Re: making two fields primary key ????
This is covered in the manual for mysql . Look up primary key. To create table with primary key the syntax will include: PRIMARY KEY (colname1, colname2 ...) To alter an existing table will be miore difficult, since you have to ensure the data already in the table does not breach the new primary key rule. The syntax will be ALTER TABLE tablename ADD PRIMARY KEY (colname1, colname2,...) If you havent done so I suggest you download a copy of the manual. As computer manual go it is first class and will cover all that you need.

Re: mysql permanent connections
What are the advantages and disadvantages of permanent connections to mysql (using php mysql_pconnect())? I am developing a site where each users session will have a number of interactions with the database from different web pages. Should I use permanent connections? How can I close a permanent connection? (Documentation says mysql_close() does not close permanent connections) Do permanet connections die when the internet connection is broken?

Re users in mysql
I have set up mysql under redhat 7.3 and imported the database from mysql
running on windows.
I have the root user running using passwords, but i cannot get the other
users to log on even thogh the passwords shoudl have been carrid across with
the import.
I have tried to reset the user passwords but still cannot get a logon.
For exmple if i log on and change a user password with:
GRANT INSERT ON stamps.customers TO reguser@'%'
IDENTIFIED BY 'regpassword';
should let me log on as
mysql -D stamps -u reguser -pregpassword
I get the error message:
ERROR 1045 Access denied for user 'reguser@localhost' (Using password = YES)
I have tried changing the password with
update mysql.user set password = PASSWORD('regpassword') and this does not
help
Can anyone suggest what I need todo?
Do I need to drop the users and run the full set of grant scripts again?
Regards
Peter Goggin

Re: Oracle to Mysql
There are several major differences that you will need to consider. 1. So far as I know MySQL does not allow you to assign tables and indexes to table spaces, hence load spreading is much more difficult. You cannot split tables and indexes so that they reside on differentt disks. 2. There are no stored procedures and triggers available in MySQL. 3. You will need to use the Innodb or equivalent extensions to get transaction processing. 4. The table and index creation syntax is different with MySQL. (Personally I found MySQL somewhat more logical). If you want to discuss the issues in more detail please e-mail me directly.

Re: Re MySQL on Redhat 7.3
I have got the msql server running and now need to configure it. In particular I want to set it up to use innodb tables. When I set up mysql on win98 I used the mysql-max release which comes with built in Innodb support and provides sample my.cnf files with the instructions for setting up Innodb table spaces. I cannot find anything similar from the RedHat installation. The rpms installed are: mysql-3.23.49-3 mysql-devel-3.23.49-3 mysql-client9-3.23.22-6 mysql-server3.23.49-3 On looking at the mysql site, it looks as though I need another rpm, mysql-max-3.23.49-3 which should be installed after the others. Is this correct and if so where can I down load it.
