Type body created with compilation error - oracle

Question

customer_ty object I have created has a nested table including
CREATE TYPE deposit_ty as object(
depNo number,
depCategory ref depcategory_ty,
amount number,
period number
)
/
CREATE TYPE deposit_tbl as table of deposit_ty
/
CREATE TYPE customer_ty as object(
custId varchar2(4),
custName varchar2(10),
address address_ty,
dob date,
deposits deposit_tbl
)
/
I have written a code to compute the total amount deposited by each client. Here is the code I've written;
alter type customer_ty
add member function totDeposits return number cascade
/
create or replace type body customer_ty as
member function totDeposits
return number is
total number;
BEGIN
select sum(d.amount) into total
from table(self.deposits) d;
group by self.custId,self.custName
return total;
END totDeposits;
END;
/
But I get a warning saying that the "type body created with compilation errors". What can I do to get rid of this?

Answer 1

If you do show errors immediately after you get the 'created with compilation errors' message, you'll see something like:
LINE/COL ERROR
-------- ------------------------------------------------------------------------------
8/5 PLS-00103: Encountered the symbol "GROUP" when expecting one of the following:
You can also query the user_errors or all_errors view to see the outstanding errors against any PL/SQL objects.
In this case it's a simple typo; you have the semicolon in the wrong place; instead of:
select sum(d.amount) into total
from table(self.deposits) d;
group by self.custId,self.custName
it should be:
select sum(d.amount) into total
from table(self.deposits) d
group by self.custId,self.custName;
In your version the ... d; is terminating that SQL statement - which would be invalid now because that truncated statement doesn't have a group by clause; but it doesn't get as far as complaining about that because it sees the group by ... as a separate statement, and that isn't the start of anything PL/SQL recognises as a query, statement, control loop etc., so it gives up.
