Converting varchar field into primary key
Hello, I'm creating a new MySQL database from an existing Filemaker db. My problem is that some of the existing 'numbers' in one column (it was a text field in FMP) have leading zeros. eg: 003, 0007, 012, 001234. I need to maintain these numbers 'as is' - complete with zeros. I've tried all the numeric data types and they all seem to strip these leading zeros. Is it possible to have a numeric field type which will maintain those zeros? I want this column to become the primary key. regards kim -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/[EMAIL PROTECTED]

An integer value does not have something as leading zeros. Why not make the VARCHAR the PK and keep the datatype? Martijn Tonies Database Workbench - development tool for MySQL, and more!

The manual states (among other things) declaring a column: int(6) zerofill will left pad the column with zeros. 003 will become 03. -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/[EMAIL PROTECTED]
