oracle 存儲過程的基本語法
1.基本結(jié)構(gòu)
CREATE OR REPLACE PROCEDURE 存儲過程名字
(
參數(shù)1 IN NUMBER,
參數(shù)2 IN NUMBER
) IS
變量1 INTEGER :=0;
變量2 DATE;
BEGIN
END 存儲過程名字
2.SELECT INTO STATEMENT
將select查詢的結(jié)果存入到變量中，可以同時將多個列存儲多個變量中，必須有一條
記錄，否則拋出異常(如果沒有記錄拋出NO_DATA_FOUND)
例子：
BEGIN
SELECT col1,col2 into 變量1,變量2 FROM typestruct where xxx;
EXCEPTION
WHEN NO_DATA_FOUND THEN
xxxx;
END;
...
3.IF 判斷
IF V_TEST=1 THEN
BEGIN
do something
END;
END IF;
4.while 循環(huán)
WHILE V_TEST=1 LOOP
BEGIN
XXXX
END;
END LOOP;
5.變量賦值
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.帶參數(shù)的cursor
CURSOR C_USER(C_ID NUMBER) IS SELECT NAME FROM USER WHERE TYPEID=C_ID;
OPEN C_USER(變量值);
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
連接數(shù)據(jù)庫后建立一個Test WINDOW
在窗口輸入調(diào)用SP的代碼,F9開始debug,CTRL+N單步調(diào)試
