IBM认证数据库考试试题

IBM认证数据库考试试题IBM认证数据库考试试题IBM的历史可以追溯到电子计算机发展前的几十年，在电子计算机发展之前，它经营穿孔卡片数据处理设备。

下面是店铺整理的关于IBM认证数据库考试试题，欢迎大家参考!(1)已知表T1中有2行数据，T2中有3行数据，执行SQL语句“select a.* from T1 a,T2 b”后，返回的行数为______A、2行B、3行C、5行D、6行多表查询没有指定连接条件，会导致笛卡尔积的出现，返回行数等于2张表的行数乘积，返回6行记录考察：对多表连接、笛卡尔积的理解答案：A(2)、已知表T1和T2的字段定义完全相同，T1,T2中各有5条不同的数据，其中T1有2条数据存在于表T2中，语句“select * from T1 union select * from T2”返回的行数为_______A、8行B、10行C、3行D、12行第二题? UNION在进行表链接后会筛选掉重复的`记录，所以在表链接后会对所产生的结果集进行排序运算，删除重复的记录再返回结果。

考察：UNION 的理解答案: A(3)、已知表T1含有字段ID、CourseID和Score,且数据为ID CourseID Score3 1 902 1 852 2 903 2 80则语句“select id,sum(ScorE) from T1 group by ID”的执行结果为_________A、 ID sum(ScorE)—– ? ———-3 ? 1702 ? 175B、 ID sum(ScorE)—– ? ———-2 ? 1753 ? 170C、 ID sum(ScorE)—– ? ———-2 ? 1703 ? 175D、 ID sum(ScorE)—– ? ———-3 ? 1752 170第三题 GROUP BY 对按照ID字段进行分组，同时对ID相同字段的ScorE进行求和，GROUP by 会自动对结果集进行排序所以答案选B考察：group by 的理解答案: B(4)、电话号码表t_phonebook中含有100万条数据，其中号码字段PhoneNo上创建了唯一索引，且电话号码全部由数字组成，要统计号码头为321的电话号码的数量，下面写法执行速度最慢的是_________A、select count(*) from t_phonebook where phoneno >= ‘321’ and phoneno < ‘321A’B、select count(*) from t_phonebook where phoneno like ‘321%’C、select count(*) from t_phonebook where substring(phoneno,1,3) = ‘321’A>或者<操作符会采用索引查找B:LIKE通配符在XXX%情况下会应用索引，如果在%xxx%等情况下不会应用索引答案: C:采用函数处理的字段不能利用索引，例如substr()? 这个题好像写成java的函数了答案: C(5)、已知表tbl中字段land_ID建有索引，字段cust_id建有唯一索引，下列语句查询逻辑相同，其中执行效率最优的是A、 SELECT * FROM tblWHERE land_id > 750or (cust_id=180 or cust_id=560)B、 SELECT * FROM tblWHERE (cust_id=180 or cust_id=560)or land_id > 750C、 SELECT * FROM tbl WHERE land_id > 750UNIONSELECT * FROM tbl WHERE cust_id = 180UNIONSELECT * FROM tbl WHERE cust_id = 560D、 SELECT * FROM tbl WHERE land_id > 750UNION( SELECT * FROM tbl WHERE cust_id = 180UNION ALLSELECT * FROM tbl WHERE cust_id = 560)C/D相比较而言，D的执行效率更高一些UNION在进行表链接后会筛选掉重复的记录，所以在表链接后会对所产生的结果集进行排序运算，删除重复的记录再返回结果。

IBM笔试题

IBM笔试题（一）IBM笔试题第一部分：IPA T (IPA T 的全称是Information Processing Aptitude Test)。

PartI 15min 15Ques 矩阵排列PartII 4min 20Ques 数列猜测PartIII 5min （不记得多少题）Ques 数学计算PartIV 15min 15Ques 矩阵排列每部分单独发卷，卷子第一页是样板题。

