Need to save a blob from an ADO db field to a file
Hi,
I've tried the following while attempting to save a blob field off to a file.
The blob contains a PDF file.

procedure test;
var
qry, f, value: OleVariant;
sql: string;
i: Integer;
val: char;
begin
sql := 'select FILE_CONTENTS from PA_DOCUMENTS';
qry := Query(SQL, 1);
value := qry.Field[0].AsVariant;
// qry.FieldByNam
f := aqFile.OpenBinaryFile('c:\test.pdf', aqFile.faWrite, true);
for i:= 1 to Length(value) -1 do
begin
//Log.Message(value);
val := ord(value);
log.message(VarToStr(val) + ' ' + VarToStr(value));
f.Write(val);
end;
f.Close;
end;
The above code fails when it trys to write out what looks like a non-ASCII character (the pound symbol).
Any bright ideas about how to do this?
