Build Status

Meet Donald.

If you're a programmer and have used a database, he's impacted your life in a big way.

This library is named after him.

Getting Started

If you came looking for an ORM, this is not your light saber. May the force be with you.

Donald is a library that aims to make working with ADO.NET a little bit simpler.

Providing basic functional wrappers for the IDbCommand methods ExecuteNonQuery(), ExecuteScalar() & ExecuteReader().

Install the Donald NuGet package:

PM>  Install-Package Donald

Or using the dotnet CLI

dotnet add package Donald

Example

A script is worth a thousand words:

// ------------
// An example using SQL Server
// ------------
open System.Data.SqlClient

let connectionString = 
    "Server=myServerAddress;Database=myDataBase;Trusted_Connection=True;"


// Created our strongly typed DbConnectionFactory
let connectionFactory : DbConnectionFactory = 
    fun _ -> new SqlConnection(connectionString) :> IDbConnection


// Define our model
type Author = 
    {
        AuthorId : int
        FullName : string
    }
    // Not mandatory, but helpful
    static member fromReader (rd : IDataReader) = 
        {
            AuthorId = rd.GetInt32("author_id")  // IDataReader extension method
            FullName = rd.GetString("full_name") // IDataReader extension method
        }


// Find author's by name
let findAuthor search =
    use conn = createConn connectionFactory

    query
         "SELECT author_id, full_name
         FROM   author
         WHERE  full_name LIKE @search"
        [ newParam "search" search ]
        Author.fromReader
	conn


// Create a new author
let insertAuthor fullName =
    use conn = createConn connectionFactory
    use tran = beginTran conn // Base function's are transaction-oriented
    
    let authorId = 
        tranScalar // ExecuteScalar() within scope of transaction
            "INSERT INTO author (full_name) VALUES (@full_name);
             SELECT SCOPE_IDENTITY();"
            [ newParam "full_name" fullName]
            Convert.ToInt32 // Any obj -> int function would do here
	    tran

    commitTran tran

    authorId 


// Update an existing author
let updateAuthor author =
    use conn = createConn connectionFactory
    use tran = beginTran conn 

    tranExec // ExecuteNonQuery() within scope of transaction
        "UPDATE author SET full_name = @full_name WHERE author_id = @author_id"
        [ 
            newParam "author_id" author.AuthorId
            newParam "full_name" author.FullName
        ]
        tran

    commitTran tran // safely commit transaction


// Retrieve author by id
let getAuthor authorId =
    use conn = createConn connectionFactory

    querySingle // Returns Option<Author>
        "SELECT author_id, full_name
         FROM   author
         WHERE  author_id = @author_id"
         [ newParam "author_id" authorId ]
         Author.fromReader 
	 conn
