Oracle编写带数组参数的存储过程

--功能：采用存储过程、type组合来实现批量操作，以节省系统开销，提高效率。 
     
--创建 Type bodies 
CREATE OR REPLACE TYPE TYPE_ARRAY AS OBJECT 
( 
  ID    NUMBER(10), 
  REMARK VARCHAR2(10) 
) 
--创建 Types 
CREATE OR REPLACE TYPE TYPE_ARRAY_TBL AS TABLE OF TYPE_ARRAY 
--创建表 
CREATE TABLE T_TEMP(ID NUMBER(10) NOT NULL, REMARK NUMBER(10)) 
--创建存储过程 
 CREATE OR REPLACE PROCEDURE PROC_ARRAY_PARAM(TYPE_OBJECT IN TYPE_ARRAY_TBL) IS
   
 BEGIN
  INSERT INTO T_TEMP
    (ID, REMARK)
    SELECT ID, REMARK
      FROM THE (SELECT CAST(TYPE_OBJECT AS TYPE_ARRAY_TBL) FROM DUAL);
   
  FOR I IN 1 .. TYPE_OBJECT.COUNT LOOP
    DELETE FROM T_TEMP WHERE ID = TO_NUMBER(TYPE_OBJECT(I));
  END LOOP;
  COMMIT;
 END;
   
 END PROC_ARRAY_PARAM;

--创建包 
CREATE OR REPLACE PACKAGE PKG_PARAM AS 
  TYPE ARRAY_PARAMS IS TABLE OF VARCHAR2(20) INDEX BY BINARY_INTEGER; --先定义包，这个就相当于一个数组 
  PROCEDURE PROC_PARAM(PARAMS IN ARRAY_PARAMS); 
END PKG_PARAM; 
--创建包体 
CREATE OR REPLACE PACKAGE BODY PKG_PARAM AS 
  PROCEDURE PROC_PARAM(PARAMS IN ARRAY_PARAMS) AS 
    I NUMBER := 1; --这个可以不写 
  BEGIN 
    SAVEPOINT SP1; 
    FOR I IN 1 .. PARAMS.COUNT LOOP 
      DELETE FROM T_TEMP WHERE ID = TO_NUMBER(PARAMS(I)); 
    END LOOP; 
    COMMIT; 
  EXCEPTION 
    WHEN OTHERS THEN 
      ROLLBACK TO SAVEPOINT SP1; 
  END PROC_PARAM; 
END PKG_PARAM;
