Question

I have a Numeric(26,10) column “x” in SQL Server 2008. When I try to read the column values using TADOQuery’s FieldByName(‘x’).AsExtended, I get an error “32,7893256547 is not a valid BCD value”.

“32,7893256547” is one of the column values.

This happens only on some computers. On those computers, When I change the windows setting “No. of digits after decimal” to 9 in region settings, then everything works fine.

I see that column is mapped to TFMTBCDField in ADOQuery.

Is it a problem with BCD conversions / formatting ? And how can I solve this problem?

Platform:
Windows 7, Delphi 2009, SQL Server 2008.

Answer 1

I had the same problem when I tried to use

ADOQuery1.FieldByName('YourField').AsString;

Solved with this:

BCDToStrf(ADOQuery1.FieldByName('YourField').AsBCD,ffFixed,11,3) ;
