Обсуждение: Detaching multiple partitions in 1 ALTER TABLE statement
Hi, I’m wondering what is the syntax for detaching multiple partitions in 1 ALTER TABLE statement. I’ve tried this: # ALTER TABLE movement_legs DETACH PARTITION movement_legs_2019_06_20_11_15, DETACH PARTITION movement_legs_2019_06_20_11_20; psql: ERROR: syntax error at or near "," LINE 1: ...gs DETACH PARTITION movement_legs_2019_06_20_11_15, DETACH P… The documentation suggests "DETACH PARTITION can be combined into a list of multiple alterations to be applied together”: https://www.postgresql.org/docs/12/sql-altertable.html But I haven’t found an example of where multiple partitions are detached in 1 statement. This is using version 12 beta 1. Many thanks, Ben

LINE 1: ...gs DETACH PARTITION movement_legs_2019_06_20_11_15, DETACH P…
The documentation suggests "DETACH PARTITION can be combined into a list of multiple alterations to be applied together”:
Docs say this" All the forms of ALTER TABLE that act on a single table, except RENAME , SET SCHEMA , ATTACH
PARTITION , and DETACH PARTITION can be combined into a list of multiple alterations to be
applied together."
PARTITION , and DETACH PARTITION can be combined into a list of multiple alterations to be
applied together."
Perhaps a comma would be helpful, but its clear that you can do multiple detaches in one command at present.
But it sounds like a great feature.
