Dear Faqir

Maybe you could install the latest develop version from sources
https://github.com/MobilityDB/MobilityDB#building--installation
instead of using docker image. This is the version that will be used for the official 1.0 release in the forthcoming days.

test=# SELECT duration(period '[2012-01-01, 2012-01-03)');
 duration
----------
 2 days
(1 row)

Regards

Esteban

Dear Recipient!

I hope this mail finds you in good health and enjoying your life.



I am Faqir Hussain, an MS student at National University of Sciences and Technology. I am working on MobilityDB as my research work of MS. I am quite new to this platform. Previously I have worked on MS SQL Server and PostgreSQL. I have gone through some of its stuff including Research Papers, Tutorial Videos etc. Right now, I have prepared my machine to work on MobilityDB using Docker Desktop (as per instructions available on https://github.com/MobilityDB/MobilityDB-docker). I have installed two version of MobilityDB:



  1.  MobilityDB Latest
  2.  MobilityDB Berlin Mode (codewit/mobilitydb)



Both are working here, but I found some of the issues like:



SELECT duration(period '[2012-01-01, 2012-01-03)');



This query produces error on both versions as given below:



ERROR: function duration(period) does not exist LINE 1: SELECT duration(period '[2012-01-01, 2012-01-03)'); ^ HINT: No function matches the given name and argument types. You might need to add explicit type casts. SQL state: 42883 Character: 8



I would request to guide me how to resolve it.







With regards,
