load data infile 'c:\\users\\carla.desktop-9364k9k\\desktop\\alunos_1.csv' table utentes character set utf8 fields terminated ',' (nrprocesso, nome, @nome_resumido, ano, turma, @subsidio, @nome_ee, @nif, @email, @obs) set  subsidio = if(@subsidio='','nenhum',@subsidio), nome_resumido = if(@nome_resumido='',null,@nome_resumido), nome_ee = if(@nome_ee='',null,@nome_ee), nif = if(@nif = '', null,@nif),  email = if(@email='',null,@email), obs = if(@obs='',null,@obs);

thanks in advance.

you have do check cell/column value , form sql inject in mysql.

public list<object> getrecordingslistfromcsv(string csvfilelocation, string mp3filelocation, string mp3filelocation2, string savefilelocation, channelsftp sftp) {         map<string, file> recordingsfilesmap = null;         bufferedreader br = null;         list<string> errorfileslist = new arraylist<>();         list<object> templist = new linkedlist<>();         try {             csvrows = 0;             recordingsfilesmap = new linkedhashmap<>();             br = new bufferedreader(new filereader(csvfilelocation));             string line = br.readline();             scriptlog.info("\n" + csvfilelocation + " loaded. parsing file...");              while ((line = br.readline()) != null) {                  string[] csvarray = parsecsvlinetoarray(line); //                system.out.println(arrays.aslist(csvarray) + "\n\n");                 if (csvarray[0].trim().isempty()) {                     continue;                 }                 /* stuff here */                  csvrows++;              }         } catch (filenotfoundexception e) {             scriptlog.error("\n---error---\n    file not found: " + csvfilelocation);             string errorstr = "type=" + e.tostring();             errorstr += "stacktrace=" + arrays.tostring(e.getstacktrace());             scriptlog.error(errorstr);         } catch (ioexception e) {             string errorstr = "type=" + e.tostring();             errorstr += "stacktrace=" + arrays.tostring(e.getstacktrace());             scriptlog.error(errorstr);         } {             if (br != null) {                 try {                     br.close();                 } catch (ioexception e) {                     system.out.println(e.tostring());                 }             }         }
