At line 5, the query is executed and the result is assigned to the array. When I print the elements of playerLst array only 11 player names are printed(not what I expect. It has to print 99 names since each country has 11 players and there are 9 cty's).

for(int i = 0; i<ctyLst.size();i++)
{
   queryStr = L"Select Name From Test WHERE Team ='";
   queryStr += ctyLst[i].trim();
   queryStr += L"'";
   queryStr += L"ORDER BY RANDOM() LIMIT 11";
   playerLst = SQLdb.Query(queryStr);
   for(int j = 0; j<playerLst.size();j++)
   {
      printf("%s \n",playerLst[j].c_str());
   }

I wonder why this printf statement:
printf("No.of Players in the List: %d \n",playerLst.size()); prints 11 even if it outputs 99 unique names. It has to print 99 only?
If I give printf inside the for loop it prints No. Players as 11 at each iteration.

for(int i = 0; i<ctyLst.size();i++)

   queryStr = L"Select Name From Test WHERE Team ='";

   array<stringc> playersTmpLst = SQLdb.Query(queryStr);
   
   // !!! IMPORTANT: I'm not familiar with Irrlicht engine so I append the elements one by one. !!!
   // Check out the Irrlicht documentation and you will probably find a better way
