I have a query that is similar to the one below.  I am trying to get all the records from tableA but the where clause is removing the records. I want the records that do not exists in the table b to be null.
select max(cola)

from tableA

left join tableB on tableB.colB = tableA.colB

where tableA.colA<table.colB

group by tableA.colA
