SQLite中文排序

定义一个类：

using System.Data.sqlite;

namespace DAL
{
    /// <summary>
    /// sqlite中文排序
    </summary>
    [sqliteFunction(FuncType = FunctionType.Collation,Name = "PinYin")]
    public class sqlitePinYingSort : sqliteFunction
    {
        override int Compare(string x,string y)
        {
            return .Compare(x,y);
        }
    }
}

View Code

在Global.asax.cs文件的Application_Start方法中添加如下代码：

sqliteFunction.RegisterFunction(typeof(sqlitePinYingSort)); //使sqlite支持中文排序

sql代码：

select ct.* 
from mas_channel_type ct 
where ct.pId=-1
order by ct.typeName COLLATE PinYin
