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
