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/shecho "$1"if [ "$1" == "create_all" ]; thenecho Create User and Table...sqlplus / as sysdba @create_all.sqlelif [ "$1" == "drop_all" ]; thenecho Drop User and Table...sqlplus / as sysdba @drop_all.sqlelif [ "$1" == "update_score" ]; thenecho Update Score...sqlplus / as sysdba @update_score.sqlfi

二、建用户、建表：create_all.sql

SET SERVEROUTPUT ONCREATE 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 ONDECLAREV_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;BEGINOPEN C;LOOPFETCH 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 THENUPDATE 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