没说开始考试，不让翻页。

时间到了就收走卷子，但是IPA T的答题卡是在最后所有答完再收。

答题方法，选哪个就在哪个地方画叉，一共有ABCDE五个选项。

题型和网上历年的题目一样，稍后做了一个总结。

记分方法：I和IV打错不扣分，II和III打错倒扣分第二部分：技术卷，答题时间是一个小时，有ABC三套卷子。

熟悉JA V A的选做AC，熟悉C++的选做BC。

题型为单选和多选，每题分值不同，做错不扣分，多选选不全得一半分。

我答的是BC卷，B卷全考C++，多为读程序选结果，类，字符串，指针之类的。

C卷什么都考，很细，UML、数据结构。

ibm面试题及答案

ibm面试题及答案在求职过程中，面试通常是每个求职者必须面对的挑战之一。

IBM作为一家全球知名的IT公司，其面试过程也被广大求职者所关注。

本文将介绍一些常见的IBM面试题，并提供相应的答案，帮助读者更好地准备和应对IBM面试。

一、自我介绍类1. 请简单介绍一下你自己。

答：首先，感谢面试官给我这次机会。

我叫XXX，毕业于XXX大学，专业是XXX。

我对计算机科学非常感兴趣，并在大学期间取得了优异的学业成绩。

我曾在实习期间参与了一个软件开发项目，这让我对软件开发有了更深入的理解和经验。

我热爱编程，具备良好的团队合作能力，并且能够快速学习适应新的技术和工作环境。

2. 你在过去的项目中遇到过什么难题，你是如何解决的？答：在过去的一个项目中，我们的团队遇到了一个性能瓶颈的问题。

经过分析，我发现问题是由于代码中的一处低效算法导致的。

为了解决这个问题，我首先进行了性能测试，并使用性能分析工具定位到问题的具体位置。

然后，我重写了相应的代码，改用更高效的算法，并对其进行了测试和验证。

最终，我们成功地解决了这个性能问题，并大大提升了系统的整体性能。

二、技术问题类1. 请谈谈你对面向对象编程的理解。

答：面向对象编程是一种软件开发的方法论，它将数据以及对数据的操作封装成对象，通过对象之间的交互来完成程序的功能。

面向对象编程的核心概念有封装、继承和多态。

封装可以隐藏对象内部的细节，提供公共的接口供其他对象使用；继承可以定义对象之间的层次关系，实现代码的复用；多态可以根据对象的具体类型执行不同的操作。

面向对象编程具有代码的可维护性、可扩展性和可重用性等优点，广泛应用于软件开发领域。

2. 请解释一下什么是数据库事务。

答：数据库事务是指一组对数据库的操作，这些操作要么全部执行成功，要么全部执行失败。

事务具有四个特性，即原子性（atomicity）、一致性（consistency）、隔离性（isolation）和持久性（durability）。

IBM笔试

IPAT 的全称是IBM Personal Aptitude Test，即IBM 个人能力测试。

这是IBM 招募新员工的笔试，考查英文阅读速度和基本运算反应能力。

这个与pg的pst要难很多，毕竟是电脑公司，不只是算算帐那么简单。

第一部分数据处理（矩阵变换）13分钟15题，答错不扣分第二部分数据分析（数字推测）4分钟20题答错扣分1/4的分第三部分名字忘了（应用题）12分钟15题答错扣分1/4的分第四部分和第一部分一样13分钟15题，答错不扣分一共是65题。

最关键的原则：1.保持冷静 2.敢于放弃 3.善于估算1.保持冷静可以肯定的说，没有人能把这四部分都按时答完。

公司考察的就是你在高压下能不能够保持冷静的思维。

我第一部分刚答完2/3就收卷了，卡还没涂呢，完全措手不及，压力空前，这时候就要考验你能不能及时调整策略了。

所以保持冷静是最重要的。

2.敢于放弃理由如上，做到后来题干长的一律不看（可能因为英文不好）3.善于估算记得以前是可以用计算器的，这次没让用。

算数很浪费时间，能猜就猜。

都考这么多年试了，这点经验要都没有的话也来不了吉大。

下面具体说一下各部分技巧第一部分，矩阵变换。

1. 单词（我英文比较烂，达人们可以跳过这一小节。

）有一些细节的东西需要事先准备一下，比如单词。

举例来说，Character这个词是的意思是字符，既包含字母也代表数字，考试的时候核计了许久也没想明白。

再比如diagonal，反正我在准备之前没见过这个词，考试的时候出现无数遍。

1:E D C B AC ADE BA DBC EB E D A CD C AE BStart at the fourth letter of Column 5 and follow the letters around the outside of the pattern in a clockwise direction. What is the second letter between the second E and the second B you come to?2:A B 2 C 31 1 B 3 DA 1BC 45 A 5 2 BE 5 D 2 CIn the row that has more letters than numbers, in which the numbers are separated by only one letter, and in which the numbers sum to less than the sum of the numbers in the second column, which letter comes just before the second number, counting from right to left?3:E D C B AC ADE BA DBC EB E D A CD C AE BIf Row 4 were reversed, what letter would be above E in Row 5?Section 1: Lots of grids consisting of various sym bols. Given questions like “what is the symbol directly left of ￡symbol in the third column when it has been reversed?”Section 2: Give the next number in the sequence, 40 sets of sequences and 8 minutes available.Section 3: Basic mental arithmetic, calculator supplied e.g. if x had 30% and y had 10% of the remaining how much was left over?Aptitude test, 1? hour long, 3 parts, first part matrix manipulation e.g. if you interchange row 1 and row 2 what would be the symbol in the 3 column of row 1. Second part you are given a sequences and you have to pick the next number in the sequence. Third part, general math problems e.g. percentages, fractions, multiplications.2. 看完题再动笔有些题干比较长，废话一堆，等你按照说明一步一步做到最后的时候才发现基本都是无用功。
