标题: 如何累加？？？？？ [打印本页] 作者: 释放压力 时间: 2010-1-10 06:06 标题: 如何累加？？？？？ 有10个同学，其中有三个同学是同一天生日，现在要写一段语句通过select 语句和循环语句将三名同学的姓名读出来且赋值给name,即name= a(0)+a(1)+a(2)，再以response.write name 输出，不知用数组如何写？？拜托各位了作者: 尐妖 时间: 2010-1-10 06:06
楼主的代码怎么写的？作者: v九天〓云龙 时间: 2010-1-10 06:07
sql="select * from member where DateDiff('d',birthday,'"&Year(now())&"-"&Month(now())&"-"&Day(Now())&")=0 And DateDiff('m',birthday,'"&Year(now()&"-"&Month(now())&"-"&Day(now)&")=0 "
多了一个*号作者: 封xin封mg 时间: 2010-1-10 06:07
语句如下:(数据库连接文件已经在上面了)
<%
set rs=server.createobject("adodb.recordset")
sql="select * from member where DateDiff('d',birthday,'"&Year(now())&"-"&Month(now())&"-"&Day(Now())&")=0 And DateDiff('m',birthday,'"&Year(now*()&"-"&Month(now())&"-"&Day(now)&")=0 "
rs.Open sql,conn,1,1
Do while not rs.EOF
Response.Write "今天生日的用户"&rs("membername")
rs.MoveNext
Loop
%>
错误提示:
错误类型：
Microsoft VBScript 编译器错误 (0x800A03EA)
语法错误
/0315/admin/case_tj/dealcount.asp, line 960, column 145
sql="select * from member where DateDiff('d',birthday,'"&Year(now())&"-"&Month(now())&"-"&Day(Now())&")=0 And DateDiff('m',birthday,'"&Year(now*()&"-"&Month(now())&"-"&Day(now)&")=0 "
上面错误提示说明以下这句话是错的.
sql="select * from member where DateDiff('d',birthday,'"&Year(now())&"-"&Month(now())&"-"&Day(Now())&")=0 And DateDiff('m',birthday,'"&Year(now*()&"-"&Month(now())&"-"&Day(now)&")=0 "作者: 龙行天下 时间: 2010-1-10 06:07
谢谢，谢谢，我在一次感到了大家积极帮助的火热的心，只用一句话总结，世上还是好人多呀，再次表示感谢，等我测试完一定再回复。作者: 小点点14504 时间: 2010-1-10 06:07
Set rs=con.Execute("select name from [user] where DateDiff('d',birthday,'"&Year(now())&"-"&Month(now())&"-"&Day(Now())&")=0 And DateDiff('m',birthday,'"&Year(now*()&"-"&Month(now())&"-"&Day(now)&")=0 ")
Do while not rs.EOF
Response.Write "今天生日的用户"&rs("name")
rs.MoveNext
Loop作者: 星溯~~~~天空 时间: 2010-1-10 06:07
？为什么要累加？
用select循环直接用rs输出呢？
比如
Access数据库
Set rs=con.Execute("select name from [user] where DateDiff('d',birthday,'"&Year()&"-"&Month()&"-"&Day(Now)&")=0")
Do Until rs.EOF
Response.Write "今天生日的用户"&rs("name")
rs.MoveNext

再次表示感谢，我才学习不久，所以很多都不熟悉，希望以后多多指教。
但是按照这条语句进行查询，总是出现错误，说连接数据库时间超长，不知何故，望能解答。作者: 别问我是谁 时间: 2010-1-10 06:07
Set rs=con.Execute("select name from [user] where DateDiff('d',birthday,'"&Year()&"-"&Month()&"-"&Day(Now)&")=0 And DateDiff('m',birthday,'"&Year()&"-"&Month()&"-"&Day(Now)&")=0 ")
加And连接即可作者: ^o^星禾じ☆v 时间: 2010-1-10 06:07
感谢帮忙，我还有点没弄明白
DateDiff('d',birthday,'"&Year()&"-"&Month()&"-"&Day(Now)&"')=0"
这句好像有点问题，生日相同的只有月和日，所以必须取出birthday中的月、日与今天系统的月、日相减为0才对吧，不知说的是否对，再次谢谢回帖
