主题：sel ect组合条件统计Count报错 语法错误？

第一次查询，进入下一页，分别看看弹出的数据

Dim e As RequestEventArgs = args(0)

Dim page As Integer = 0 '默认page为0,显示第一页

Dim pageRows As Integer = 10 '每页15行

If e.GetValues.ContainsKey("page") Then  '如果地址中有page参数

    Integer.TryParse(e.GetValues("page"), page) '提取page参数

End If

msgbox(page)

Dim StartRow As Integer = page * pageRows + 1 '此页第一行

msgbox(StartRow)

Dim EndRow As Integer = (page + 1) * pageRows '此页最后一行

msgbox(EndRow)

'获取该页数据

……

Dim cmd As New SQLCommand

cmd.ConnectionName = "智慧党建" '记得设置数据源名称

cmd.CommandText = "Select Count(*) From {党员信息} where " & flt

msgbox(cmd.CommAndText) 

Dim Count As Integer = cmd.ExecuteScalar() '获取总的行数

'Dim Pages As Integer = Math.Ceiling(Count/PageRows) '计算出总页数

MessageBox.Show(count)

If flt > "" Then

    cmd.CommandText = "Select * From (Select Row_Number() Over(Order by _Identify) As [NO.],[_Identify],姓名,支部名称 as 所属支部,联系电话  From 党员信息 where " & flt & ") As a "

Else

    cmd.CommandText = "Select * From (Select Row_Number() Over(Order by _Identify) As [NO.],[_Identify],姓名,支部名称 as 所属支部,联系电话  From 党员信息) As a "

End If

cmd.CommandText = cmd.CommandText & "  Where [NO.]>= " & StartRow & " And [NO.] <= " & EndRow

msgbox(cmd.CommAndText) 

Dim dt As DataTable = cmd.ExecuteReader

http://www.foxtable.com/mobilehelp/index.htm?page=0128.htm 参照这个帮助说明  代码修正如下  

结果问题还是和上面描述一样  点下一页的时候flt的值为空  就会提示where附近语法错误

老师我想进一步实现  可以选择多个姓名  怎么实现呢？
