Re: [fpc-devel] TFieldDef.Size vs TField.Size
One way is: TField.Size := (TFieldDef.Size div 2) if it's a WideString, and div 4 if unicode is enabled. Or the TDataset descendant has to correct the value for WideStrings when creating fields. (How?) Very simple/primitive Idea No1: add property DataSize: integer read GetDataSize write FDataSize; into TFieldDef class add next parameter ADataSize to Constructor TFieldDef.Create(AOwner: TFieldDefs; const AName: string; ADataType: TFieldType; ASize: Integer; ARequired: Boolean; AFieldNo: Longint ADataSize: Integer=0); which is used in every TSQLConnection descendant to create fielddefs So connectors can supply ASize=character length and also ADataSize=byte length , which they require to write/read character data into local buffer (each connector should be aware of this information ... i.e. encoding of character data which exchanges with DB engine) If not specified , then default =0 means use ASize+1 for ftString, (ASize+1)*2 for ftWideString ... for backward compatibility, for most others datatypes ignore it (because they are internaly stored in fixed length data structures). Each TSQLConnection has CharSet property and each DB engine supports limited number of connection charsets. So SQLConnection can read CharSet property and determine character width. For example if CharSet='UTF-8' then char_width:=3 (or 4) if CharSet='UCS-2' then char_width:=2 if CharSet='UTF-16' then char_width:=4; So with conjuction with Column size (ASize) can easy compute buffer size (ADataSize) or Constructor TFieldDef.Create(AOwner: TFieldDefs; const AName: string; ADataType: TFieldType; ASize: Integer; ARequired: Boolean; AFieldNo: Longint ACharEncoding: TCharEncoding); TCharEncoding=(cheUnknown, cheAnsi, cheUTF8, cheUTF16); and then ADataSize can be computed inside TFieldDef.Create and stored into FDataSize for later usage.(as I wrote before TFieldDef.GetDataSize will replace TCustomBufDataset.GetFieldSize) Laco. ___ fpc-devel maillist - fpc-devel@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-devel
