通过 VBA 更新 SQL 表会截断小数点

Question

我需要将一组值从 Excel 工作表更新到 SQL Server 表中。 这是 Excel 表：

我在 VBA 中编写了一些代码来执行此操作，但我不是很专业。 更新工作正常，除了截断小数的部分。

如您所见，小数点被截断。 SQL 上的字段声明为十进制 (19,5)。 VBA 代码肯定有问题。这是我的代码。

一种解决方法是用点替换十进制逗号。

Option Explicit

Sub connectDB()

    Const SQLUser = "#"
    Const SQLPassword = "#"
    Const SQLServer = "#"
    Const DBName = "#"
    Dim DBConn As String

    Dim cn_ADO As Object, cmd_ADO As Object
    Set cn_ADO = CreateObject("ADODB.Connection")
