I have added a column to several tables, and I populate the column using a couple of stored procedures in a huge import process. I am getting this error returned when I run the main stored procedure. I can run all of my individual stored procedures which are called once for each table where the column is located. I don't get this error. Can anyone give me an idea on what the error means. I am sorry I can't be more specific but the process is very long and complicated.
