I am using Delphi 5 with ODBC and BDE to connect to SQL Server. I use cached updates in a few places and am getting access violations I never had with Sybase. I close all my queries when a screen is closed and now I get access violations for closing different queries depending on whether or not updates have been made to the cached updated query. Any idea why this is happening? Thanks. Back to top Kevin Frevert Guest Posted: Fri Apr 13, 2007 10:37 pm    Post subject: Re: Access Violations Rhea, What is the error?

Any idea why this is happening? Thanks. I got the same problem. The error message is an Access error in memory adresses but no info where the error occurs. I could the error trace back to an TQuery object but no idea whats wrong with it. The CPU Windows (Delphi Debugger) show everytime the same position of the error. I'm not very with ASM but it occurs some lines after a call command for a lock at idodbc32. So maybe it seems to be an error in the odbc driver of MSSQL. I have the native one installed to but though I get the same error here so that the native driver also a kind of odbc. Hope someone know more and maybe an answer. greets Sebastian --- posted by geoForum on http://delphi.newswhat.com Back to top Del Murray Guest Posted: Fri Apr 20, 2007 3:53 pm    Post subject: Re: Access Violations IIRC .. Sql Server 7 and above dont fit well with BDE. WHy not switch to ADO and use OLD DB lib for SQL server and it will work fine..

WHy not switch to ADO and use OLD DB lib for SQL server and it will work fine.. Not a bad idea, but i have a very old big app here and that would not be worth to change to ADO cause the BDE etc is wired too deep and it runs also on Oracle which the app came working from. I port the datamodel to MSSQl and that took about 4 weeks. But the change to ADO would be a killer argument against it. :( --- posted by geoForum on http://delphi.newswhat.com Back to top Rhea Grason Guest Posted: Wed Apr 25, 2007 12:41 am    Post subject: Re: Access Violations I will switch to ADO eventually but not enough time right now.
