定义GMAxCountryCurrency_View的代码如下：
SELECT dbo.GMAx_Contry.ContryName, dbo.GMAx_Currency.CurrencyName, dbo.GMAx_ContryCurrency.ContryID, dbo.GMAx_ContryCurrency.CurrencyID FROM dbo.GMAx_Contry INNER JOIN dbo.GMAx_ContryCurrency ON dbo.GMAx_Contry.ContryID = dbo.GMAx_ContryCurrency.ContryID INNER JOIN dbo.GMAx_Currency ON dbo.GMAx_ContryCurrency.CurrencyID = dbo.GMAx_Currency.CurrencyID
