在Windows 8和Delphi XE3上使用SQL Server的ADO中，什么会导致“游标操作冲突”错误？

Question

I'm using Embarcadero Delphi XE3 on Windows 8 and I'm trying to connect with SQL Server 2000.

My program used to work correctly when I was using Delphi 2007 on Windows 7, but now whenever I do transaction (Update, Insert, Delete) it gives me an error message saying "Cursor Operation Conflict" and continue working (commit the transaction).

I'm using TADOConnection to connect with the server and I use TADODataSet to do transactions. I use TADODataSet.Insert / TADODataSet.Edit / TADODataSet.Post / TADODataSet.Delete to do the transactions.

I couldn't post any piece from the code because it is general problem.

I would like to know what may cause this error to be able to debug my code and make sure that I'm not doing any wrong....

The error only appears when I use clUseServer in TADODataSet.CursorLocation property.

Answer 1

i had the same error with some VB6 code, it even happened when i used a disconnected adodb.recordset

my solution was to create an entirely separate connection (to the same server) for my record set which seemed to resolve my issue

i don't know much about delphi but i thought it could possibly help
