ORACLE 包内的存储过程的动态sql

--

---创建包

create or replace package test_pkg is

g_public_flag varchar2(1);

function test_function(p_param1 varchar2,

p_param2 varchar2) return varchar2;

function hello_function(p_param3 varchar2) return varchar2;

procedure ff(p1 varchar2);

end;

--包体

create or replace package body test_pkg is

g_private_flag varchar2(1) := 'Y';

function test_function(p_param1 varchar2,

p_param2 varchar2) return varchar2

is

val varchar2(10):='hello';

begin

dbms_output.put_line('helo');

return val;

end ;

function hello_function(p_param3 varchar2) --参数与包头中必须保持一致

return varchar2 is

val varchar2(10):='hello';

begin

dbms_output.put_line('world');

return val;

end;

procedure ff(p1 varchar2) is

flag number;

pp1 VARCHAR2(10):='p';

p2 VARCHAR2(10):='p';

p3 VARCHAR2(10):='p';

p4 VARCHAR2(10):='p';

begin

select count(*)into flag from all_all_tables where table_name='LOGTABLE1';

dbms_output.put_line(flag);

if(flag = 0) then

execute immediate

'CREATE TABLE logtable1 (userid VARCHAR2(10), logdate VARCHAR2(10),exception_id VARCHAR2(10),exception_msg VARCHAR2(10))';

end if;

execute immediate 'insert into logtable1 values (:1,:2,:3,:4)' using '1','1','2','3'; --只能动态插入

end;

end;

----测试

declare

begin

dbms_output.put_line(test_pkg.test_function('1','1'));

dbms_output.put_line(test_pkg.hello_function('1'));

test_pkg.ff('dd');

end;

select * from logtable1;

drop table logtable1
