【问题描述】：

我正在将记录插入数据库，但参数“日期”出现错误。任何想法都会很好。

myConnection.Open()
Dim sqlQry As String = "INSERT INTO MasterLabNumber (LabNumber, Location, Date)" + "VALUES(@LabNumber, @Location, @Date)"
Dim str As String
str = "SELECT * FROM MasterLabNumber WHERE (LabNumber = " & TextBox1.Text & ")"
Dim d As System.DateTime = DateTime.Now.ToString("yyyy/MM/dd")
Dim cmd As OleDbCommand = New OleDbCommand(sqlQry, myConnection)
cmd.Parameters.AddWithValue("@LabNumber", TextBox1.Text)
cmd.Parameters.AddWithValue("@Location", ComboBox1.Text)
cmd.Parameters.AddWithValue("@Date", d)

cmd.ExecuteNonQuery() <-- gets error here relating to adding the parameter date.

【问题讨论】：

试试Dim d As String = DateTime.Now.ToString("yyyy/MM/dd")

您插入的不是日期而是字符串

【参考方案1】：

是的，这是因为Date 是您在插入语句中使用的保留字。您需要使用[]

将其转义，如下所示

INSERT INTO MasterLabNumber (LabNumber, Location, [Date])

你的插入语句应该变成

Dim sqlQry As String = "INSERT INTO MasterLabNumber (LabNumber, Location, [Date]) VALUES(@LabNumber, @Location, @Date)"
