we use Delphi 7 and the SDAC Version 4.50.
We create a wrapper class the connect with the Database and this class has the property query with is a TMSQuery.
We use this code snippet to set a blob field to null
Code: Select all
With the ADO implementation of Delphi is works fine, but with the SDAC component the NULL value wouldn't set to the database.
Have enyone an idea, were the problem can be?
