Power of SQL





dotConnect for QuickBooks allows you to perform SQL queries against your QuickBooks data. Use SQL statements to work with QuickBooks 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 QuickBooks data with SELECT statements and manage data with INSERT, UPDATE, and DELETE statements.

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

Entity Framework Support

dotConnect for QuickBooks allows you to access QuickBooks 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 QuickBooks data:

  • LINQ to Entities (no need for QuickBooks 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 QuickBooks provides enhanced Entity Framework support for QuickBooks 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 QuickBooks offers powerful local SQL engine for SELECT statement execution. It executes SQL statements in the following way:

Simple SQL statements are translated to QuickBooks API calls and executed on the QuickBooks side directly. However, dotConnect for QuickBooks 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 QuickBooks queries all the data from the objects that participate in the query, and executes the statement locally.
