一直没解决
in_time包含日期和时间,DTPicker1.value只有日期.现在我想取in_time的日期来和date1比较.可是比较不起.请问怎么改?
Dim rs_windows As New ADODB.Recordset
Dim sql As String
Dim date1 As String
date1 = Format(CDate(DTPicker1.Value), "yyyy-mm-dd ")
sql = "select * from information where mid(in_time,1,10)= ' " & date1 & " ' And flag = 0 "
rs_windows.CursorLocation = adUseClient
rs_windows.Open sql, conn, adOpenKeyset, adLockPessimistic


还有一个
Dim rs_save As New ADODB.Recordset
Dim sql As String
Dim var1 As String
Dim i As Long

If Trim(txtcar.Text) = " " Then
MsgBox "车牌号不能为空 ", vbOKOnly + vbExclamation, " "
txtcar.SetFocus
Exit Sub
End If
If Trim(txtphone.Text) = " " Then
MsgBox "车主手机号不能为空 ", vbOKOnly + vbExclamation, " "
txtphone.SetFocus
Exit Sub
End If
If Trim(cmbtype.Text) = " " Then
MsgBox "车辆类别不能为空 ", vbOKOnly + vbExclamation, " "
cmbtype.SetFocus
Exit Sub
End If
txttime.Text = Now()
var1 = cmbtype.Text

Select Case var1
Case "单桥车 "
i = 1
Case "双桥车 "
i = 2
Case "长车 "
i = 3
Case "吊车单桥 "
i = 4
Case "吊车双桥 "
i = 5
End Select


sql = "select * from Information "
rs_save.Open sql, conn, adOpenKeyset, adLockPessimistic

rs_save.MoveLast
conn.Execute "insert into Information values ( " & rs_save.Fields(0) + 1 & ", ' " & txtcar.Text & " ', ' " & txtphone.Text & " ', " & i & ", ' " & txttime.Text & " ', " & 0 & ", " & userID & ") "

MsgBox "录入成功 "
rs_save.Close
txtcar.Text = " "
txtphone.Text = " "
cmbtype.Text = " "
txttime.Text = " "

conn.Execute "insert into Information values ( " & rs_save.Fields(0) + 1 & ", ' " & txtcar.Text & " ', ' " & txtphone.Text & " ', " & i & ", ' " & txttime.Text & " ', " & 0 & ", " & userID & ") "

执行提示至少一个参数没有被设定指定值,是怎么回事呀??

[解决办法]
你debug.print你的SQL语句，就可以看到那儿不正确了，同时也可以放到查询分析器中去分析

根据vbman2003(家人)的修改建议,请你再次修改一下试试

conn.Execute "insert into Information (cl_number,cph,sj,cl_type_xh,in_time,flag,in_yg_id) values ( " & cstr(rs_save.Fields(0)) & ", ' " & txtcar.Text & " ', ' " & txtphone.Text & " ', " & cstr(Val(i)) & ", ' " & txttime.Text & " ',0, " & cstr(userID) & ") "
