Question

当我尝试注册用户时，任何人都可以帮助我收到错误，本地一切正常但我在远程上传文件时收到错误。继承我的代码

    Dim conn As OleDbConnection
    Dim strinsert As String
    Dim cmdinsert As OleDbCommand

    conn = New OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=|DataDirectory|sabersolutions.mdb")
    strinsert = "INSERT INTO register(Name,Email,Passwords,Newsletter,ReportTemplates,ReturningMember,Sponsor)SELECT TOP 1 @Name,@Email,@Passwords,@Newsletter,@ReportTemplates,@ReturningMember,@Sponsor FROM register WHERE NOT EXISTS(SELECT 1 FROM register WHERE Name=@Name AND Email=@Email AND Passwords=@Passwords AND Newsletter=@Newsletter AND ReportTemplates=@ReportTemplates AND ReturningMember=@ReturningMember AND Sponsor=@Sponsor)"

    cmdinsert = New OleDbCommand(strinsert, conn)
    cmdinsert.Parameters.Add("@Name", OleDbType.VarWChar, 255).Value = txtName.Text
    cmdinsert.Parameters.Add("@Email", OleDbType.VarWChar, 255).Value = txtEmail.Text
    cmdinsert.Parameters.Add("@Passwords", OleDbType.VarWChar, 255).Value = txtPass.Text
    cmdinsert.Parameters.Add("@Sponsor", OleDbType.Boolean, 1).Value = ckSponsor.Checked
    cmdinsert.Parameters.Add("@Newsletter", OleDbType.Boolean, 1).Value = ckNews.Checked
    cmdinsert.Parameters.Add("@ReportTemplates", OleDbType.Boolean, 1).Value = ckReportTemp.Checked
    cmdinsert.Parameters.Add("@ReturningMember", OleDbType.Boolean, 1).Value = ckRSponsor.Checked
    cmdinsert.Parameters.Add("@Sponsor", OleDbType.Boolean, 1).Value = ckSponsor.Checked

    cmdinsert.Connection.Open()

    cmdinsert.ExecuteNonQuery()

    cmdinsert.Connection.Close()

    LblSuccess.Text = "You have successfully Register, Please Login to view our Online Booking Sytem."

我收到错误

我远不是Access的新手，但你的查询中有错误;

....
SELECT TOP 1 @Name,@Email,@Passwords,@Newsletter,
             @ReportTemplates,@ReturningMember,@Sponsor 
FROM register 
...

应该是;

....
SELECT TOP 1 Name,Email,Passwords,Newsletter,
             ReportTemplates,ReturningMember,Sponsor 
FROM register 
...

您的“可更新查询”问题很可能是您尝试在Access上使用SQL Server UPDATE查询，但Access UPDATE语法远非标准，可能需要重写您的子查询作为连接。拥有更多Access-Foo的人可能会帮助你。

或者，您可以尝试访问查询向导，它可以帮助您使用正确的Access语法重写查询。
