Pseudo-Columns

The RSSBus ADO.NET Provider for QuickBooks offers some input-only fields in the SELECT Statements. These fields, called pseudo-columns, do not appear as regular columns in the results, yet may be specified as part of the WHERE clause. Pseudo-columns allow access to additional features from QuickBooks.

  SELECT * FROM Customers WHERE StartModifiedDate = 2011-11-11

Limitations

The SQL Syntax for the SELECT statement has the following limitations in this version (when compared to tools like SQL Server):

• Table joins are not supported, so a query can only reference a single table in the FROM clause.
• GROUP BY, HAVING clauses and nested statements are not supported.
• Scalar or aggregation functions are not supported.
