we’ve got a real confusing problem. We’re trying to test an SQL Bulk Load using a little app we’ve written that passes in the datafile XML, the schema, and the SQL database connection string.
It’s a very straight-forward app, here’s the main part of the code:
SQLXMLBULKLOADLib.SQLXMLBulkLoad4Class objBL = new SQLXMLBULKLOADLib.SQLXMLBulkLoad4Class();
objBL.ConnectionString = "provider=sqloledb;Data Source=SERVER\\SERVER; Database=Main;User Id=Username;Password=password;";
objBL.BulkLoad = true;
objBL.CheckConstraints = true;
objBL.ErrorLogFile = "error.xml";
objBL.KeepIdentity = false;
objBL.Execute("schema.xml", "data.xml");
As you can see, it’s very simple but we’re getting the following error from the library we’re passing this stuff to: Interop.SQLXMLBULKLOADLib.dll.
The message reads:
Failure: Attempted to read or write protected memory. This is often an indication that other memory has been corrupted
We have no idea what’s causing it or what it even means.
Before this we first had an error because SQLXML4.0 wasn’t installed, so that was easy to fix. Then there was an error because it couldn’t connect to the database (wrong connection string) – fixed. Now there’s this and we are just baffled.
Thanks for any help. We’re really scratching our heads!
I am not familiar with this particular utility (Interop.SQLXMLBULKLOADLib.dll), but have you checked that your XML validates to its schema .xsd file? Perhaps the dll could have issues with loading the xml data file into memory structures if it is invalid?
