Need to use Group By but only want to group some of the columns not all

Question

Hello all! I am having some issues here. I am rather new to SQL and I am getting stuck with grouping. I have the query below but I only want to group by these columns, instead of all the columns in my select statement.
ah.fund,
ah.dept,
ah.org,
ah.acct,
t.fund,
t.dept,
t.org,
t.acct
This will eventually go into Oracle reports builder. Is there any way I can archive this at all? The query will return all the t for a given time period, but they need to be grouped by the fully qualified account number which consists of the fund, dept, org and acct columns.
Thanks in advance!

Answer 1

In reports builder you can group the columns without having to group it in your query. It is also known as the break report which contains multiple groups in its data model.
