Can normal sql statement check thru all occurance ?

Question

Hi ,
i have the following sample data
A)
select * from tt_test11 ;
        IDX1     CREATION_DATE
1     1     12/4/2006 11:00:23 AM
2     1     12/1/2006 11:00:23 AM
3     1     11/1/2006 11:00:23 AM
B)
select * from tt_test12
        IDX1     STARTTIME     ENDTIME
1     1     12/4/2006 10:00:23 AM     12/5/2006 1:00:23 AM
2     1     12/1/2006 10:00:23 AM     12/3/2006 1:00:23 AM
3     1     11/1/2006 10:00:23 AM     11/5/2006 1:00:23 AM
C)
select  * from tt_test11 a
where exists (select null from tt_test12 b
where a.idx1 = b.idx1
and a.creation_date not between b.starttime and b.endtime )
        IDX1     CREATION_DATE
1     1     12/4/2006 11:00:23 AM
2     1     12/1/2006 11:00:23 AM
3     1     11/1/2006 11:00:23 AMwhat i want to acheive :
i want to return all records from tt_test11 only when all records has been matched and there's no record that exists in the range from tt_test12
if seems that from part C , that it'll return a record as long as record from tt_test11 is not matched against a record in tt_test12
and i am now doing a function to check against all record in tt_test12 and return a flag to indicate whether the record from tt_test11 does not exist in tt_test12
but how can i do that in using SQL statements alone ?
pls advise
tks & rgds
