Create RecID index on tables with Created/Modified DateTime fields

2009-06-19T22:58:00Z

When you Insert into a table with CreatedDateTime field on SQL 2005, the following SQL statement will be issued immediately following the Insert: SELECT CreatedDateTime From <table> WHERE RecID=<recid> AND DataAreaId=<dataareaid> When you Update a table with ModifiedDateTime field on SQL 2005, the...(read more)

Debugging X++ Object Leaks

2008-07-04T20:40:00Z

One of the most important aspects of writing managed code that interacts with AX through the Business Connector is cleaning up objects. Each AxaptaObject and AxaptaTable must have dispose called on it before going out of scope, or we’ll leak the object on the server with no way to clean it up. AxaptaObject and AxaptaTable do not implement Finalizers, so the onus is on the consumer of these APIs to do proper cleanup. If a session logs off, all of its objects are cleaned up regardless of whether or...(read more)
