Thingworx 9.0 backups are not suits in Thingworx 9.1
Hi Everyone,
I have used Thingworx 8.5 then I have shifted all my backups in thingworx 9.0 it's fine and there is no issue with any entity but now when I have shifted all the Thingworx 9.0 backups into Thingworx 9.1.
It totally strange, some widgets that I have used in thingworx 9.0 mashups are gone.
I have used PostgreSQL queries in Thingworx 9.0 but after shifting backups in Thingworx 9.1 it's not running I haven't modified any query after shifting as it is I have shifted.
a select query is running in the database thing but not running JOINs query in the database things
Like above query is running but not running below types query i.e JOINs
mem.member_id,concat(us.first_name,' ',us.Last_name) as fullname,ci.city_name,us.is_active,mem.checkbox
FROM "tbl_members" AS mem
JOIN "tbl_users" AS us
ON mem.user_id = us.user_id
JOIN "tbl_user_info" AS ui
ON us.user_id = ui.user_id
JOIN "ref_cities" AS ci
ON ui.city_id = ci.city_id
error is below, I have used this same querry in PostgreSQL it is running but thingworx its NOT
Is it thingworx version problem?
I don't know what happened and what I have to do next please suggest the way.
