Help writing a basic JOIN in Postgres -- 2

tableA
tableA.column1


tableB
tableB.column1
tableB.column2
tableB.column3
tableB.column4
tableB.column5
tableB.column6
tableB.column7
tableB.column8

I'd like to know which values from multiple columns in Table B that don't equal the values found in the single column in Table A.
