Oracle数据库脚本学习：建用户、删用户、建表、改表、删表
一、Shell脚本：dbscore.sh
调用方法：
/bin/sh dbscore.sh create_all
/bin/sh dbscore.sh update_score
/bin/sh dbscore.sh drop_all
#!/bin/sh echo "$1" if [ "$1" == "create_all" ]; then echo Create User and Table... sqlplus / as sysdba @create_all.sql elif [ "$1" == "drop_all" ]; then echo Drop User and Table... sqlplus / as sysdba @drop_all.sql elif [ "$1" == "update_score" ]; then echo Update Score... sqlplus / as sysdba @update_score.sql fi
二、建用户、建表：create_all.sql
SET SERVEROUTPUT ON CREATE USER "TSYBIUS" IDENTIFIED BY "1234"; GRANT "DBA" TO "TSYBIUS"; CREATE TABLE TEST_SCORE ( StudentId number(10,0), StudentName varchar2(20), TestScore number(10,0), PRIMARY KEY(StudentId) ); INSERT INTO TEST_SCORE (StudentId, StudentName, TestScore) VALUES (0, 'Gaius', 70); INSERT INTO TEST_SCORE (StudentId, StudentName, TestScore) VALUES (1, 'Marcus', 57); INSERT INTO TEST_SCORE (StudentId, StudentName, TestScore) VALUES (2, 'Titus', 54); INSERT INTO TEST_SCORE (StudentId, StudentName, TestScore) VALUES (3, 'Quintus', 49); INSERT INTO TEST_SCORE (StudentId, StudentName, TestScore) VALUES (4, 'Verinus', 60); INSERT INTO TEST_SCORE (StudentId, StudentName, TestScore) VALUES (5, 'Rufus', 59); EXIT
三、将表中属性TestScore在[55,60)的值调整为60：update_score.sql
(就是把那些考试成绩和及格线差不到5分的学生分数提到及格，汗！)
SET SERVEROUTPUT ON
DECLARE
V_ID TEST_SCORE.StudentId%TYPE;
V_NAME TEST_SCORE.StudentName%TYPE;
V_SCORE TEST_SCORE.TestScore%TYPE;
CURSOR C IS SELECT StudentId, StudentName, TestScore FROM TEST_SCORE;
V_COUNTER NUMBER(15,0) :=0;
BEGIN
OPEN C;
LOOP
FETCH C INTO V_ID, V_NAME, V_SCORE;
EXIT WHEN C%NOTFOUND;
DBMS_OUTPUT.PUT_LINE('Checking Data: '||C%ROWCOUNT);
IF V_SCORE<60 AND V_SCORE>=55 THEN
UPDATE TEST_SCORE SET TestScore=60 WHERE StudentId=V_ID;
V_COUNTER:=V_COUNTER+1;
DBMS_OUTPUT.PUT_LINE(V_NAME||': Update Data!');
END IF;
END LOOP;
CLOSE C;
DBMS_OUTPUT.PUT_LINE('Total Update: '||V_COUNTER);
END;
/
EXIT
四、删用户、删表：drop_all.sql
DROP USER "TSYBIUS" CASCADE; DROP TABLE TEST_SCORE; EXIT
END
