Is possible this select?

hello

I have the following tables. The child table is subordinate to the main (with CodeOne key)

Principal
CodeOne (integer)

1
2
.
4
.

Secondary
CodeOne (integer) - CodeTwo (integer)

1 - 1
.....
4 - 7
4 - 9
.....

I need to select the main table records that meet the following condition in the child table, in the group of existing records for each CodeOne: (CodeTwo = x1 and CodeTwo = x2) or CodeTwo = x3.

For example: select CodeOne if [(CodeTwo = 7 and CodeTwo = 9) or CodeTwo = 3]. In this case CodeOne = 4 will be selected with data example (codes in red)

Is possible create that select and, if so, what would the syntax

Thanks in advance

select distinct CodeOne
from secondary s1
where CodeTwo=3 or (CodeTwo=7 and exists(select * from secondary s2 where s2.CodeOne=s1.CodeOne and s2.CodeTwo=9))

No, you're never too old to Yak'n'Roll if you're too young to die.

[code]
select CodeOne
from secondary
where codeTwo IN (3,4,7)
group by codeOne
having (min(codeTwo) = 3
AND min(codeTwo)=max(codeTwo))
OR (min(codeTwo) = 4
AND COUNT(DISTINCT codeTwo)=2)
[/code]
