}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 thisif((((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
-
First of all - print all values on the screen
Second - change SQL-query builder to the next:@
query = new QSqlQuery("insert into ShAnsPts(Statement1,Statement2,Option1,QNo,PointNo,CorrectNo) values (?, ?, ?, ?, ?, ?)");
query.addBindValue(stmt1);
query.addBindValue(QVariant(QVariant::String)); // NULL string
query.addBindValue(phrase);
query.addBindValue(temp2.setNum(qNo));
query.addBindValue(temp2.setNum(((Short *)object)->ptno[i+1]));
query.addBindValue(1);
@ -
Sorry for asking you again and again, please tell me
Instead of the following code
@
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)");
@I've to add this code
@
query = new QSqlQuery("insert into ShAnsPts(Statement1,Statement2,Option1,QNo,PointNo,CorrectNo) values (?, ?, ?, ?, ?, ?)");
query.addBindValue(stmt1);
query.addBindValue(QVariant(QVariant::String)); // NULL string
query.addBindValue(phrase);
query.addBindValue(temp2.setNum(qNo));
query.addBindValue(temp2.setNum(((Short *)object)->ptno[i+1]));
query.addBindValue(1);
@If means by adding this code it is showing the error as request for member ‘addBindValue’ in ‘query’, which is of non-class type ‘QSqlQuery
For printing the values on screen i already added the following code.
@index = parseOption(index,((Short *)object)->options[i],stmt1,phrase);
cout<<"index : "<<index<<"\n"<<stmt1<<"\n"<<phrase<<endl;
QString text11;
stmt1temp=stmt1;
cout<<"stmt1temp\n"<<stmt1<<endl;
stmt1=stmt1temp;
cout<<"stmt1\n"<<stmt1<<endl;
phrasetemp=phrase;
cout<<"phrasetemp\n"<<phrasetemp<<endl;
phrase=phrasetemp;
cout<<"phrase\n"<<phrase<<endl;@ -
- As I can see your output doesn't contain any NULL-value. So, I think you have errors somewere else... Possibly, in SQL-table (e.g. wrong field type).
- For what are you make such assignments:
@
...
stmt1temp=stmt1;
cout<<"stmt1temp\n"<<stmt1<<endl;
stmt1=stmt1temp;
...

For eg if i am entering the answer like this.
Android is a |Linux-based operating system\ designed primarily for touchscreen mobile devices.In the following code,
@
index = parseOption(index,((Short *)object)->options[i],stmt1,phrase);
cout<<"index : "<<index<<"\n"<<stmt1<<"\n"<<phrase<<endl;
@
The stmt1temp,stmt1 is considered as Android is a
As you know, the phrasetemp,phrase is the same Linux-based operating system
By the following code,@
stmt1=parseQuestion(stmt1); // function called for replacing tilde,cape symbol to angluar brackets
cout<<"stmt1--\n"<<stmt1<<endl;
stmt2temp=parseStepNo(stmt1,i,aPNo);
cout<<"stmt2temp\n"<<stmt2temp<<endl;
cout<<"\nThis is the apno value required"<<aPNo<<endl;
stmt2=stmt2temp;
cout<<"This is STatement2 value"<<stmt2<<endl;
@The stmt1 is taken for stmt2 i.e designed primarily for touchscreen mobile devices.
The assignments are mainly made for parsing the options. -
Actually i missed some thing in the previous post
index : 40
Qt is a
cross platform appln frameworkstmt1temp
Qt is a
stmt1
Qt is a
phrasetemp
cross platform appln framework
phrase
cross platform appln frameworkAfter this
text11insert into ShAnsPts(Statement1,Statement2,Option1,QNo,PointNo,CorrectNo) values ("Qt is a ", NULL,"cross platform appln framework",4816,4816,1)Then,
index : 41
Qt is a
cross platform appln framework
stmt1temp
.
stmt1
.
phrasetemp
cross platform appln framework
phrase
cross platform appln framework -
Also exactly not like that. As assigning the null values in the code for stmt1 and option it will take null values in the out put i.e when printing the output as Qt is a |cross platform appln framework.
In the above result
after printing the stmt1 Qt is a after this null value is seen. -
Instead of returning index value as -1
@
return -1;
@I returned the index itself
@
return (index);
@
Also in the case SHORT:
Instead of checking the condition for executing query for inserting into answer table,@
if(index=-1)
@I checked the condition,
@
if((((Short *)object)->options[i])[index]!='\0')
@
Now it is working fine and all the questions and answers are entering to the main xml file also to the database in the appropriate table.Thanks Lukas Geyer and thanks a lot Aleksey Okinchitc.
