DBit

A lightweight database API with performance and ease-of-use in mind

Execute Querys

//returns a dynamic object
dynamic contact = dbit.Query("SELECT TOP 1 * FROM CONTACT").Populate();

//returns a IEnumerable<dynamic>
IEnumerable<dynamic> contacts = dbit.Query("SELECT * FROM CONTACT").PopulateModels();

//returns an object of type T
Contact contact = dbit.Query("SELECT TOP 1 * FROM CONTACT").Populate<Contact>();

//returns a IEnumerable<T>
IEnumerable<Contact> contacts = dbit.Query("SELECT TOP 1 * FROM CONTACT").PopulateModels<Contact>();

//get a specific value (datatype) from the table
int contactID = dbit.Query("SELECT TOP 1 ID * FROM CONTACT").Populate();

Execute Stored Procedures

//returns a dynamic object
dynamic contact = dbit.StoredProcedure("usp_GetContacts").Populate();

//returns a IEnumerable<dynamic>
IEnumerable<dynamic> contacts = dbit.StoredProcedure("usp_GetContacts").PopulateModels();

//returns an object of type T
Contact contact = dbit.StoredProcedure("usp_GetContacts").Populate<Contact>();

//returns a IEnumerable<T>
IEnumerable<Contact> contacts = dbit.StoredProcedure("usp_GetContacts").PopulateModels<Contact>();

Add parameters to Querys or Stored Procedures

//Returns an object of type T
var contact = dbit.Query("SELECT * FROM CONTACT WHERE ID = @ID AND NAME = @NAME")
                    .AddParameter("@ID", 8128)
                    .AddParameter("@NAME", "dbit")
                    .Populate<Contact>();
                    
//Supports arrays
var contact = dbit.Query("SELECT TOP 1 * FROM CONTACT WHERE ID IN ( @IDS )")
                      .AddParameter("@IDS", new int[] { 8228, 500, 404})
                      .Populate<Contact>();

Return the int-result

var result = dbit.Query("SELECT * FROM CONTACT WHERE ID = @ID AND NAME = @NAME")
                    .AddParameter("@ID", 8128)
                    .AddParameter("@NAME", "dbit")
                    .Execute();

Get the returned dataset

DataSet ds = dbit.Query("SELECT * FROM CONTACT WHERE ID = @ID AND NAME = @NAME")
                    .AddParameter("@ID", 8128)
                    .AddParameter("@NAME", "dbit")
                    .ExecuteDataSet();

Performance tests

All tests were performed on a Windows 7 64-bit machine, with Intel i5 2.67GHz and 8GB RAM. Connecting to a local SQL 2012 Server and doing lookups against a [Contact] table which has 37 columns, and contains 380207 records.

Code	Duration (Best)
.Populate();	33ms
.Populate<T>();	35ms
.PopulateModels();	33ms
.PopulateModels<T>();	38ms

The exact code I ran to test this was with

    Stopwatch sw = new Stopwatch();

    DBit dbit = new DBit(new SqlConnection(ConfigurationManager.ConnectionStrings["DBConnection_DEV"].ToString()));

    sw.Start();
    
    /*  dbit   */
    //dynamic c1 = dbit.Query("SELECT TOP 1 * FROM [CONTACT]").Populate();
    //dynamic c2 = dbit.Query("SELECT TOP 1 * FROM [CONTACT] WHERE ID = @ID").AddParameter("@ID", 15318).Populate();
    //Contact c3 = dbit.Query("SELECT TOP 1 * FROM [CONTACT]").Populate<Contact>();
    //IEnumerable<dynamic> c4 = dbit.Query("SELECT TOP 100 * FROM [CONTACT]").PopulateModels();
    //IEnumerable<Contact> c5 = dbit.Query("SELECT TOP 100 * FROM [CONTACT]").PopulateModels<Contact>();

    sw.Stop();
    Console.WriteLine("Executed in: {0} (minutes, seconds, millisecs)", sw.Elapsed.ToString("mm\\:ss\\.fff"));
