I have three(3) instances of an application inserting data into a MYSQL (4.X)
database. I have to change the password.
I would like to know, if I can change the password of the application on the
server without disrupting existing
connections then modify the password in the startup file for the
Hi Dan,
It would be a pretty large table of changes, but this solution would work,

Thanks for your help. I created this example to try to simplify my real
