Question

Well, when I named a folder with “4.0” in backup and store the name in database. When I get it from the database using perl, I changed to “4”. How can I stop the automatic conversion?

Answer 1

There are several things that can go wrong here.

• The value you have in the variable might have changed before you insert it into the database
• The database driver may think it’s a number and might change it
• The database server might change it before it stores it
• And, the same things might happen on the way out.

Check each of those things to see there the value changes. Then, focus on that part and add to your question.
