SQL Server bit數據類型

bit值保存為1/0，1代表true，0代表false
讀取數據庫數據時，可以直接用bool型讀取該字段，會直接轉換為true/false

數據庫表結構

CREATE TABLE [dbo].[BitTable]( [PKID] [int] IDENTITY(1,1) NOT NULL, [IsDelete] [bit] NULL, PRIMARY KEY CLUSTERED ( [PKID] ASC )WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY] ) ON [PRIMARY] 

實體類BitModel

public class BitModel
{
    public int PKID { get; set; }
    public bool IsDelete { get; set; }
}

讀取數據
采用dapper，封裝方法

public class DbManager<T> where T : class
{
    private static DbManager<T> instance;
    private static object _lock = new object();
    private SqlConnection connection;
    public static DbManager<T> Instance
    {
        get
        {
            lock (_lock)
            {
                if (instance == null)
                {
                    instance = new DbManager<T>();
                }
             }
            return instance;
        }
    }

    public DbManager()
    {
        connection = new SqlConnection("Server=;DataBase=;Uid=;pwd=;");
        connection.Open();
    }

    public IEnumerable<T> QueryBySQL(string sql)
    {
        return connection.Query<T>(sql);
    }

    public bool ExecuteOne(string sql)
    {
        if (connection.Execute(sql) != 0)
            return true;
        return false;
    }
}

public ActionResult Bit()
{
    List<BitModel> list = new BLL.AboutDBManager().GetBitModel();
    return View(list);
}

顯示數據

<div>
    <table>
        <thead>
            <tr>
                <th>主鍵</th>
                <th>是否刪除</th>
            </tr>
        </thead>
        <tbody>
            @{ 
                foreach(var item in Model)
                {
                    <tr>
                        <td>@item.PKID</td>
                        <td>@item.IsDelete</td>
                    </tr>
                }
            }
        </tbody>
    </table>
</div>
