I'll simplify to the following:
table1.BusinessName
table1.ID
tableA.RefID
tableA.comment
tableA has a many to one relation. table1.ID <-> tableA.RefId
Now the question.
#1 - I would like to identify every table1.BusinessName that doesn't have at least one tableA.comment that DOES NOT have *last update* in it.
How can this be done?
