There's a huge perl process running, and we don't have access to the source code. We only have access to a loader script, which starts the entire process.
This process is doing lots of SQL via DBI. We'd like to change that SQL a little bit. This can be done via DBI callbacks as described in the manual: http://search.cpan.org/~timb/DBI-1.622/DBI.pm#Callbacks Callbacks are registered on DBI object instances. When the process is started we don't have access to handles, they have not been created yet. However, in theory, we could load the DBI module in the loader script so the DBI code would be there, and then we could register callbacks on the *class*, not on the *instance*, and they would be called *from* the instance. In other words, global callbacks. In practice it looks like this isn't supported. Or is it? Michael
