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 varcha

—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本文来源[email protected]搞@^&代*@码)网5 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
