ora-00902 invalid data type

Yes, I tried your solution. It is erroring out near OVER (line 34).

True, it is a very old version. But, I can't help it. I have no control over it. I can execute this function just fine in Oracle 9i and above. But, not in in 8.1.6. I was wondering if there is any other way of achieving this. Thanks,

Oh! dear,

Over isn't supported in Oracle 8.

Really bad.

So, we have to explore some different ares to achieve the same.

It is working in Oracle 9i.

Regards.

There are all sorts of problems with this because of this version.

I can't even use Oracle SQLDeveloper to connect. Other pl/sql developing tools don't work right either. Even if they do for couple of day, they eventually giveup.

First you can test this code ->

create type np is table of number;
  2  / Type created. 
SQL> ed
Wrote file afiedt.buf   
1     Create or Replace Procedure myProc(myArray np)
2      is   
3      i   number(10);   
4      rec emp%rowtype;   
5      Begin   
6         for i in 1..myArray.count   
7         loop   
8           select *   
9           into rec  
10           from emp  
11           where empno = myArray(i);  
12        dbms_output.put_line('Employee No:'||rec.empno||' Name:'||rec.ename);  
13        end loop;  
14*   End myProc;  
15  /
Procedure created. 

SQL> declare
  2      v np:=np(6666,7777);   
  3  begin   
  4    myProc(v);   
  5  end;   
  6  / 
  Employee No:6666 Name:prithwi 
  Employee No:7777 Name:Avik

If collection is working in 8 then you can implement that in your code.

Oh! dear.

I was completely overlooked it. It is a function and op is returning in form of ref cursor.

Good point.

It works from sqlplus this way. But, we need to call this function from java code. I am not sure if creating a variable and printing it would work from java call. Will it work?

Of course not, as has been mentioned by SomeoneElse earlier in this thread. You have been asking for a SQL*Plus solution since the get-go:

user6773 wrote:
Hello all -

I have a function that returns a ref cursor.

When I test this function using PL/SQL developer, it works just fine and returns ref cursor with a set of price values for a set of products.

However, when I test the same function from SQL*Plus, it errors out.

select get_price('0123','p1,p2,p3') from dual;

Error at line 1:
ORA-00902: invalid datatype

Could you please help me out. Thanks in advance.

and all the suggestions over here are for SQL*Plus.

This is not a java forum. This is a SQL and PL/SQL forum. If you are expecting someone to post a Java/JDBC program to help you out, then you are barking up the wrong tree.

You may want to check out the appropriate forum for a java solution.

Here is another way to print the value from ref cursor without using the print statement and that might be helpful for you in your Java ->
