Reports: Ad-hoc database queries

Maintained by Tim at Lone Pine Koala Sanctuary Tim Hunt, at the OU (Perry building) Mahmoud Kassaei
This report plugin allows Administrators to set up arbitrary database queries to act as ad-hoc reports. Reports can be of two types, either run on demand, or scheduled to run automatically. Other users with the right capability can go in and see a list of queries that they have access to. Results can be viewed on-screen or downloaded as CSV.

This report, created by The Open University, lets Administrators set up arbitrary SQL select queries that anyone with the appropriate permissions can then run. Reports can be set to be runnable on-demand, or automatically run weekly or monthly.

The results are displayed as a fairly plain HTML table, and can also be downloaded as CSV.

The idea is that this lets you quicly set up ad-hoc reports, without having to create a whole new admin report plugin.

    Ah! We just foudn this bug ourselves last week, and our fix, which is the same as yours, is just going through testing.

    Glad to hear that it was found.

    I'm currently looking deeper into the code, and I am looking at some enhancements to meet my needs (maybe something you would be interested in). One is to have a flag to determine if emails are sent out or not if the result set is empty (helps with sending alerts).

    The other is to add an hourly option to the schedule to assist with hourly scheduled reports. This for me is useful when writing queries that will be used as alerts to specific users (mostly for teachers). I'm still working out the logic for this one.

    Why have I an error near 'Add_Discussion_Forum_Essentiels('%DCP98', '%Forum des Essentiels%', 123) LIMIT 0' at line 1 Add_Discussion_Forum_Essentiels('%DCP98', '%Forum des Essentiels%', 123) LIMIT 0, 2 [array egg]. My line contains only Add_Discussion_Forum_Essentiels('%DCP98', '%Forum des Essentiels%', 123). Why adding LIMIT to my line ???

    A couple of questions about changing run time of scheduled reports

    For reference, all my ad-hoc scheduled tasks run at 10 minutes after every hour and all reports have the "Scheduled, Daily" option.

    Question 1 - if a report is set to "Scheduled, daily" and it fails to run for some reason at, say, 7:10am, how would I "reset" it so that scheduled tasks can run it again later the same day?

    Question 2 - what is the latest time I can edit a report, and change the time, so that it is still run? For example, if I edit a scheduled report that was scheduled to run at 7:10am and save it at 7:08am, will it be run at 7:10am?

    Just wondering for debugging purposes. Thanks again for a great plugin that, quite frankly, my group could not do without.

    Reports run when cron triggers the scheduled task. That is unlikely to be exactly on the hour.

    I am afraid that the only way to find out exactly how it works is to read the code starting at (It is not particularly complicated.)

    Hi is it possible to add a extra roll to report_customsql?

    Well, technically you need to ask 'Is it possible to add extra capabilities ...'. The only way to do that is to edit the code. Specifically you would need to add them to this list:

    You also need to remember that these reports live in the System context, and only a few roles are assigned in that context. (E.g. Teacher role only exists inside a particular course, and these reports are outside all courses.)

    Since I updated to version 2018080900, I've noticed that the links don't display as links anymore, just as html text. For example I used the code (postgreSQL): select '' || c.fullname || '' "Course"
    Has some setting changed that I need to review?

    Oops sorry that didn't work I used the code without the spaces select ' < a h r e f = " % % WWWROOT % % / course / view . php % % Q % % id = ' || CAST (c . id AS VARCHAR) || '">' || c.fullname || '< / a >' "Course"

    Hi. Does this do paging for the query results html table?
  • Tim at Lone Pine Koala Sanctuary

    No, by design. There is a hard limit of 5000 rows on what one query can return, so it is just simpler to run the query once and show all the results.

    Hello, I want to setup automatic reports to show a list of students and their activity completion for a specific course, from a specific group or cohort. I know you can run a completion report on a course in moodle but I can't see a way to filter by cohort of group therefore I see 1000's of activity completion records. Will this plugin provide me with a solution to generating custom reports? Appreciate the advice. Tim

    Hello. I'm a new user trying to schedule a report to export to a shared drive path/directory. I am receiving an error that it does not exist. Is there any documentation that exist. Also, is there any hope that the hard limit of 5000 on the rows could be raised?
