Here is the problem (returns 0 rows):
select * from table1 t1 left join table2 t2 on

t2.date2 is null
where t2.name='Smith'
Here is the solution:
select * from table1 t1 left join table2
I would like to find the missing subset of rows in table2 based on the rows
in table1.
Normally it would look like this:
select * from table1 t1 left join table2 t2 on t1.date1=t2.date2 where
t2.date2 is null

table2 for
select * from table1 t1 left join table2 t2 on t1.date1=t2.date2 where
t2.date2 is null
where t2.name='Smith'
Maybe this?
select * from table1 t1 left join table2 t2 on t1.date1 = t2.date2 AND
t2.name = 'Smith' WHERE t2.date2 is null;
