G'day AhmedABdo,

As a starting point, take a look at DBI: Placeholders and Bind Values.

The information in your post is rather vague and has forced me to make guesses. For instance, my first guess about Input was that it's supposed to be what's in your database; however, I see no SQL select statements to read this data. It could be from a file but there's no code performing I/O to read it. In fact, I see nothing where you get this Input.

Here's some suggestions:

• The where clause of your update statement looks like it needs more work such that you're only updating one row at a time. Maybe the addition of "and ID.Name = ?".
• The while condition looks wrong. That probably needs to be based on an SQL select statement.
• The "$run->execute" should be inside the while loop and will need arguments (to match whatever placeholders you decide to use).

Finally, telling us "it does not work" is not at all helpful. See "How do I post a question effectively?" for more details.
