Question

尝试从数据库中删除数据时收到此错误。

附加信息：查询表达式中的语法错误（缺少运算符）＆＃39; [项目ID] 1＆＃39;。

有人可以帮忙吗？感谢。

Private Sub btnDelete_Click(sender As Object, e As EventArgs) Handles btnDelete.Click
    'Check for the selected item in the list
    If Me.dgvData.Rows.Count > 0 Then
        If Me.dgvData.SelectedRows.Count > 0 Then
            Dim intItemID As Integer = Me.dgvData.SelectedRows(0).Cells("Item ID").Value
            'Open the connection 
            If Not cnn.State = ConnectionState.Open Then
                cnn.Open()
            End If

            'Delete data 
            Dim cmd As New OleDb.OleDbCommand
            cmd.Connection = cnn
            cmd.CommandText = "DELETE FROM Product WHERE [Item ID]" & intItemID
            cmd.ExecuteNonQuery()
            'Refresh the data 
            Me.RefreshData()

            'Close the connection
            cnn.Close()
        End If
    End If
End Sub

结束班

Answer 1

change cmd.CommandText = "DELETE FROM Product WHERE [Item ID]" & intItemID

到

cmd.CommandText = "DELETE FROM Product WHERE [Item ID] = " & intItemID

你忘记了等号

附加信息：查询表达式'[Item ID] 1'中的语法错误（缺少运算符）
