1.9.14 & 2.2.x students enrolled in a course SQL query & show in/as PHP page

Hi there,

over the summer, when we migrate to 2.2, there is going to be a short time where some of our users have to be taking their courses in 1.9.x and also in 2.2.x.

I was thinking of creating a landing page where after they login  (in version 2.2.x ideally), it would show them a generic php page in 2.2.x of all their courses on both platforms.

I was thinking of simply writing a query to connect to both datasources on different machines and present it to them. They then click to go to their courses.

My questions are:

What would the sql statement be to get student enrolments for versions 1.9 and 2.2.x?

How could I get their userid from the page and use that as part of the "where" clause to further filter them only?

 

Here is what I got so far for version 1.9.x


SELECT c.id, c.fullname, u.firstname, u.lastname, u.email, u.id

FROM mdl_course c LEFT OUTER JOIN mdl_context cx ON c.id = cx.instanceid LEFT OUTER JOIN mdl_role_assignments ra ON cx.id = ra.contextid AND ra.roleid = '5' LEFT OUTER JOIN mdl_user u ON ra.userid = u.id

WHERE cx.contextlevel = '50'

AND u.id = = ' where/how do I get their id after they log in?'

 

And for version 2.2.x? is????

SELECT mdl_course.id,  mdl_course.category, mdl_course.shortname, mdl_course.fullname, mdl_course.timecreated, mdl_course.timemodified, mdl_course_categories.id, mdl_course_categories.name, mdl_role_assignments.userid, mdl_role_assignments.roleid, mdl_user.firstname, mdl_user.lastname, mdl_user.email, mdl_user_enrolments.enrolid, mdl_user_enrolments.userid

FROM mdl_course, mdl_course_categories, mdl_role_assignments, mdl_user, mdl_user_enrolments

WHERE mdl_user.id = mdl_role_assignments.userid

and

mdl_user.id = mdl_user_enrolments.userid

and

mdl_course.category = mdl_course_categories.id

and

mdl_role_assignments.roleid = '5';

and

mdl_user.id = ' where/how do I get their id after they log in?'

and

mdl_role_assignments.userid = = ' where/how do I get their id after they log in?'

 

Could anyone help me with rewriting the version 2.2.x using joins instead? Joins are more efficient no?

 

 

Thank you.
