Question

尝试插入访问数据库时，我在INSERT INTO语句中遇到语法错误。发生错误的代码段是

 If (checkBox.IsChecked) Then
        cmd.CommandText = "INSERT INTO Participants([Full Name],[From],[Gender],[Category],[Event],[Weight],[DOB],[Age]) VALUES(" + textBox.Text + "," + textBox_Copy2.Text + "," + gender + "," + comboBox.SelectedItem.ToString + "," + "Kata" + "," + textBox_Copy.Text + "," + dp.Text + "," + textBox_Copy1.Text
        cmd.ExecuteNonQuery()
    End If
    If (checkBox_Copy2.IsChecked) Then
        cmd.CommandText = "INSERT INTO Participants([Full Name],[From],[Gender],[Category],[Event],[Weight],[DOB],[Age]) VALUES(" + textBox.Text + "," + textBox_Copy2.Text + "," + gender + "," + comboBox.SelectedItem.ToString + "," + "Kumite" + "," + textBox_Copy.Text + "," + dp.Text + "," + textBox_Copy1.Text
        cmd.ExecuteNonQuery()
    End If
    If (checkBox_Copy1.IsChecked) Then
        cmd.CommandText = "INSERT INTO Participants([Full Name],[From],[Gender],[Category],[Event],[Weight],[DOB],[Age]) VALUES(" + textBox.Text + "," + textBox_Copy2.Text + "," + gender + "," + comboBox.SelectedItem.ToString + "," + "Team Kata" + "," + textBox_Copy.Text + "," + dp.Text + "," + textBox_Copy1.Text
        cmd.ExecuteNonQuery()
    End If
    If (checkBox_Copy.IsChecked) Then
        cmd.CommandText = "INSERT INTO Participants([Full Name],[From],[Gender],[Category],[Event],[Weight],[DOB],[Age]) VALUES(" + textBox.Text + "," + textBox_Copy2.Text + "," + gender + "," + comboBox.SelectedItem.ToString + "," + "Team Kumite" + "," + textBox_Copy.Text + "," + dp.Text + "," + textBox_Copy1.Text
        cmd.ExecuteNonQuery()
    End If

对于文本字段，您必须将VALUES子句中的值括在引号中。请注意此示例中的单引号

"INSERT INTO Participants([Full Name]) VALUES ('" + textBox.Text + "')"

但是，使用参数而不是将值正确放在SQL语句中会更好。看到这个 https://msdn.microsoft.com/en-us/library/tyy0sz6b(v=vs.110).aspx
