To my knowledge, your syntax above (which looks similar to INSERT INTO table (..., ..., ...) VALUES (..., ..., ...)) cannot be used for UPDATE statements. > Im wondering cause I have an INSERT query > > $query = "INSERT INTO table (var1, var2, var3) VALUES ($var1, $var2, > $var)"; > > ...but only there are like 150 different variables and it will take me > forever to write a query like > > $query = "UPDATED table SET var1='$var1', var2='$var2', var3='$var3' > WHERE username='$username'"; If you have shell access to your database server, you can always CREATE TEMPORARY TABLE and test things out on a small scale, then DROP TABLE when you're done playing.

Re: [PHP] MySQL - UPDATE & INSERT
The UPDATE syntax in the manual: http://www.mysql.com/doc/U/P/UPDATE.html UPDATE [LOW_PRIORITY] [IGNORE] tbl_name SET col_name1=expr1, [col_name2=expr2, ...] [WHERE where_definition] [LIMIT #] Yes, it is different than the INSERT syntax.
