a stupid question about mysql database (2)
Posted: Sat Jul 23, 2005 4:08 am
assume a table have data.
will the table loss data if i drop or add a field to the table (except field dropped)?
E.g. Fied UserInfo contains many user names (data), if I add or drop another field (i.e. place), does data of user names in field UserInfo loss?
Thanks
