So ,basically, you want to have all values from the table a and matching
values (if they exist) from table b? How does this work for you:
select
Table1.val,
5 as CriteriaValue, ---probably variable...
OtherTable.id,
OtherTable.Text
from
Table1
left join OtherTable on table1.val = OtherTable.a and OtherTable.b = 5
Now, if this query works, you can delete all values from OtherTable that
have a value b = 5 and id not in the select. You can insert the rows
returned by query if you add filter WHERE otherTable.ID is null.
If this doesnt work for you, please elaborate...
