如何在MS SQL Server 2014中創建新的數據類型？

Question

在我的應用程序的服務器端，我使用MS SQL Server 2014 Express。在客戶端我有C＃WPF應用程序，我有以下枚舉類型：

/// <summary> 
/// User authorization level. 
/// </summary> 
public enum UserAuthorizationLevel 
{ 
    /// <summary> 
    /// Only visual inspection is allowed (the first lower level). 
    /// </summary> 
    Inspection, 
    /// <summary> 
    /// Some settings in apparatus are allowed (the second level). 
    /// </summary> 
    SettingDeviceParametersApplied, 
    /// <summary> 
    /// Some more setting in apparatus are allowed than in the second level (the third level). 
    /// </summary> 
    Maintenance, 
    /// <summary> 
    /// Apparatus manufacturer level - full access is allowed (the highest level). 
    /// </summary> 
    Manufacturer 
} 

我可以創建這種類型的服務器端（在MS SQL Server數據庫），並使用這種類型的類型在數據庫表中的字段？

我建議你去看看這個：Best method to store Enum in Database

你有什麼是枚舉，而不是一個類型。枚舉轉換爲類型Int。所以你會有這樣的事情：

/// <summary> 
/// User authorization level. 
/// </summary> 
public enum UserAuthorizationLevel 
{ 
    /// <summary> 
    /// Only visual inspection is allowed (the first lower level). 
    /// </summary> 
    Inspection = 0, 
    /// <summary> 
    /// Some settings in apparatus are allowed (the second level). 
    /// </summary> 
    SettingDeviceParametersApplied = 1, 
    /// <summary> 
    /// Some more setting in apparatus are allowed than in the second level (the third level). 
    /// </summary> 
    Maintenance = 2, 
    /// <summary> 
    /// Apparatus manufacturer level - full access is allowed (the highest level). 
    /// </summary> 
    Manufacturer = 3 
}
