In the above sub routine i had tried to connect mapped database inside the subroutine.But i hardcoded manually each database.Now those databases are not fetching the contents properly because it is displaying only the rate_bang_current database contents for all other four DATABASES.How can i automatically select the database using perl without hard coding the database names and connection manually.
