问题 I am struggling with a great challenge of a query. I have two tables, first has Tb1 drID schedDate rteID Second has: Tb2 drID FName LName Active Tb1 drID must be checked for Null or blank and match on schedDate and drID can not have any values that match Tb2.drID for date selected, checking for Null and '' essentially do this.
