I tried to formulate an import specification to import telephone account data from a .csv file. Each line in the input file included the phone number as a ten-digit string. The specification loaded this into a short text field in the table. In practice, numbers greater than 2147483647 (i.e. 2^31 - 1) elicited a "Type conversion" error. Clearly, despite the fact that Short Text was specified, the system was interpreting this as a numerical value. Does anyone know why this should be happening and how it can be avoided?
