Database tools for .NET

Work across databases
with less .NET plumbing.

Keep your SQL. DubUrl handles provider resolution,
dialect selection, and query execution.

C# Using DubUrl

// ConnectionString contains your database URL.
var db = new DatabaseUrl(ConnectionString);
var fullName = db.ReadScalarNonNull<string>(
    new SelectFirstCustomer());

One C# call. The SQL for your database.

SelectFirstCustomer.mssql.sql

select [FullName] from [Customer]
where [CustomerId]=1

SelectFirstCustomer.pgsql.sql

select "FullName" from "Customer"
where "CustomerId"=1

Embedded query resources are selected for the target dialect.

Pass a database URL. DubUrl resolves the configured ADO.NET provider and builds its connection string.

Make your first connection

Choose dialect-specific SQL

Keep SQL in embedded resources. DubUrl selects the query for your database dialect at runtime.

Explore the query API

Read results with less code

Read scalar values or stream rows through a consistent API, with less command and reader boilerplate.

Execute your first query

Define schemas. Generate database-specific SQL.
