asp 数据库连接,读取,写入,修改的简单例子

Posted 2023-04-28

谁有 这样的列子,给一个.我晕..

搞了几天都搞不懂这最简单的。.网上的 10天ASP教程就不行.日...

谁有这样简单的列子,可以用的,给一个.最好带注释..
最好分几个文件,一个insert.asp 一个read.asp 一个gai.asp

1、数据库链接 conn.asp
<%
dim conn
dim dbpath
set conn=server.createobject("adodb.connection")
DBPath = Server.MapPath("数据库所在文件夹/数据库名.mdb")
conn.Open "driver=Microsoft Access Driver (*.mdb);dbq=" & DBPath
%>
2、所有需要数据库链接的页面都要包含<!--#include file="conn.asp"-->
3、数据库读：
<%
set rs=Server.CreateObject("ADODB.Recordset")
sql="select * from table_dayi where dayi_isreply=1 order by id desc"
rs.open sql,conn,1,1%>
<%=rs("dayi_title")%>
4、数据库写：
<%
set rs=server.CreateObject("adodb.recordset")
sqlstr="select * from table_dayi"
rs.open sqlstr,conn,1,3
rs.addnew
rs("dayi_who")=session("name")
rs("dayi_title")=changechr(request.Form("title"))
rs("dayi_question")=changechr(request.Form("question"))
rs("dayi_chapter")=request.Form("chapter")
rs("dayi_date")=now()
rs("dayi_isreply")=0
rs("dayi_ip")=Request.serverVariables("REMOTE_ADDR")
rs.update
conn.close
%>
5、数据库修改：
<%
set rs1=Server.CreateObject("ADODB.Recordset")
sql="select * from user where datediff('s',onlinetime,now())>600"
rs1.open sql,conn,1,3
rs1("onlinetime")=0
rs1("userip")=""
rs1.update

Network administrator itself is the technical post, therefore thetechnology must first. As for any technology most important, that mustthink each unit the demand, the simple possibility so long asconnected and can the exchange visits be good. The complex networkpossibly was several people even more people's matter, had thedivision of labor and the cooperation, various person of maintenanceand the study direction is dissimilar. The common middle and smallscale unit all does not suppose the network management, because thecomputer are few, does not need specially to set up sentries, hasoutside the question to ask the person to go. Surpasses 20 unitspossibly to have to suppose the special network management or theconcurrent job network management, such unit's network management hasthe IT various aspects on the request the knowledge, jumps over GuangYuehao. Two: The enterprise network management needs to grasp the skill makesnetwork management nearly anything to need to know that a spot, notnecessarily must fine, certainly you also must have own strong point. 1. Made the system is the most basic request, from 98 to 2003, all hadto be able to play from unix to linux, fine (this difficulty systemvery was not necessarily all high) 2. Can maintain the PC hardware and the printer (to spurts inkfrom needle type to arrive laser), if this part does is not good,possibly every day suffices your busy morning 3. Meets the MAIL service and the customer end disposition and themanagement, mainly has Exchange, Imail, Qmail, Sendmail and so on, thepresent enterprise all has own MAIL, moreover occupies the status highis absolutely not allow to neglect 4. To the windows/*nix system must know the common servicedisposition, most basic certainly is DHCP (DHCPD), DNS (BIND), IIS(APACHE), FTP (WUFTPD/VSFTPD), AD (SAMBA), WINS and so on, if theseall not too understand, hurries ruthlessly to make up Otherwise didnot must go 5. The database at least needs to understand SQL SERVER with mysql, ifmeets ORACLE/SYBASE/DB2/INFORMIX, that wages definitely can be high10% (ha-ha a little exaggerates, if these can, but also did not makeDBA to go?) 6. Certainly wants to the switchboard and the router simpleestablishment and the management, otherwise only could go to the smallbusiness (mainly is CISCO, China is 3COM, north electricity, certainlyto TP-LINK, the D-LINK low end equipment also had to be familiarwith). 7. The familiar synthesis wiring technology (at least knew howmakes 568A/568B), the optical fiber technology also needs slightly tounderstand 12, if you respond to a call for recruits is the factoryspeech, the workshop often can pull the optical fiber with theworkshop between 8. Must know how plans the network, enhances the network the stability(to be most important) as far as possible, security and use factorand so on 9. Can write the script, was not effective is windows or *nix, thescript often can twice the result with half the effort cause yourworking efficiency (to assemble language and so on /C has beenbetter). 10. Must know how the fast security backup with does restorethe data 11. To technology and so on proxy firewall 杀毒 must be familiar,otherwise which day was your network completely paralysed has notknown our matter The 12.WLAN technology also must grasp as soon as possible, this is atendency, the very many enterprises' partial networks all melted intoit 13. To turns on the net technology to have to be familiar, at leastmust know ADSL, ISDN, FTTX, FR, how DDN is a matter 14. Certainly some companies hire when the manager requests you tomeet ASP, PHOTOSHOP, DW and so on, they mainly are the website routinemaintenance 15. Must have a clear understanding to the entire network model andthe overhead construction, at least must know the level, theagreement, the connection, the service and so on knows, if can gnawthoroughly the TCP/IP agreement these three volumes book, then youwere allowed to start the cow 16. Has a clear understanding to the ERP system 17. Most important, also is decided the destiny the matter, needs tolearn " Endures " Small does not endure then the chaotic bigstratagem, this speech is very appropriate to the network management 参考技术B tttttttttttttttttt

java能否读取csv文件的同时也写入数据？

java能否读取csv文件的同时也写入数据？能不能给个例子我看看。谢谢各位高手了。

首先，答案是肯定的。如果是指写入数据库，则

看复杂度，如果简单的，按TEXT读、拆分一下就可以。

如果复杂，可以当EXCEL，使用POI读进去。

读取足够的信息，就使用JDBC、等，写入数据库

如果是写csv文件本身，那使用RandomAccess，读写指定的位置追问

我就想写入csv文件，数据库以后再说，能给个读取的同时写入的例子吗？

参考技术A 百度一下csvreader,csvwriter ，已经有人写过两个工具类。追问

我知道，这两个单独用的时候可以，我想一边读取数据一边写入怎么弄？给个例子呗
