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
