hi,
You can check out all the options here in the mysql manual.
6.4.4 UPDATE Syntax
Using "update sometable set somecolumn = 'some coumn data'"; is a really simple option. when using a database you will want to use the where limiter so that you don't update all records in the database.
Use something like "update sometable set somecolumn = 'some coumn data' where someothercolumn = 45";
thanks,
