oracle存储过程---创建存储过程语句

一、创建存储过程语句

      语法:  CREATE OR REPLACE PROCEDURE testname( argument1 TYPE1, ....  ) AS BEGIN ...... END   testname

      例子:

CREATE OR REPLACE PROCEDURE test_name(
arg1 VARCHAR2,arg2 number,arg3 number)
AS
BEGIN
  insert into test_for_insert(
              STACID,  LOANNO,  SYSTID,  PARA1, PARA2 
            )values(
                       1,       arg1,       'wld',     arg2,    arg3
            );
        
  dbms_output.put_line('work!');
END test_name;

     右键‘测试’，输入参数

二、存储过程使用游标

       游标就像循环里面的指针

       语法：定义 :  CURSOR  point  IS SELECT number FROM test_table;  

                  使用：FOR  test_point  IN  point LOOP

                                  .................................

                             END LOOP;

create or replace procedure test1 (sys in varchar2)is
  v_sys  test_table.SYSTID%TYPE;
  v_arg number(10,2);
  CURSOR table_cursor IS
  SELECT SYSTID, NUMBER from test_table;  
begin    

  for test_cursor in table_cursor LOOP 
    if sys = 'TEST' then
     dbms_output.put_line(' work ');
   end if;
  END LOOP;
end test1; 

三、给变量赋值

         语法  :   SELECT  a.number, a INTO varible1 FROM test_table a;

         例子 ： 

create or replace procedure test_pro(sys in varchar2) is 

  v_sys  test_table.SYSTID%TYPE;
  v_varible1 number(10,2);
  v_varible2 number(10,2);

  CURSOR test_cursor IS
  SELECT SYSTID, NUMBER 
  from test_table;  

BEGIN

 for v_cursor in test_cursor LOOP
   if sys = 'wld' then
        select t.SYSTID, nvl(sum(t.var1+t.var2),0) 
        into v_sys, v_varible1
        from test_table t where  t.NUMBER = v_cursor.NUMBER;
       dbms_output.put_line('SYS : ' || v_sys || ' v_varible1  : ' || v_varible1 );
   end if;
 END LOOP;
END test_pro;

四、 插入表格

        语法: INSERT INTO table1 ( arg1, arg2 .....) SELECT varible1, varible2 ..... FROM table2;

        例子：

   

create or replace procedure test3 (sys in varchar2)is
  v_sys  test_table.SYSTID%TYPE;
  v_arg number(10,2);

begin    

    INSERT INTO table1
   (
    arg1, arg2, ....
    )
    select 
    varible1, varible2,...     
    from table2;
    
end test3;
