初学者请教一个很简单的存储过程
CREATE   OR   REPLACE   PROCEDURE   USP_Query_Add_PO  

(in_User_ID   NVARCHAR2)

BEGIN
  DELETE   FROM   T_PO_MASTER_TEMP   WHERE   USER_ID   =   in_User_ID;
 
  SELECT   TPMT.PO_NUMBER,TL.PO_TYPE   AS         TYPE,TPMT.CREATE_DATE,TPMT.CUSTOMER_PO_NUMBER, 'Add   detail '   AS   dlink  
  FROM   T_PO_MASTER_TEMP   TPMT,T_LOOKUP   TL  
  WHERE   TPMT.TYPE_ID   =   TL.LOOKUP_ID
  USER_ID   =   in_User_ID;
 
END   USP_Query_Add_PO;


报错啊,什么缺少into,请教了

oracle 存储过程的基本语法
1.基本结构
CREATE OR REPLACE PROCEDURE 存储过程名字
(
参数1 IN NUMBER,
参数2 IN NUMBER
) IS
变量1 INTEGER :=0;
变量2 DATE;
BEGIN
END 存储过程名字
2.SELECT INTO STATEMENT
将select查询的结果存入到变量中,可以同时将多个列存储多个变量中,必须有一条
记录,否则抛出异常(如果没有记录抛出NO_DATA_FOUND)
例子:
BEGIN
SELECT col1,col2 into 变量1,变量2 FROM typestruct where xxx;
EXCEPTION
WHEN NO_DATA_FOUND THEN
xxxx;
END;
...
3.IF 判断
IF V_TEST=1 THEN
BEGIN
do something
END;
END IF;
4.while 循环
WHILE V_TEST=1 LOOP
BEGIN
XXXX
END;
END LOOP;
5.变量赋值
V_TEST := 123;
6.用for in 使用cursor
...
IS
CURSOR cur IS SELECT * FROM xxx;
BEGIN
FOR cur_result in cur LOOP
BEGIN
V_SUM :=cur_result.列名1+cur_result.列名2
END;
END LOOP;
END;
7.带参数的cursor
CURSOR C_USER(C_ID NUMBER) IS SELECT NAME FROM USER WHERE TYPEID=C_ID;
OPEN C_USER(变量值);
LOOP
FETCH C_USER INTO V_NAME;
EXIT FETCH C_USER%NOTFOUND;
do something
END LOOP;
CLOSE C_USER;
8.用pl/sql developer debug
连接数据库后建立一个Test WINDOW
在窗口输入调用SP的代码,F9开始debug,CTRL+N单步调试

TL.PO_TYPE AS TYPE是关键字吧
