Public Methods

Method	Description
All ( string where = "", string orderBy = "", int limit, string columns = "*" ) : IEnumerable	Returns all records complying with the passed-in WHERE clause and arguments, ordered as specified, limited (TOP) by limit.
BeforeDelete ( dynamic item ) : bool
BeforeSave ( dynamic item ) : bool
BuildCommands ( ) : List	Builds a set of Insert and Update commands based on the passed-on objects. These objects can be POCOs, Anonymous, NameValueCollections, or Expandos. Objects With a PK property (whatever PrimaryKeyField is set to) will be created at UPDATEs
CreateDeleteCommand ( string where = "", object key = null ) : DbCommand	Removes one or more records from the DB according to the passed-in WHERE
CreateFrom ( NameValueCollection coll ) : dynamic	Creates a new Expando from a Form POST - white listed against the columns in the DB
CreateInsertCommand ( dynamic expando ) : DbCommand
CreateUpdateCommand ( dynamic expando, object key ) : DbCommand	Creates a command for use with transactions - internal stuff mostly, but here for you to play with
DefaultTo ( string key, object value, dynamic item ) : void
DefaultValue ( dynamic column ) : dynamic	Gets a default value for the column
Delete ( object key = null, string where = "" ) : int	Removes one or more records from the DB according to the passed-in WHERE
Deleted ( dynamic item ) : void
DynamicModel ( ConnectionStringSettings connectionStringSettings, string tableName = "", string primaryKeyField = "" ) : System
DynamicModel ( string connectionStringName, string tableName = "", string primaryKeyField = "", string descriptorField = "" ) : System
Execute ( DbCommand command ) : int
Execute ( IEnumerable commands ) : int	Executes a series of DBCommands in a transaction
Execute ( string sql ) : int
GetPrimaryKey ( object o ) : object	If the object passed in has a property with the same name as your PrimaryKeyField it is returned here.
HasPrimaryKey ( object o ) : bool	Conventionally introspects the object passed in for a field that looks like a PK. If you've named your PrimaryKeyField, this becomes easy
Insert ( object o ) : dynamic	Adds a record to the database. You can pass in an Anonymous object, an ExpandoObject, A regular old POCO, or a NameValueColletion from a Request.Form or Request.QueryString
Inserted ( dynamic item ) : void
IsValid ( dynamic item ) : bool
ItemAsDictionary ( ExpandoObject item ) : object>.IDictionary	This will return an Expando as a Dictionary
ItemContainsKey ( string key, ExpandoObject item ) : bool
KeyValues ( string orderBy = "" ) : object>.IDictionary	This will return a string/object dictionary for dropdowns etc
Open ( ConnectionStringSettings connectionStringSettings ) : DynamicModel
Open ( string connectionStringName ) : DynamicModel
OpenConnection ( ) : DbConnection	Returns and OpenConnection
Paged ( string where = "", string orderBy = "", string columns = "*", int pageSize = 20, int currentPage = 1 ) : dynamic	Returns a dynamic PagedResult. Result properties are Items, TotalPages, and TotalRecords.
Paged ( string sql, string primaryKey, string where = "", string orderBy = "", string columns = "*", int pageSize = 20, int currentPage = 1 ) : dynamic
Query ( string sql ) : IEnumerable	Enumerates the reader yielding the result - thanks to Jeroen Haegebaert
Query ( string sql, DbConnection connection ) : IEnumerable
Save ( ) : int	Executes a set of objects as Insert or Update commands based on their property settings, within a transaction. These objects can be POCOs, Anonymous, NameValueCollections, or Expandos. Objects With a PK property (whatever PrimaryKeyField is set to) will be created at UPDATEs
