描述 | SQL查询及注释 | |
注释符 |
Access中没有专门的注释符号.因此"/*", "--"和"#"都没法使用.但是可以使用空字符"NULL"(%00)代替:
|
|
语法错误信息 | "[Microsoft][Driver ODBC Microsoft Access]" | |
多句执行 | 不支持. | |
联合查询 | Access支持联合查询,UNION后的FROM关键字必须使用一个已经存在的表名. | |
附属查询 |
Access支持附属查询(例如:"TOP 1"用来返回第一行的内容) :
|
|
LIMIT支持 |
LIMIT不被支持,但是在查询中可以声明"TOP N"来限制返回内容的行数:
|
|
让查询返回0行 |
在脚本在返回的HTML结果中只显示第一个查询的结果的时候非常有用:
|
|
字符串连接 |
不支持CONCAT()函数. 可以使用"&"或"+"操作来俩接两个字符串.在使用的时侯必须对这两个操作符进行URLencode编码:
|
|
子字符串 |
MID()函数:
|
|
字符串长度 |
LEN()函数:
|
|
暴WEB路径 |
可以通过对一个不存在的库进行SELECT操作.Access将会回应一条包含有完整路径的错误信息.:
|
|
取字符的ASCII值 |
ASC()函数:
|
|
ASCII值转换为字符 |
CHR()函数:
|
|
IF语句 |
可以使用IIF()函数. 语法 : IIF(condition, true, false) :
|
|
时间接口 | 不存在类似BENCHMARK()或SLEEP()的函数,但是可以使用大量(高负载)的查询来达到这个效果.点击这里查看参考. | |
验证文件是否存在 |
在注入的时候使用:
|
|
表名猜解 |
这里有一个简单的猜解access表名的java代码.我写他是为了更好的解释猜解表名的原理:

MySQL and SQL are essential skills for developers. 1.MySQL is an open source relational database management system, and SQL is the standard language used to manage and operate databases. 2.MySQL supports multiple storage engines through efficient data storage and retrieval functions, and SQL completes complex data operations through simple statements. 3. Examples of usage include basic queries and advanced queries, such as filtering and sorting by condition. 4. Common errors include syntax errors and performance issues, which can be optimized by checking SQL statements and using EXPLAIN commands. 5. Performance optimization techniques include using indexes, avoiding full table scanning, optimizing JOIN operations and improving code readability.

This article will explain how to improve website performance by analyzing Apache logs under the Debian system. 1. Log Analysis Basics Apache log records the detailed information of all HTTP requests, including IP address, timestamp, request URL, HTTP method and response code. In Debian systems, these logs are usually located in the /var/log/apache2/access.log and /var/log/apache2/error.log directories. Understanding the log structure is the first step in effective analysis. 2. Log analysis tool You can use a variety of tools to analyze Apache logs: Command line tools: grep, awk, sed and other command line tools.

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.

Apache server is a powerful web server software that acts as a bridge between browsers and website servers. 1. It handles HTTP requests and returns web page content based on requests; 2. Modular design allows extended functions, such as support for SSL encryption and dynamic web pages; 3. Configuration files (such as virtual host configurations) need to be carefully set to avoid security vulnerabilities, and optimize performance parameters, such as thread count and timeout time, in order to build high-performance and secure web applications.

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.

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

How to solve the MySQL "Access denied for user" error: 1. Check the user's permission to connect to the database; 2. Reset the password; 3. Allow remote connections; 4. Refresh permissions; 5. Check the database server configuration (bind-address, skip-grant-tables); 6. Check the firewall rules; 7. Restart the MySQL service. Tip: Make changes after backing up the database.

This article describes how to customize Apache's log format on Debian systems. The following steps will guide you through the configuration process: Step 1: Access the Apache configuration file The main Apache configuration file of the Debian system is usually located in /etc/apache2/apache2.conf or /etc/apache2/httpd.conf. Open the configuration file with root permissions using the following command: sudonano/etc/apache2/apache2.conf or sudonano/etc/apache2/httpd.conf Step 2: Define custom log formats to find or
