Transaction type SQL help

Question

I have a table with columns type, account,date.Type is the transaction type. Type has data from 1 to 10.
Now i want all the transactions, but if on a particular day there is type 2 & 4 for a particular account then i don't want to retrieve those transactions.
For example on 10th July an Account 100123 has both types 2 & 4. When i do select all i don't want to retrieve both those rows. Please help me with some idea.
EDIT: Actually on a given if there is a type =2 followed by any other types(4,6,3,8.....any) we don't want both of those transactions. On a particular day if there is just type =2 alone we don't want that also.
So basically on a given day we don't want to have type =2.

Answer 1

If you mean :
When in a day there is some lines with type 2 or 4 then do not retrieve rows from that day even those with type not equal to 2 or 4, then I would try :select *
from table t
where not exists (
select null from table t2
where trunc(t.transaction_date)=trunc(t2.transaction_date) and t2.transaction_type=2
and not exists (
select null from table t3
where trunc(t.transaction_date)=trunc(t3.transaction_date) and t3.transaction_type=4
);or maybe :select *
from table t
where not exists (
select null from table t2
where trunc(t.transaction_date)=trunc(t2.transaction_date) and t2.transaction_type in (2,4)
);Edited by: Nicosa on Jul 18, 2011 6:40 PM
