[Qgis-user] Numbering Fields by custom squence

[st_kiefer at web.de]

Hi,

first idea could be something like this:

concat('OBST',lpad(to_string($id), 4, '0'))

if you don't need concrete values. You might also add an offset to $id.

concat('OBS',lpad(to_string($id + <offset>), 4, '0'))

Hope that helps.

Regards.


Stefan
