    ya the option is QString only.
    You asked me to check the "if" by adding it after the loop. By adding it after the loop only becomes infinite.

      Should this help?

      @
      int pos1 = option.indexOf('|');
      if (pos1 != -1)
      {
      stmt1 = option.left(pos1);

      int pos2 = option.indexOf('\\', pos1);
      if (pos2 != -1)
      {
          phrase = option.mid(pos1, pos2 - pos1);
      }
      

      else
      {
      // there is no '|' symbol in option
      }
      @

          You shouldn't use a single backslash in option string, because it will be processed as '.' in second case.
          So, before processing, replace single backslashes with doubled or select another symbol

            This means whether you are asking me to use double backslash in the phrase itself or at the end of last stmt i've to put double backslash.

              By trying with this code,

              @
              1.int pos1 = option.indexOf('|');
              2.if (pos1 != -1)
              3. {
              4. stmt1 = option.left(pos1);
              5. int pos2 = option.indexOf('\', pos1);
              7. if (pos2 != -1)
              8. {
              9. phrase = option.mid(pos1, pos2 - pos1);
              10 }
              11. else
              12. {
              13. // there is no '|' symbol in option
              14. }
              @
              I am getting this error "commitdb.cpp:1219: error: a function-definition is not allowed here before ‘{’ token" in some other functions.
              so i removed this code and compile with the the original code itself.@@

                  Ya i added }
                  Now it is not exiting from the editor and its working.
                  But, the question is entering into database finely, the answer is not entering to the database (i.e options) printing the null values for option,stmt1 and stmt2 . Also the null values are entering to database more than once

                    Sorry, I don't understand what you do you want.

                    1. Insert some values into some db?
                    2. something else?

                      no through editor i am entering the Ques and answer also
                      The xml file generates, from the xml file to database it is entering, bt the Ques is entering into the database correctly.
                      The options i.e Qt is a |cross platform\ appln framework is the Answer stmt.
                      Bt this enters the database as null value only not the stmt or phrase

                        My code is not processing statements with asterisk (*), so you should add this by yourself ;-)

                          No thats not my problem.

                          After replacing my code with the code wat u give me to replace with, the following is the table entries now.

                          The following table for Question entries

                          QNo | Question | QueLocLang | Board | Subject | Chapter | PageNo

                          4724 | What is Qt? | NULL | Tamil Nadu | EnglishI | 1 | 1

                          4725 | Who is Sachin? | NULL | Tamil Nadu | EnglishI | 1 | 1

                          The table entries for Answers is,
                          More than one time it is entering like the following

                          APNo | Statement1 | Statement2 | Option1 | QNo

                          80563 | | NULL | | 4724

                          80564 | | NULL | | 4724

                          80565 | | NULL | | 4724

                          80566 | | NULL | | 4725

                          80567 | | NULL | | 4725

                          80568 | | NULL | | 4725

                          The actual Answer table should be like,

                          APNo | Statement1 | Statement2 | Option1 | QNo

                          80563 | Qt is a | NULL | cross platform application framework | 4724

                          80564 | | is sachin | A famous crickter | 4725

                          But i am not getting like this. I am just getting the empty values for stmt1,option.

                              I've already checked my code and it works fine (actually, you can change line 9 with phrase = option.mid(pos1 + 1, pos2 - pos1); to remove leading '|').

                              Input: "Qt is a |cross platform application framework."
                              Output: stmt1 = "Qt is a "
                              phrase = ""cross platform application framework"

                                I tried by that too phrase = option.mid(pos1 + 1, pos2 – pos1); bt nw th answer table is not get updated.
                                i.e the Questions are entering to the database, but the answers are not entering to the database in answer table.

                                  if (pos2 != -1)
                                  {
                                      phrase = option.mid(pos1, pos2 - pos1 + 1);
                                  }
                                  

                                  }
                                  else
                                  {
                                  qDebug("there is no '|' symbol in option");
                                  }

                                  qDebug("stmt1=%s, phrase=%s", qPrintable(stmt1), qPrintable(phrase));
                                  @

                                  Output: "stmt1=Qt is a , phrase=|cross platform application framework"

                                  Is this output correct for your task?

                                    The '|' and '' should not seen in the database. Otherwise the output is correct.
                                    But, the thing is i need the stmt2 also enter to the database.
                                    for eg

                                    |Lotus\ is our national flower.

                                    In the above stmt, lotus is the phrase, and is our national flower is the stmt2.
                                    That stmt2 is not entering in database.

                                    And also tried with that code, also remain the same problem, the answers are not entering into the database.

                                          So in my code instead of return -1, i replaced it by returning the index as return index.

                                          As in the switch case, in if condition i'm checking the condition as

                                          @
                                          if(option[index]=='\0')
                                          {
                                          cout<<"option[index]-----\n"<<option[index]<<endl;
                                          stmt1[j] = '\0';
                                          option[0] = '\0';
                                          //return -1; instead of this
                                          return (index); added this
                                          }
                                          @

                                          instead of this condition i replaced it as,

                                          @
                                          if(index!=-1) instead of this

                                          if((((Short *)object)->options[i])[index]!='\0') added this
                                          {
                                          query = new QSqlQuery("insert into ShAnsPts(Statement1,Statement2,Option1,QNo,PointNo,CorrectNo) values ("" + stmt1 + "", NULL,"" + phrase + ""," + temp2.setNum(qNo) + "," + temp2.setNum(((Short *)object)->ptno[i+1])+",1)");
                                          }
                                          @

                                          With the above condition what i've added it working fine.

                                          It is inserting into the Ques table and also in Ans table now. whether it is right or nt. Do you have any idea about this. Please tell me
