  1. To save your time I'll assume that my readers know what Moodle is otherwise this post will not be relevant to them. For info. about Moodle please visit the official website The Problem: Moodle has it's own reports module where you can use a well organized interface for pulling out different reports about the activities of the users. For me as a course tutor, I need to have a quick check on the assignments submitted by my students in a certain course, certain course topic. The current reports module in Moodle is not straight forward with that regard. It pulls more data than I need which kind of doesn't highlight the parts that I'm interested in. I also hate to login every time I need to check the assignments submission. Moodle usually is a bit slow script. The Solution: It would be more practical to write a code that queries the Moodle data base and displays only what I need. A wizard interface would be ideal in my situation. Just to be specific, I'm using: Moodle version: 1.9 PHP version 5.2.17 MySQL version 5.5.29-log Application Outline: 1- A code to connect to the database : db-config.php, that will be included wheneverf we need to query the database 2- The index.php includes the db-config.php and: connects to the Moodle DB query table mdl_course to select the id and fullname fields to populate a drop-down list for the user to choose. posts the user input to sections.php 3- The sections.php will: connect to the Moodle DB query table mdl_course_sections and select the sections field that match the previously selected course id. populate a drop-down list for the user to choose posts the user input to report.php 4- Finally the report.php will: connect to the Moodle DB query mdl_assignment, mdl_assignment_submissions and mdl_user using RIGHT JOIN on the id field select only the submitted assignments using WHERE ( --- OR ----) AND ------ based on the user input, ie the course and section you selected in the previous steps in the wizard. use a while loop to display the record set in a table The Code: I tried to post the code using the BBcode but it doesn't show in the preview, so I'll try to attach it. Your feedbak is most welcome Thank you db-config.phpindex.phpsections.phpreport.php
  2. So often I need to query several table that are linked through some key.I never understood the difference between different types of JOIN although I used it in one of my application, but it just worked without knowing how.The main problem with using the wrong JOIN is that you get lots of duplicated records no matter you try to filter the results using WHEREMy question is general and not specific to a certain case. I only need to understand the difference between the different types of Join.Can any expert help me?Thanks
