Question

I have two large tables in a database. They both contain a column called “name”. My goal is to locate rows that contain names that are in one database but not the other.

I’m guessing there will be a join statement and a where, but I cannot figure out how to use the two in tandem in order to create a successful query.

Suggestions?

Answer 1

 SELECT * FROM TABLE_A WHERE NAME NOT IN 
   ( SELECT NAME FROM TABLE_B )
