Re: merging facilities (org-units) without losing data

 

Hi Moses,

You need to load both of those functions into your database.

1) Script to delete an orgunit is here
<https://github.com/dhis2/dhis2-utils/blob/master/resources/sql/delete_orgunit_with_data.sql>
2) Script to merge two orgunits is here
<https://github.com/dhis2/dhis2-utils/blob/master/resources/sql/merge_orgunits.sql>

After that, just call the function with

SELECT merge_organisationunits(source_uid,dest_uid ,strategy);

where `source_uid` is the UID of the organisation unit you want to get rid
of, `dest_uid` is the UID of the organisation unit you want to keep and
move data to
and `strategy` is one of the following:

SUM: Returns the sum of the values, when there is overlapping data.
MAX: Returns the max of the values, when there is overlapping data.
MIN: Returns the min of the values, when there is overlapping data.
AVG: Returns the mean of the values, when there is overlapping data.
LAST: Returns the last value entered, when there is overlapping data.
FIRST: Returns the first vale entered, when there is overlapping data.

Note that this only applies to numeric data. For other data (Boolean, text,
etc) which cannot be aggregated numerically, the last value will always be
taken.

The merge script will not handle situations where you have overlapping
tracker/event data, so you would need to figure out how to handle that
yourself!

Hope that helps to clarify and good luck!

Regards,
Jason Pickering
