Seekwell

Stupid simple database access for .net 2.0 and up. Given a sql command and optional parameters the Query<T> and QueryAsync<T> methods will return an IEnumerable<T> and Task<IEnumerable<T>> respectively. ExecuteScalar and ExecuteScalarAsync are useful for fire and forget queries and also for inserting data and returning a scope_identity.

Install

To install Seekwell, run one of the following commands in the Package Manager Console

PM> Install-Package Seekwell.Async

If you're in a pre .net 4.5 project run this command instead

PM> Install-Package Seekwell

Quick Start Usage

var command = new Command();
var allPeople = await command.QueryAsync<Person>("SELECT * FROM People with (nolock)");

With Parameters

var males = await command.QueryAsync<Person>(
    "SELECT * FROM People with (nolock) where Gender = @Gender",
    new { Gender = "M" });

Inserts

var person = new Person
{
    Name = "John Smith",
    Gender = "M"
};
person.Id = await command.ExecuteScalarAsync(
    @"Insert into People (Name, Gender) Values(@Name, @Gender); 
        select Scope_identity();",
    new {
        Name = person.Name,
        Gender = person.Gender
    });

Can I do non async?

Absolutely. Seekwell is sensitive to the fact that real world projects often have red tape involved in upgrading .net versions. That's why the main Seekwell project is written in 2.0 and the async operations are provided as extension methods in a 4.5 project.

var people = command.Query<Person>("SELECT * FROM People with (nolock)");

What is the default timeout?

The default timeout for a query is 30 seconds. You can change that at anytime by setting the Timeout property on the Command object.

What about IDisposable?

No part of this code requires us to implement IDisposable which means you don't have to worry about using statements.

How does it know my connection string?

While you certainly can pass a connection string into the Command constructor, the default constructor pulls the first connection string found in your config file where the name isn't "LocalSqlServer". This was done to reduce machine.config connection string frustration.
