I've imported an excel table into sql. However the field "CustomerNo" is made up of eight chars (i.e. 80000001, 80000002, 80000003.....80000045, etc). But when I view the table in SQL, it shows the values as 8e+007.
What type of field is CustomerNo is your sql table? How is the column formatted in the excel sheet? It sounds like you imported the field from a general format in excel to a varchar in sql. Format the column in excel to numeric fixed with no decimal places.
