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
