# 2971 Cannot Migrate Certain Older DBISAM Tables with BCD Columns to ElevateDB

I've just had a customer report that they're receiving migration errors. I got them to email their database (thinking it was something they were doing wrong) and in fact I can't migrate their database either!

I'm trying to migrate it using the UNICODE edbmigratedbisam4.dll (2.02b10).

In my application (using ADO.NET) the Exception thrown during the migratration process is "Invalid Currency Value".

When I try to migrate this table in EDB Manager, the error reported is "Invalid floating point operation".

I ran a DBISAM Repair on the table (in case it was corrupted) but no difference. So far this is the only customer who has reported a problem.

Comments

This problem was caused by an incompatibility between the BCD to currency conversion in BDS 2006 or higher vs. older versions of Delphi. The BDS 2006 and higher versions were not able to cope with the decimal values used by older versions of Delphi. A gracious thanks to Bruno Krayenbuhl for the fix to this issue.

Resolution

Fixed Problem on 4/3/2009 in version 2.02 build 11
