If its already saved as a timestamp with timezone (or timestamp without timezone) in postgres, then date_trunc(‘day’, [field_name]) will do the trick.

Hello,

 

I have a table with a datetime field which saves (of course) date and time information. I need to design a query to count the number of records of each date without taking into account the time portion. I have seen that I can use functions like EXTRACT but I do not find how to extract the whole date only.

 

I will very much appreciate your feedback.

 

Respectfully,

Jorge Maldonado
