Queries work in sql*plus, but not PHP

Hi,

I am new to using PHP to interface with Oracle. I am developing a video store database for class. I have a nice web interface in PHP that I was using successfully to run queries. However, I recently added a column to one of my tables. I then deleted all of my tables and recreated them with the extra column using scripts I have. After I did this, I can no longer get queries to work properly with my Web interface--I never get any results.

I have the query output to the screen for debugging purposes, and when I copy the query and run it in sql*plus, the query returns results. Why is it working in sql*plus, but not PHP? Everything was working before, but now nothing! I don't get any error messages when I run the queries--it's just not returning any rows. I tried restarting Apache, etc. I'm on Windows XP using Apache 1.x and the latest version of PHP.

Thanks for any suggestions!

I think I solved the problem. I was not doing a commit. After committing, I could run my queries from PHP. Like I said, I'm new at this.
