Question

我正在尝试插入到mysql表中。这是我的代码......

        Dim cmdText = "INSERT INTO complete_log ('cust_id', 'business', 'note', 'date_stamp') values (@cid,@bus,@notey,@datey)"
    Dim conn As New MySqlConnection("server=theipofserver;user id=id;password=mypass;database=thedatabase")
    Using cmd = New MySqlCommand(cmdText, conn)
        conn.Open()
        Dim testy As String
        testy = TextBox1.Text
        Dim dater = Date.Today + TimeOfDay
        cmd.Parameters.AddWithValue("@cid", c_id)
        cmd.Parameters.AddWithValue("@bus", c_business)
        cmd.Parameters.AddWithValue("@notey", testy)
        cmd.Parameters.AddWithValue("@datey", dater)
        cmd.ExecuteNonQuery()
    End Using

但是，我收到以下错误：

MySql.Data.MySqlClient.MySqlException: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ''cust_id', 'business', 'note', 'date_stamp') values ('ID','null','first one'' at line 1

我要插入的表有4列，所有varchars都有足够的空间（varchar（100））

以下是有关错误的详细信息...第31行发生错误...

Line 29:             cmd.Parameters.AddWithValue("@notey", testy)
Line 30:             cmd.Parameters.AddWithValue("@datey", dater)
Line 31:             cmd.ExecuteNonQuery()
Line 32:         End Using
Line 33:         TextBox1.Font.Bold = True

那么，我在这里做错了什么？关于更好地插入mysql表的方法的任何提示将不胜感激！

Answer 1

不要在表名或列名周围使用引号。

INSERT INTO complete_log (`cust_id`, `business`, `note`, `date_stamp`)
values (@cid,@bus,@notey,@datey)

如果要转义表名和列名，请使用反引号。但你只需要逃避reserved words in MySQL。

Answer 2

不要在叛逆者中指定列名

而不是

Dim cmdText = "INSERT INTO complete_log ('cust_id', 'business', 'note', 'date_stamp') values (@cid,@bus,@notey,@datey)"

待办事项

Dim cmdText = "INSERT INTO complete_log (cust_id, business, note, date_stamp) values (@cid,@bus,@notey,@datey)"

Answer 3

更改

INSERT INTO complete_log ('cust_id', 'business', 'note', 'date_stamp')

到

INSERT INTO complete_log (cust_id, business, note, date_stamp)
