  • ServiceStack.OrmLite

    LINQ很強大,不過有一點做不了,就是批量更新,刪除。而這個框架就實現了這個功能,令我喜出望外。

    下載for sql server
    PM> Install-Package ServiceStack.OrmLite.SqlServer -Version 4.0.30

    1.Dictionary returns a Dictionary made from the first two columns:

    Dictionary<int, string> trackIdNamesMap = db.Dictionary<int, string>(
        "select Id, Name from Track")
    

    2.Lookup returns an Dictionary<K, List<V>> made from the first two columns:

    Dictionary<int, List<string>> albumTrackNames = db.Lookup<int, string>(
        "select AlbumId, Name from Track")
    


    3.Reference Support, POCO style

    OrmLite lets you Store and Load related entities in separate tables using [Reference] attributes in primary tables in conjunction with {Parent}Id property convention in child tables, e.g:

    public class Customer
    {
        [AutoIncrement]
        public int Id { get; set; }
        public string Name { get; set; }
    
        [Reference] // Save in CustomerAddress table
        public CustomerAddress PrimaryAddress { get; set; }
    
        [Reference] // Save in Order table
        public List<Order> Orders { get; set; }
    }
    
    public class CustomerAddress
    {
        [AutoIncrement]
        public int Id { get; set; }
        public int CustomerId { get; set; } //`{Parent}Id` convention to refer to Customer
        public string AddressLine1 { get; set; }
        public string AddressLine2 { get; set; }
        public string City { get; set; }
        public string State { get; set; }
        public string Country { get; set; }
    }
    
    public class Order
    {
        [AutoIncrement]
        public int Id { get; set; }
        public int CustomerId { get; set; } //`{Parent}Id` convention to refer to Customer
        public string LineItem { get; set; }
        public int Qty { get; set; }
        public decimal Cost { get; set; }
    }
