Falsche Syntax in der Nähe meines Alias ​​beim Verbinden von Unterabfragen?

Question

Mein Code ist unten angegeben. Ich erhalte die Fehler „Falsche Syntax nahe dem Schlüsselwort" OTB“(Linie 48) und „Falsche Syntax nahe dem Schlüsselwort ‚otb_ly‘“

Ich habe keine Ahnung, was das bedeuten könnte! Weil es für mich Sinn macht, meinen zwei Unterabfragen beizutreten (die ich otb und otb_ly genannt habe).

Für sich allein funktionieren die Unterabfragen gut.

declare @snapLY table (hotel_id tinyint, import_date date) 
insert into @snapLY select hotel_id, max(import_date) from [UKRMC].[dbo].[block_res]

Answer 1

Sie verpassen eine FROM auf der Linie 14:

... 
     --otb_ly.rn_LY as OTB_rn_LY 
FROM 
(
... 

Diese Abfrage in allen ehrlich, braucht eine massive Nacharbeiten ... Das ist wirklich schwer zu lesen.
