is an 'I' then 0 else 1.

Jeff, been try to help him, but we can't even get him to help himself. I have pointed him toward your article on how to ask for help many times, but he just doesn't seem to get it.

I used a CAST function for the value

Case When A.Customer_Status = 'I' THEN CAST ('0' AS int) ELSE CAST('1' AS int) END

So status in the table should be updated to 1 if the value in the view is A, if it is I then it will update to 0

Lynn the create table statement was wrong, what about the datatypes, and how many value lines do you need

Yep... thought I'd give it one more try. I'm moving on...
