Unidac serious bug in Delphi2009

[coolzew]

Hi, Developer,

Do you know there is a the difference in Delphi2009: TField.AsString and TField.Value,
I tested it and Result is :
----------------------------------------------------
function TStringField.GetAsString: string;
begin
Result := string(GetAsAnsiString);
end;
----------------------------------------------------
----------------------------------------------------
function TStringField.GetAsVariant: Variant;
var S: AnsiString;
begin
if GetValue(S) then Result := S
else Result := Null;
end;
----------------------------------------------------
So ,you know VarType(TField.Value) = 256 VarType(TField.AsString) = 258,
Please check your code which prepare Params before execute sql.
When I run in delphi2009, then Param Size is not enough,
now is : "中国" size is varchar(2),
to tell your the truth the size is varchar(4)

I am looking forward to hearing from you.
Thank you in advance.

Please describe what is the problem that occurs in your application. Which provider (Oracle, InterBase, etc.) are you using?

Step1.
create a table in MS SQL SERVER:
Create table tblDEMO ( AField varchar(10))

Step2.
Under Delphi2009, Use TUniQuery to Open this table tblDEMO,
Data Control use DBGrid.

Step3.
In DBGrid, append a record enter value '中国', then post it.

Step4
Refresh or reopen the table tblDemp, Only '中' stored.

My OS (XP) lauguage is simplify-chinese .
