There was a breaking change between P and Q, where certain fields in queries need to be fixed in order to make the lists editable
This script updates lists to account for this change. It is only needed if lists were created in Poppy that use any of the "ID" fields listed below
in the "mappings" CTE
Is this necessary?
Run this query to determine if any lists in a tenant are impacted (make sure to set the tenant ID first!).
| Code Block | ||

-- Replace <tenant ID> with the relevant tenant ID here!
SET search_path TO '<tenant ID>_mod_lists', public;
SELECT *
FROM list_details
WHERE fql_query ~* '\m(item_level_call_number_typeid|item_effective_call_number_typeid|item_effective_library_id|item_effective_location_id|item_material_type_id|item_permanent_location_id|item_temporary_location_id|item_material_type_id|loan_checkin_servicepoint_id|loan_checkout_servicepoint_id|loan_policy_id|user_patron_group_id)\M' |
Usage
Set the tenant ID in the search path, below
Run the script. This should only take a few seconds
...
If you get an error with gen_random_uuid(), run this, then try again:SET search_path TO public; CREATE EXTENSION IF NOT EXISTS "uuid-ossp";
