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.

    Hi to all. I have a question. I Have created a database activity in wich student insert their name, activities and hours of activity. How (with a sql query) can I get the amount of the hours for each student? Thank you very much

    I'm writing a report that has a username column that I would like to make into a hyperlink to loginas the particular user. Question - any way to get the required sesskey using SQL commands?
    Thanks again,

    I think the reason sesskey exists is precisely to stop that sort of dangerous direct linking.

    However, it would be possible to add another of the %%...%% tokens. E.g. we could have %%SESSKEY%% that gets replaced by the current user's sesskey in the output code. E.g. about here: add a line

    $value = str_replace('%%SESSKEY%%', sesskey(), $value);

    However, I am a bit reluctant to add that to the official version of the plugin.

    Re: Adding %%SESSKEY%%

    No worries. I can change in my version. But your answer got me to thinking - Is there a better, safer way to accomplish what I want? Basically, we have a situation where an administrator has to loginas hundreds of users to change some data. The link in the report is just an attempt to save them a few mouse clicks for each user. If there is another way via the plugin to do this, I'm all ears.

    Re: Adding "Expand all"

    I have written over a hundred reports that I have put into several categories. Question - how would someone add an "Expand all" to the top of the form (like other forms)?

    Expand all would be a JavaScript change. Probably not too hard to do.

    Since all the data behind Moodle is in a database, it is quite easy to change things if you can acess the database directly. It is also possible to screw up the data directly, if you make a mistake. So, be careful.

    I am using Moodle 3.3 (Build: 20170515).

    I am getting this error. Is it because my Moodle version is not supported?

    Validating report_customsql ... Error

    Read the error message: "Write access check [/opt/bitnami/apps/moodle/htdocs/report]"

    It looks like the file permissions are not right on your server.

    For the error above, if you execute the commands below, the installation will go through.
    I wondering why need to run the command below though.

    sudo chown -R bitnami:daemon /opt/bitnami/apps/moodle/htdocs/report
    sudo chmod -R g+w /opt/bitnami/apps/moodle/htdocs/report

    So the clue is in the message... you've installed the plugin in the blocks folder but it should be in the reports folder smile

    Hi smile are there any plans to certify this for use with moodle 3.2/3.3? I have a managed site and the provider won't install any plugins that aren't listed as supported. Many thanks.

    I can't get scheduled reports to email at all.

    Email from my server works. I've set up two users: 1 a site admin, and 1 with `report/customsql:view`, and set these usernames as the recipients of a weekly report. I can see that the report is running: It tells me the latest time it ran and shows me the previous outputs that it generated, yet I get no emails. In the standard log for the report_customsql component there are entries for viewed and edited but none for notification.

    How do I test that a scheduled weekly or monthly report runs? - I'd like a "run now" sort of option so I don't have to wait a week to find out that my query was actually buggy.

    What is the first day of the week? Is that a Sunday or a Monday? The accepted answer is different depending on where you live. Here people respond "Monday".

    I'm confused by the `%%STARTTIME%%` and `%%ENDTIME%%` settings. There's no explanation of how this relates to the date it runs in the interface and even the code seems a little confusing to me. Is the start time the beginning of the *previous* week and the end the end of the day before the report runs again? That's what I expect, so I could report on things that happened in the last week up until right now. I can't test these in a normal on-demand report since they don't get replaced.

    Minor niggle: If I set up a report as "on demand" then run it, then change its type to "daily", I see "this report was run on (date)" in the text next to it. If I then open the report, the screen then says "This query has not yet been run.".

    To answer most of those questions with full certainty, I would have to check what the code is doing. And, I know that you are very capable of understanding the code yourself, so would you be able to start trying that? Most of the back-end stuff is in locallib.php, and the method names are quite clear. Of course, if there is anything you can't work out yourself, please ask again. Thanks.
