The stored procedure in the oracle package returns the result set

The stored procedure in the ORACEL package needs to define a cursor variable in the package to return the result set, and the stored procedure uses this variable to return the result set.
Examples are as follows:

Bag

create or replace package TEST_PACKAGE is
  
  TYPE MY_CURSOR IS REF CURSOR;
  procedure Account_Check(
                          Comp      varchar,                  --公司号
                          ret out MY_CURSOR
                          );

end TEST_PACKAGE;

Inclusion

create or replace package body TEST_PACKAGE is

 procedure Account_Check(
                         Comp      varchar,                  --公司号
                         ret out MY_CURSOR  
                        )
                       as
  
   open ret for SELECT * FROM XXX;
 end ;
end TEST_PACKAGE;
