Solution 2

You have two ways to do this

SQL

Select B.* FROM B
LEFT JOIN A ON A.ID = B.ID
LEFT JOIN C ON C.Column_name = B.Column_name
Where A.ID IS NULL

The Other is

SQL

Select B.* FRom B
LEFT JOIN C ON C.Column_name = B.Column_name
where B.ID NOT IN (SElect A.ID From A)

*Column_name means you need to give column name you are willing to do between B and C
