Doug Kline explains the ANY and ALL operators in SQL:
-- note that this creates a single column of values
-- which could be used in something like IN
-- for example
SELECT 1
WHERE 12 IN ( SELECT tempField
FROM (VALUES(11),(12),(7)) tempTable(tempField))
-- I could rephrase this as:
SELECT 1
WHERE 12 = ANY ( SELECT tempField
FROM (VALUES(11),(12),(7)) tempTable(tempField))
I rarely see these operators in the wild and might have used them in production code a couple of times if that.
