"moreover the similar post was posted on Feb 27, 2012 at 07:26 UTC."

I don't know what point you're trying to make here. I simply stated that you've previously posted regarding DBIx::Class issues (though without actually mentioning the module you're using). Are you suggesting that you should forget the advice you've been given when you experience a similar problem after a few days have gone by?

"The link you posted Re:Databse MySQL Perl had a different concept than this one. Here there are two arguments, there it was one."

And?

"DBIx::Class is very vast and it would take a good amount of time to read it."

It may come as a surprise to you, you will have to spend time learning to use tools if you choose to use them.
