Problem with plsql block

Question

Hello All,
I have a sql query which i am trying to put it in plsql block.It throws me an error saying i cannot have group function as my two select strings gives me more than one row. How to tackle this??
declare
uuid varchar;
stat_date date;
begin
select 'I'||Lower(docfamily_uuid) into uuid, max(status_date) into stat_date from document_status where status_code=303 or status_code=305 group by docfamily_uuid;
end;
Thanks

In addition to being mal-formed it is likely your problem stems from the fact that your query is returning more than one row. Now perhaps you are expecting only one row and your GROUP BY might be getting in the way. Try changing your GROUP BY to include the LOWER function that is in your SELECT statement. But realize that this in itself will not guarentee one row returning from the SELECT statement.
WITH document_status AS
SELECT 'xxx' docfamily_uuid, sysdate status_date, 303 status_code from dual
UNION ALL
SELECT 'XXX' docfamily_uuid, sysdate status_date, 303 status_code from dual
SELECT 'I'||Lower(docfamily_uuid), max(status_date)
FROM   document_status
WHERE  status_code=303 or status_code=305
GROUP BY docfamily_uuid;
