Power of SQL





dotConnect for FreshBooks allows you to perform SQL queries against your FreshBooks data. Use SQL statements to work with FreshBooks accounts, contacts, leads, contracts, products, campaigns opportunities, and other objects.

Our provider offers full CRUD (Create, Read, Update, and Delete) support and allows you to get FreshBooks data with SELECT statements and manage data with INSERT, UPDATE, and DELETE statements.

No need to study and use complex FreshBooks API, just use familiar SQL statements. You may use complex JOINs, WHERE conditions, etc. - all the SQL benefits, not available with FreshBooks API.

Entity Framework Support

dotConnect for FreshBooks allows you to access FreshBooks data via Entity Framework - Microsoft's recommended data access technology. It supports Entity Framework v4, v5, v6, and Entity Framework Core, and enables you to use the following Entity Framework features with FreshBooks data:

  • LINQ to Entities (no need for FreshBooks API)
  • Entity relations with lazy/eager loading
  • No need to post each edited/created object separately - a single SaveChanges() call to persist all the changed objects

dotConnect for FreshBooks provides enhanced Entity Framework support for FreshBooks data with a bundled visual designer for ORM models with Visual Studio integration - Entity Developer. Standard Visual Studio Entity Data Model designer is also supported.

How it Works

dotConnect for FreshBooks offers powerful local SQL engine for SELECT statement execution. It executes SQL statements in the following way:

Simple SQL statements are translated to FreshBooks API calls and executed on the FreshBooks side directly. However, dotConnect for FreshBooks also supports more advanced SQL features, such as SQL functions or expressions, complex WHERE conditions, joins, etc.

If you use these more advanced SQL features, dotConnect for FreshBooks queries all the data from the objects that participate in the query, and executes the statement locally.
