Question

我在包中有一个带有OUT参数的sql过程。包装体如下所示

create or replace
PACKAGE BODY TEST_PACKAGE AS  -- body
   Procedure            TEST_PROCEDURE (
       data_1       IN        VARCHAR2
,      data_2       IN        VARCHAR2
,      data_3       IN        DATE
,      out_data     OUT       VARCHAR2 )
IS
   BEGIN
       INSERT INTO TEST_TABLE(
  COLUMN_1,
  COLUMN_2,
  COLUMN_3) VALUES(
  data_1,
  data_2,
  data_3
  );
  out_data:='SUCCESS';
End TEST_PROCEDURE;
END TEST_PACKAGE;

我尝试使用下面的SQL命令调用此过程。

DECLARE
sample_out_data VARCHAR2(100);
Begin
TEST_PACKAGE.TEST_PROCEDURE ('test_data_1','test_data_2',2012-02-23,sample_out_data);
END;

但它给了我错误。谁能告诉我如何调用此程序？

错误如下所示

Error starting at line 13 in command:
Declare
sample_out_data VARCHAR2(100);
Begin
TEST_PACKAGE.TEST_PROCEDURE ('test_1','test_2',2012-02-23,sample_out_data);
End;
Error report:

create or replace
   Procedure            TEST_PROCEDURE (
       id           IN        number
,      price        IN        long
,      date_req     IN      timestamp
,      out_status   OUT     varchar2
 )
IS
   BEGIN
       INSERT INTO orders(
  id,
  price,
  date_req) VALUES(
  id,
  price,
  date_req  );
out_status:='SUCESS';
 End TEST_PROCEDURE;

输出

DECLARE
SUCCESS VARCHAR2(100);
begin
TEST_PROCEDURE(10,1456,'11-NOV-13 12.42.53.658439 PM',SUCCESS);
DBMS_OUTPUT.PUT_LINE('THE STATUS IS'||' '||SUCCESS);
end;

如何调用具有OUT值的包中的过程？
