1、我的ASP经验之路(4)--连接access数据库的两种方法、读取数据库内容这篇主要介绍以下两个问题:asp连接access数据库常用的两种方法、asp创建记录集与如何读取数据库的内容。ASP最常连接的是ACCESS与MSSQL两种数据库,本文先介绍简单的连接ACCESS数据库的两种常用方法。假设数据库名称为data.mdb,位于根目录下,与conn.asp文件同一目录。连接数据库文件conn.asp写法如下:第一种:<%dimconn  dimconnstrconnstr="DBQ="+server.

2、mappath("data.mdb")+";DefaultDir=;DRIVER={MicrosoftAccessDriver(*.mdb)};"setconn=server.createobject("ADODB.CONNECTION") '创建数据库连接对象conn.openconnstr'连接数据库%>第二种:<%dimconn  dimconnstrConnstr="Provider=Microsoft.Jet.OLEDB.4.0;DataSource="&Server.MapPath("dat

3、a.mdb")Setconn=Server.CreateObject("ADODB.Connection")Conn.OpenConnstr%>接下来,我们看下asp是如何创建记录集以及如何来读取数据库里的内容的。首先,我们要建一个数据库,里面放些需要读取的内容。1、建立一个数据库文件,名称估且命为data.mdb,里面准备存放一些公司企业的电话地址等内容。数据库中建一个名为company的表,表设计以下四个字段:companyname,tel,address,website(公司名称,电话,地址,网址

4、),字段类型全部选择“文本”,字段大小设置为250,创建好表后,打开表,自己输入随意输入几条记录值(所有建立数据库的具体操作本文略过)建好后,表设计如下图:打开表,内容如下:2、新建一个文件名为index.aspindex.asp文件代码里,首先要建立数据库连接,代码如上面介绍:dimconn  dimconnstrconnstr="DBQ="+server.mappath("data.mdb")+";DefaultDir=;DRIVER={MicrosoftAccessDriver(*.mdb)};"

5、setconn=server.createobject("ADODB.CONNECTION") '创建数据库连接对象conn.openconnstr'连接数据库创建记录集:setrs=server.CreateObject("adodb.recordset")'创建rs记录集sql="select*from[company]"'读取数据库的SQL语句串rs.opensql,conn,1,1'打开记录集读取数据库代码:结合前面介绍过的dowhile...loop语句来循环读取多条记录内容

6、th="100%"border="0"cellspacing="0"cellpadding="0"> <%dowhilenotrs.eof 'rs.eof意思是最后一条记录,rs.bof的意思是第一条记录,所以这句话的意思是:当不是最后一条记录时,输出下面的代码%>    <%=rs("companyname")%>   <%=rs("tel")%>   <%=rs("address")%>   

7、<%=rs("website")%>"target="_blank"><%=rs("website")%>  <%rs.movenext'移到下一条记录loop%>所有代码放在一起就是index.asp的所有代码。如下:<%dimconn dimconnstrconnstr="DBQ="+server.mappath("data.mdb")+";DefaultDir=;DRIVER={MicrosoftAccessDriver(*.mdb)};"setconn

8、=server.createobject("ADODB.CONNECTION")'创建数据库连接对象conn.openconnstr'连接数据库setrs=server.CreateObject("adodb.recordset")'创建rs记录集sql="select*from[company]"'读取数据库的SQL语句串rs.opensql,conn,1,1'打开记录集%>连接数据库与读取数据库内容</p>
