SELECT a.*, 'Label' AS field_alias 
FROM Table_A a 
WHERE NOT EXISTS (
	SELECT 1 
	FROM Table_B b 
	WHERE a.[Field_1] = b.[Field_1] AND a.[Field_2] = b.[Field_2]) 
AND EXISTS (
	SELECT [Field_2] 
	FROM Table_B) 
AND [Field_3] LIKE '%string_wildcard%'

Hello, I am interested in translating the above SQL logic into a Alteryx workflow. I am new to Alteryx, and would greatly appreciate any insight or guidance. 

What I've Learned

From other community discussions, I believe that using a Join Tool could be used to replicate WHERE NOT EXISTS  and EXISTS, but I am not sure how to use both in the same workflow.

Additionally, I am interested in using a wildcard functionality to return records where a certain field's value is LIKE a specified string.

The Data

Two tables with the same 5 field names from different periods.

Refer to below, it should contain all you need for SQL Joints and Alteryx Join.
And as for the wild card, you could use Contain Function or Reg_Match function.
