Problem with MySQL via dbExpress - get invalid username/password after doing queries

Hi

Does anyone know why the MaxStmtsPerConn in the TSQLConnection component always gets set to 1 when using mysql (v4) and dbexpress?  

Everytime i create a query a new connection is opened, i thought this could support loads of queries?

This is causing me no end of grief as i soon run out of connections!

Are you using the default mysql driver for this ?  If that's the case, the mysql driver shipped with Delphi 7 was designed around 3.23 and a lot of the mysql internals have changed since then.

I assume you're using the 3.23 client libraries to connect to 4.0 that that sooner or later will cause conflicts.  I suggest you downgrade your server to the latest 3.23 and I'm sure your problems will be fixed.

If downgrading is not an option, look for an alternative method for connecting to mysql other than dbexpress.

problem is the same is 3.23 and 4.0 - as i have said in my other question (on the mysql page) it is the way dbExpress is working.

I have seen on the net another company that produces dbExpress - do you know if their driver is any better?

I really couldn't tell ... I have never used it before :(

Look at what I posted in the mysql thread and if it sounds reasonable to you, then chances are you'll be OK for the time being.  If my suggestion doesn't work for you, then give ZeosDBO a try.  It should be pretty effortless to switch the DBX stuff for ZeosDBO.
