我有这种方法从CSV文件导入数据。但该方法仅添加PID。任何消化来修复这个??

    public void importData(){
        try{
            Import path = new Import();
            String filename = path.getFileName();
            con = DriverManager.getConnection("jdbc:mysql://localhost:3306/test");
            st = con.createStatement(rs.TYPE_SCROLL_SENSITIVE, rs.CONCUR_UPDATABLE);
            String query = "LOAD DATA LOCAL INFILE '" + filename + "' INTO TABLE Pacient (PID, Nume,Prenume, Varsta, CNP, Adresa);";
            st.execute(query);
        }
        catch (SQLException | HeadlessException e){
            e.printStackTrace();
        }
        catch (Exception e){
            e.printStackTrace();
            st = null;
        }
    }

您尝试使用默认[加载数据]选项加载文件。您尝试上传的csv文件可能使用不同的格式，例如不同的FIELD Enclosed By，或不同的TERMINATED By或不同的LINE TERMINATED By选项。以下是转储csv和amp;的示例加载csv文件。请检查您的csv文件格式＆amp;用不同的选项验证。

-- -- To dump sql data to csv file
SELECT * 
FROM test.yourTableName
INTO OUTFILE 'C:/test/yourTableName.csv'
FIELDS ENCLOSED BY '"' TERMINATED BY ';' ESCAPED BY '"'
LINES TERMINATED BY '\r\n';


-- -- To load data to sql database from csv
LOAD DATA INFILE 'C:/test/yourTableName.csv' INTO TABLE test.yourTableName
 FIELDS ENCLOSED BY '"' TERMINATED BY ';' ESCAPED BY '"'
LINES TERMINATED BY '\r\n';
