Question

我正在学习MySQL，我正在尝试创建一个数据库和一些表。我在其中两张桌子上收到错误，但在我的生活中，我看不到我错过的内容。

抛出错误的两个表是： MAINTANANCE_REPAIR 和 TRIP。

如果有人能够发现我所缺少的东西，那将会非常有帮助。谢谢！

在两个表上，您在表定义的最后一行有一个额外的逗号：

Sub OpenSQL(ByRef conSQL)

Set conSQL = Server.CreateObject("ADODB.Connection")
    conSQL.connectionTimeout = 60
    ConSQL.CommandTimeout = 0
    conSQL.Open "my driver / database"

End Sub

删除它，你会很高兴。
