Hello,
I`m doing a database in MySQL to catalog cds, and i`m not sure if my table
structure is the best way to do it:
Artist Table
Artist_Id int unsigned not null auto_increment primary key
Name char(120) // Artist or Band Name
Country char(30) // Artist Or Band Country
Members char(255) //

I want to mysql to store the information, but commnet maybe very long, is
there a better way to handle it instead of set a varchar(2000) or more for
a field comment in the table?
Thanks

VARCHAR has a maximum length of 2000. In MySQL 4.1, it will be converted
automatically to TEXT. But you can use TEXT in any version of MySQL.
Is that suitable for what

Below is a little PHP code snippet which works great(returns results quickly)
for single
queries. However when I put this code into a loop incrementing the order_index
and line,
my application can take as long as 2 minutes to return results. Is there any
other way
to execute this series of queries
