前题是必须安装好activeperl (505以上),以及MS Access 97

一. 安装Win32-ODBC模块

步骤1:

从TOOLS栏目中下载Win32-ODBC.zip,下载完后用winzip解开到一个temp目录,共有三个文件:

Readme

Win32-ODBC.ppd

Win32-ODBC.tar.gz

步骤2:

在DOS窗口下,temp目录中运行下面的DOS命令:

ppm install Win32-ODBC.ppd

二. 准备测试用数据库(ACCESS)

步骤1:

启动MS ACCESS,建立一个新空数据库,命名为odbctest.mdb,保存在某一目录中(记住路径)。

步骤2:

然后新建一个表,建立三个字段:

字段名称 数据类型

Name 字符,长度50

Email 字符,长度50

Age 数字,长整型

将这个表保存为address(注意这个例子中,没有用自动增加的ID).输入若干记录:

Nighthawk nighthawk@163.net 20 1234567

John jt@163.net 24 0284393293

kit kit@21cn.com 18 3948932

保存后,关闭数据库文件。

步骤3:

打开控制面板中的 ODBC数据源(32位),在用户DSN栏中,找到用户数据源列表,选中名称为“MS Access 97 Database”的一行,然后按“配置”键。

在Database框中按"Select..",选择步骤1.2中建立的数据库文件odbctest.mdb,按OK即可。ODBC设置中的其它项目全部采用缺省设置,然后就是OK,确定,关闭对话窗口。

三. 这时候,数据库已经可以用了,我们来测试一下:

#!/usr/bin/perl

use Win32::ODBC;

$DSN = "MS Access 97 Database";

$DBase = "access.mdb";

#连接数据库

if (!($db = new Win32::ODBC($DSN))){

print "连接数据库失败.n";

exit();

}

else{

print "连接数据库成功 (连接号:", $db->Connection(), ")nn";

}

#数据库中的表

print "数据库中的表:";

@tables = $db->TableList;

print @tables;

print "n";

#选择数据表

if (! $db->Sql("SELECT * FROM [address] WHERE age>=20") ){

@FieldNames = $db->FieldNames();

$Cols = $#FieldNames + 1;

#表中字段数

print "表address字段数:$Colsn";

#字段列表

for ($i = 0; $i
print "$FieldNames[$i]t";

}

print "n";

#列出年龄大于20的记录

while($db->FetchRow()) {

@values = $db->Data();

print @values;

print "n";

}

}

##### sql #########

#添加记录

$sqlinsert = "INSERT INTO address VALUES ('Euler', 'euler@21cn.com', 28, '021-345689')";

#更新记录

$sqlupdate = "UPDATE address SET age = age+10 ";

#删除记录

$sqldelete = "DELETE FROM address WHERE name='jimtyan'";

$rc = $db->Sql($sqlinsert);

die qq(SQL 失败 "$sqlinsert": ), $db->Error(), qq(n) if $rc;

$rc = $db->Sql($sqlupdate);

die qq(SQL 失败 "$sqlupdate": ), $db->Error(), qq(n) if $rc;

$rc = $db->Sql($sqldelete);

die qq(SQL 失败 "$sqldelete": ), $db->Error(), qq(n) if $rc;

#关闭链接

$db->Close();

MySQL's Role: Databases in Web ApplicationsMySQL's Role: Databases in Web ApplicationsApr 17, 2025 am 12:23 AM

The main role of MySQL in web applications is to store and manage data. 1.MySQL efficiently processes user information, product catalogs, transaction records and other data. 2. Through SQL query, developers can extract information from the database to generate dynamic content. 3.MySQL works based on the client-server model to ensure acceptable query speed.

MySQL: Building Your First DatabaseMySQL: Building Your First DatabaseApr 17, 2025 am 12:22 AM

The steps to build a MySQL database include: 1. Create a database and table, 2. Insert data, and 3. Conduct queries. First, use the CREATEDATABASE and CREATETABLE statements to create the database and table, then use the INSERTINTO statement to insert the data, and finally use the SELECT statement to query the data.

MySQL: A Beginner-Friendly Approach to Data StorageMySQL: A Beginner-Friendly Approach to Data StorageApr 17, 2025 am 12:21 AM

MySQL is suitable for beginners because it is easy to use and powerful. 1.MySQL is a relational database, and uses SQL for CRUD operations. 2. It is simple to install and requires the root user password to be configured. 3. Use INSERT, UPDATE, DELETE, and SELECT to perform data operations. 4. ORDERBY, WHERE and JOIN can be used for complex queries. 5. Debugging requires checking the syntax and use EXPLAIN to analyze the query. 6. Optimization suggestions include using indexes, choosing the right data type and good programming habits.

MySQL is suitable for beginners because: 1) easy to install and configure, 2) rich learning resources, 3) intuitive SQL syntax, 4) powerful tool support. Nevertheless, beginners need to overcome challenges such as database design, query optimization, security management, and data backup.

Explain the ACID properties (Atomicity, Consistency, Isolation, Durability).Explain the ACID properties (Atomicity, Consistency, Isolation, Durability).Apr 16, 2025 am 12:20 AM

ACID attributes include atomicity, consistency, isolation and durability, and are the cornerstone of database design. 1. Atomicity ensures that the transaction is either completely successful or completely failed. 2. Consistency ensures that the database remains consistent before and after a transaction. 3. Isolation ensures that transactions do not interfere with each other. 4. Persistence ensures that data is permanently saved after transaction submission.

MySQL: Database Management System vs. Programming LanguageMySQL: Database Management System vs. Programming LanguageApr 16, 2025 am 12:19 AM

MySQL is not only a database management system (DBMS) but also closely related to programming languages. 1) As a DBMS, MySQL is used to store, organize and retrieve data, and optimizing indexes can improve query performance. 2) Combining SQL with programming languages, embedded in Python, using ORM tools such as SQLAlchemy can simplify operations. 3) Performance optimization includes indexing, querying, caching, library and table division and transaction management.

MySQL: Managing Data with SQL CommandsMySQL: Managing Data with SQL CommandsApr 16, 2025 am 12:19 AM

MySQL uses SQL commands to manage data. 1. Basic commands include SELECT, INSERT, UPDATE and DELETE. 2. Advanced usage involves JOIN, subquery and aggregate functions. 3. Common errors include syntax, logic and performance issues. 4. Optimization tips include using indexes, avoiding SELECT* and using LIMIT.
