一、基本操作题
在考生文件夹下,“samp1.mdb”数据库文件中已建立三个关联表对象(名为“职工表”、“物品表”和“销售业绩表”)。试按以下要求,完成表和窗体的各种操作:
(1)向表对象“物品表”中增添一个字段,名称为“生产日期”、类型为“日期/时间型”。设置该字段默认值为2006年4月1日;
(2)分析表对象“销售业绩表”的字段构成、判断并设置其主键;
(3)将考生文件夹下Excel文件Test.xls中的数据导入到当前数据库中。要求:数据中的第一行作为字段名,选“学号”数据列为主键,导入表对象命名为“tTest”;
(4)建立表对象“职工表”、“物品表”和“销售业绩表”的表间关系,并实施参照完整性;
(5)将窗体fTest中名为“bTitle”的控件设置为“特殊效果:凿痕”显示;
(6)在窗体fTest中,以命令按钮“bt1”为基准(这里按钮“bt1”和“bt3”尺寸相同、左边对齐),调整命令按钮“bt2”的大小与位置。要求:按钮“bt2”的大小尺寸与按钮“bt1”相同、左边界与按钮“bt1”左对齐、竖直方向位于按钮“bt1”和“bt3”的中间位置。
二、简单应用题
考生文件夹下存在一个数据库文件“samp2.mdb”,里面已经设计好表对象“tTeacher”、“tCourse”、“tStud”和“tGrade”,试按以下要求完成设计:
(1)创建一个查询,查找并显示“教师姓名”、“职称”、“学院”、“课程ID”、“课程名称”和“上课日期”六个字段的内容,所建查询名为“qT1”;
(2)创建一个查询,按输入的教师姓名查找教师的授课情况,并按“上课日期”字段降序显示“教师姓名”、“课程名称”、“上课日期”三个字段的内容,所建查询名为“qT2”;当运行该查询时,应显示参数提示信息:“请输入教师姓名”;
(3)创建一个查询,查找学生的课程成绩大于等于80且小于等于100的学生情况,显示“学生姓名”、“课程名称”和“成绩”三个字段的内容,所建查询名为“qT3”。
(4)对表“tGrade”创建一个分组总计查询,假设学号字段的前4位代表年级,要统计各个年级不同课程的平均成绩,显示“年级”、“课程ID”和“成绩之Avg”,并按“年级”降序排列,所建查询为“qT4”。
三、综合应用题
考生文件夹下存在一个数据库文件“samp3.mdb”,里面已经设计了表对象“tEmp”、查询对象“qEmp”和窗体对象“fEmp”。同时,给出窗体对象“fEmp”上“退出”按钮的单击事件代码,试按以下功能要求补充设计。
(1)将窗体“fEmp”上文本框“tSS”更改为组合框类型,并保持控件名称不变;
(2)修改查询对象“qEmp”为参数查询,参数为引用窗体对象“fEmp”上文本框“tSS”的输入值;
(3)设置窗体对象“fEmp”上文本框“tAge”为计算控件。要求根据“年龄”字段值依据以下计算公式计算并显示人员的出生年;
计算公式: 出生年=Year(Date())-年龄 或 出生年=Year(Now())-年龄
(4)单击“退出”按钮(名为“bt2”),关闭窗体。补充事件代码。
注意:不允许修改数据库中的表对象“tEmp”;不允许修改查询对象“qEmp”中未涉及的内容;不允许修改窗体对象“fEmp”中未涉及的控件和属性;已给事件过程,只允许在“*****Add*****”与“*****Add*****”之间的空行内补充语句、完成设计,不允许增删和修改其它位置已存在的语句。

SQL IF statements are used to conditionally execute SQL statements, with the syntax as: IF (condition) THEN {statement} ELSE {statement} END IF;. The condition can be any valid SQL expression, and if the condition is true, execute the THEN clause; if the condition is false, execute the ELSE clause. IF statements can be nested, allowing for more complex conditional checks.

How to configure Zend in Apache? The steps to configure Zend Framework in an Apache Web Server are as follows: Install Zend Framework and extract it into the Web Server directory. Create a .htaccess file. Create the Zend application directory and add the index.php file. Configure the Zend application (application.ini). Restart the Apache Web server.

The advantage of multithreading is that it can improve performance and resource utilization, especially for processing large amounts of data or performing time-consuming operations. It allows multiple tasks to be performed simultaneously, improving efficiency. However, too many threads can lead to performance degradation, so you need to carefully select the number of threads based on the number of CPU cores and task characteristics. In addition, multi-threaded programming involves challenges such as deadlock and race conditions, which need to be solved using synchronization mechanisms, and requires solid knowledge of concurrent programming, weighing the pros and cons and using them with caution.

The main reasons why you cannot log in to MySQL as root are permission problems, configuration file errors, password inconsistent, socket file problems, or firewall interception. The solution includes: check whether the bind-address parameter in the configuration file is configured correctly. Check whether the root user permissions have been modified or deleted and reset. Verify that the password is accurate, including case and special characters. Check socket file permission settings and paths. Check that the firewall blocks connections to the MySQL server.

This article describes how to effectively monitor the SSL performance of Nginx servers on Debian systems. We will use NginxExporter to export Nginx status data to Prometheus and then visually display it through Grafana. Step 1: Configuring Nginx First, we need to enable the stub_status module in the Nginx configuration file to obtain the status information of Nginx. Add the following snippet in your Nginx configuration file (usually located in /etc/nginx/nginx.conf or its include file): location/nginx_status{stub_status

The key to PHPMyAdmin security defense strategy is: 1. Use the latest version of PHPMyAdmin and regularly update PHP and MySQL; 2. Strictly control access rights, use .htaccess or web server access control; 3. Enable strong password and two-factor authentication; 4. Back up the database regularly; 5. Carefully check the configuration files to avoid exposing sensitive information; 6. Use Web Application Firewall (WAF); 7. Carry out security audits. These measures can effectively reduce the security risks caused by PHPMyAdmin due to improper configuration, over-old version or environmental security risks, and ensure the security of the database.

Effective monitoring and defense against malicious website access is crucial to the Apache server on the Debian system. Apache access logs are the key source of information to identify such threats. This article will guide you on how to analyze logs and take defensive measures. The Apache access log that identifies malicious access behaviors Debian systems is usually located in /var/log/apache2/access.log. You can analyze the logs in a variety of ways: Log file location confirmation: First, please confirm the exact location of your Apache access log, which may vary slightly depending on the system configuration. Command line tool analysis: Use grep command to search for specific patterns, such as grep "404"
