nicht gefunden (Fehlermeldung Errcode: 22 "Invalid argument")

Question

Ich versuche, Daten aus CSV-Datei zu laden, indem

try (Connection connection = DBConnection.getConnection()) { 
      String loadQuery = "LOAD DATA INFILE '" + path.toAbsolutePath() 
        + "' INTO TABLE persons FIELDS TERMINATED BY ','" 
        + " LINES TERMINATED BY '\n' (PersonID, FirstName, City) "; 
      System.out.println(loadQuery); 
      Statement stmt = connection.createStatement(); 
      stmt.execute(loadQuery); 
     } catch (Exception e) { 
      e.printStackTrace(); 
     } 

aber ich erhalte die folgenden Fehler

LOAD DATA INFILE 'D:\temp\fileupload.csv' INTO TABLE persons FIELDS TERMINATED BY ',' LINES TERMINATED BY ' 
' (PersonID, FirstName, City) 
java.sql.SQLException: File 'D:\ empfileupload.csv' not found (Errcode: 22 "Invalid argument")

Wie soll ich das lösen? jede Hilfe wird geschätzt.

Answer 1

Ich denke, Sie sollten den umgekehrten Schrägstrich in \n in Ihrer LOAD DATA Aussage zu entkommen Java zu sagen, dass es sich um einen wörtlicher \n ist und kein echter Zeilenumbruch:

String loadQuery = "LOAD DATA INFILE '" + path.toAbsolutePath() 
       + "' INTO TABLE persons FIELDS TERMINATED BY ','" 
       + " LINES TERMINATED BY '\\n' (PersonID, FirstName, City) "; 

Wie andere gesagt haben, sollten Sie auch die entkommen Pfad zu Ihrer Datei.
