Get month name from number in PostgreSQL

Question

I have a table with a column month(integer). In this column I store values like 1, 2, .. 12.
But I have to show the month name

Answer 1

Basically what @small_duck already posted, but a couple of improvements:

SELECT to_char(to_timestamp (4::text, 'MM'), 'TMmon')

• A plain cast to text 4::text is enough, no need for to_char(..).

• Question asks for lower case "jan", there is a template pattern for that: mon.

• If you want to localize the output, prefix the template with the modifier TM.
