Hi, The goal, I have a text file with words and I want to export in a FDMemTable words with length between 4 and 12 ? I don't know how to get the value in onWriteRecord event, is there a way to ? I can get the value in the OnWriteValue one but fired after onWriteRecord it's unusefull. Any hints (not involving a localsql DELETE)

I am using a TFDMemTable to import text data. When processing comma delimited files with double-quoted values an error occurs when the last line in the file does not have a line feed. To reproduce this problem create a text file with the following values in notepad: "name","date","amount" "Alpha","1/1/2021","100" "Bravo","1/2/2021","200" "Charlie","1/3/2021","300" Make sure you save the file with the final cursor at the end of the "Charlie" line. The following error will occur on BatchMove.Execute; The error does not occur if double-quote characters are not used. The error does not occur if you add a line feed so the cursor is on the line after "Charlie" when the file is saved. myTable := TFDMemTable; myReader := TFDBatchMoveTextReader; myWriter := TFDBatchMoveDataSetWriter; myMover := TFDBatchMove; procedure Test (const p_FileName: String); var // --- Added in attemp to bypass the issue I: Integer; // --- Added in attemp to bypass the issue begin myReader.FileName := p_FileName; for i := 0 to myReader.Datadef.Fields.Count-1 do // --- Added in attemp to bypass the issue myReader.Datadef.Fields.DataType := atString; // --- Added in attemp to bypass the issue myReader.DataDef.WithFieldNames := True; myWriter.DataSet := myTable; myWriter.Optimise := False; myMover.Reader := myReader; myMover.Writer := myWriter; myMover.GuessFormat; myMover.Analyze := [taDelimSep, taHeader, taFields]; myMover.AnalyzeSample := 50; myMover.Execute; end; The files being processed are automatically obtained from other systems. We cannot control the presence of the linefeed without modifying the received file. Can you please advise on how to handle this issue?
