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();

DeepSeek cannot convert files directly to PDF. Depending on the file type, you can use different methods: Common documents (Word, Excel, PowerPoint): Use Microsoft Office, LibreOffice and other software to export as PDF. Image: Save as PDF using image viewer or image processing software. Web pages: Use the browser's "Print into PDF" function or the dedicated web page to PDF tool. Uncommon formats: Find the right converter and convert it to PDF. It is crucial to choose the right tools and develop a plan based on the actual situation.

The Java reflection mechanism allows programs to dynamically modify the behavior of classes without modifying the source code. By operating the Class object, you can create instances through newInstance(), modify private field values, call private methods, etc. Reflection should be used with caution, however, as it can cause unexpected behavior and security issues, and has a performance overhead.

Ways to solve iframe cross-domain issues in Vue: CORS: Enable CORS support in the backend server and use XMLHttpRequest or fetch API to send CORS requests in Vue.

Proxy server: Set up a proxy server to forward requests, use a third-party library (such as axios) in Vue to send requests and set the proxy server URL.

Common exception types and their repair measures in Java function development During the development of Java functions, various exceptions may be encountered, which affect the correct execution of the function. The following are common exception types and their repair measures: 1. NullPointerException Description: Thrown when accessing an object that has not been initialized. Fix: Make sure you check the object for non-null before using it. Sample code: try{Stringname=null;System.out.println(name.length());}catch(NullPointerExceptione){

Apple's latest releases of iOS18, iPadOS18 and macOS Sequoia systems have added an important feature to the Photos application, designed to help users easily recover photos and videos lost or damaged due to various reasons. The new feature introduces an album called "Recovered" in the Tools section of the Photos app that will automatically appear when a user has pictures or videos on their device that are not part of their photo library. The emergence of the "Recovered" album provides a solution for photos and videos lost due to database corruption, the camera application not saving to the photo library correctly, or a third-party application managing the photo library. Users only need a few simple steps
