Crystal Reports invoke Oracle stored procedures

Source: Internet
Author: User

Crystal Report version is 8.5

Stored procedures are:

create or replace package pkg_test4
as
type v_cursor is ref cursor;
end pkg_test4;
/
create or replace procedure pro_test4
(P_CURSOR in out pkg_test4.v_cursor)
as
sqlstr varchar2(3000);
begin
sqlstr :='select table_name from user_tables';
open p_cursor for sqlstr;
end pro_test4;
/

Crystal Report released to a Java application

Problem:

1, to return more than one record, you can only define stored procedures?

2. How to test stored procedures in Sqlplus?

3, in the Crystal Report can access the stored procedures, but after the release can not generate reports?
