mysql_query() doesn't always return a valid result identifier if an error

They are mysql binary logs of updates to your databases, and are usually
only needed for replication across multiple servers. If you don't need this,
remove or comment out the log-bin line from /etc/my.cnf and restart mysqld,
then you can delete them.

In your original message, you said "You will get a summary of prices by type

the price columns from any rows that are eliminated by the GROUP BY clause.

Create another table with an id column and a code column, and for each code
insert a column with the id of the row in the original database and the
code. Then do an SQL join to search. For example:

Yes, I know from experience, it's the best way to do it.
And if you need to get the number generated by an auto_increment column in
an insert, you can use last_insert_id() (or mysql_insert_id() with php).
