Oracle ORA-01422: exact fetch returns more than requested number of rows

Question

I am trying to create a member function that returns the member names of expired members. My select query works outside of the member function and this member function compiles with no problems but when I call the function I get this error:

ORA-01422: exact fetch returns more than requested number of rows

I assume it is something simple but I have not been using Oracle for long so got a bit stuck with syntax. Can anyone help with this?

Answer 1

Since this query can return more than one row you need to use a cursor and a cursor-for loop to iterate over results. However you cannot return more than one member name using a varchar; you could use a PL-SQL table.

Answer 2

select m.forename into memberName from member_tab m where ADD_MONTHS(m.datejoined, 64) < SYSDATE;

looks like this query is returning more than 1 results ...

u can use a select count(*) or exception handling to address the exception and handle >1 results
