hi!
SELECT distinct a.EML_ADDRESS
from test.eml a, eml_addr_t b
where a.eml_address = b.eml_address(+)
and b.eml_address is null

seems to work. when i first did it without the null statement it returned values that existed in both tables. why do i have to search for nulls? i am confused about that.

thanks a million! Received on Mon May 09 2005 - 12:10:50 CDT
