Thread: Can't get the Update statement to work

I'm trying to get all the names of my movie files from a directory and i'm trying to store them in a database under the column movies.
One other column in the database labeled music already has some data, and the rows under the Movie column are null, so I'm trying to update these values using the update statement.

The program runs successfully but the data i'm trying to get is not stored in the database, the update statement i think is not working.

what do you think may be the problem? thanks
