Very briefly, the core tables for aggregate data include datavalue, organisationunit, period, and dataelement.
Tables are linked on ids, e.g. organisatoinunitid. There are also some very helpful tables starting with underscore _.

We do not have extensive documentation directly for the DB schema. You will have to browse the schema of an instance using a tool of your choosing (pgAdmin, psql). For metadata the source Java beans and Hibernate mappings (*.hbm.xml) might also be useful to understand the relations (especially for meta data). It’s all pretty standard stuff, though, so it’s not hard to figure out for simple use cases like the one you mentioned (see Jason’s example query).

Hi Tantely,
Standard ANSI SQL can be executed easily with-in Sqlviews sub-module in DHIS2. The link below should be helpful.

Hi Raminosa,
I think you should try to install Postgres locally on your laptop, which would allow you to easily query the database using PgAdmin.

Hi All,
I am looking for a documentation of the use of the SQL syntax to run in SQL View (table names, field names specific to DHIS2 ). I have seen for example to query organization unit, we have to select from “ou” or to use “dv” to select the datavalues. I am planning to list all the uid, code and names of all organization units at all levels (1 to 6) in one single query result.
Thank you for your support.
Tantely.
