请问；set rs=server.CreateObject("adodb.recordset")是什么意思?

请问；set rs=server.CreateObject(adodb.recordset)是什么意思? set rs=server.CreateObject(adodb.recordset) set rs=server.CreateObject(adodb.recordset) 我知道这是创建一个数据库实例,但是什么是数据库实例?还有rs这个东西也不是一个变量,他在程序里边rs.update 等操作是 xingming=trim(request(xingming))xingbie=trim(request(xingbie))chushengsj=trim(request(chushengsj))sql=select * from mainjg where id is nullset rs=server.CreateObject(adodb.recordset)rs.open sql,conn,1,2rs.addnewrs(login123)=login123rs(pw 解释下列语句的作用?LoginName=trim(request.form(LoginName)) Password=MD5(trim(request.form(Password))) set rs = server.createobject(adodb.recordset) SQL=select * from Nwebadmin where username='&LoginName&'and password='&Password&' 请问下RS.这个是WinCC关于SQL数据库的一小段,其中的RS.EOF是啥意思的?谢谢啦strSQL = "ｓｅｌｅｃｔ * From SQL_DATA "Set Rs = cn.Execute(StrSQL)If Rs.EOF Then .Else Do While Not Rs.EOF. set rsClass=server.CreateObject(adodb.recordset)是什么意思? set rsNewsUpdata = Server.CreateObject(ADODB.Recordset)的意思? IF Not Rs.Bof [asp]asp里的.IF Not Rs.Bof Set Rs = Conn.Execute(Select * From Nt_Imgbook)IF Not Rs.Bof ThentitleIDArr = 全部商品1ElsetitleIDArr = 全部商品2End IFresponse.write titleIDArr Set rs = cn.Execute(insert into data (tcp_data) values (' & a & ')) set conn = Server.CreateObject(ADODB.Connection)conn.Open Application(strConn)“strConn”是什么啊 看看这个代码里的 exit for for 1= 1 to rs.recordcount //rs为一个记录集.Rs.movenextif Rs.eof then exit fornext end if 请问当rs.eof为真时执行 exit for next 这几句计算机语言是什么意思Dim cnn As ADODB.ConnectionDim rs As ADODB.RecordsetDim connect_string As StringDim statestring As StringSet cnn = New ADODB.ConnectionSet rs = New ADODB.Recordsetconnect_string = Provider=sqloledb.1;Server=127 Set rs = conn.Execute(sql)是什么意思啊?VB,遇到这么一句Set rs = conn.Execute(sql)其中的conn.Execute(sql)表示什么啊?SQL是在别的程序段查询出来的. asp代码含义请高手解释一下这几句是什么意思tmpmess=Server.HtmlEncode(request.form(name))tmpmess=replace(tmpmess,chr(10), )set rstmp=server.createobject(adodb.recordset)set rstmp=conn.execute(Select * from feedbackinfo Where n set rst=Server.CreateObject(ADODB.recordset)这句话什么意思recordset这词啥意思CreateObject这词啥意思 informix server has not been set.Save anyway? 请问江淮和悦RS字母RS代表什么意思 什么是RS-232-C接口?
