概述
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。

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; }
}
