Again look at the others write code, don't understand the following statement: the WHEN '(' +') THEN IN is stem what of, this sentence is not a constant set up? What's behind it?

 SELECT 
* 
The FROM 
Credentials table 
WHERE 
Year='2018' 
AND 1=(
CASE 
WHEN '(' +') THEN IN 1 
ELSE (CASE WHEN subject code (' ') THEN one ELSE 0 IN END) 
END 
) 

[/code]
