Why does StringField.Size change after opening smartquery?

[jz]

I've got table with varchar2 field (length - 10 chars), why does Size property of StringField (field of smartquery) change always to 40 (i tried with 15 chars, it was 60 then, so it's always multiplied 4 times).

Size property of TStringField is size of the field in bytes. So if your database have multibytes character set, TStringField.Size contains size in characters multiplied on size of one character.
