my appdelegate code for insert value from one table to other is given bellow

      -(void)sopinglist

         {

      //////databaseName= @"SanjeevKapoor.sqlite";

           databaseName =@"AjeetTest.sqlite";

     NSArray *documentPaths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory,        NSUserDomainMask, YES);
       NSString *documentsDir = [documentPaths objectAtIndex:0];
      databasePath =[documentsDir stringByAppendingPathComponent:databaseName];

          [self checkAndCreateDatabase];

        list1 = [[NSMutableArray alloc] init];  

            sqlite3 *database;
          if (sqlite3_open([databasePath UTF8String], &database) == SQLITE_OK)
           {

              if(addStmt == nil) {
            ///////////const char *sql = "insert into Dataa(item) Values(?)";

            const char *sql = " insert into Slist select * from alootikki";

             /////////////  const char *sql =" Update Slist ( Incredients,        Recipename,foodtype) Values(?,?,?)";
               if(sqlite3_prepare_v2(database, sql, -1, &addStmt, NULL) !=  SQLITE_OK)
              NSAssert1(0, @"Error while creating add statement. '%s'",    sqlite3_errmsg(database));
         }



       /////for( NSString * j in k)


            sqlite3_bind_text(addStmt, 1, [k UTF8String], -1, SQLITE_TRANSIENT);


            //sqlite3_bind_int(addStmt,1,i);    //  sqlite3_bind_text(addStmt,       1, [coffeeName UTF8String], -1, SQLITE_TRANSIENT);
              //    sqlite3_bind_double(addStmt, 2, [price doubleValue]);

                 if(SQLITE_DONE != sqlite3_step(addStmt))
               NSAssert1(0, @"Error while inserting data. '%s'", sqlite3_errmsg(database));
            else
               //SQLite provides a method to get the last primary key inserted by using sqlite3_last_insert_rowid
                 coffeeID = sqlite3_last_insert_rowid(database);

                 //Reset the add statement.
              sqlite3_reset(addStmt);       

           //   sqlite3_clear_bindings(detailStmt);
            //}
      }
         sqlite3_finalize(addStmt); 
         addStmt = nil;

       sqlite3_close(database);
        }

And the table View code for access data from database is given bellow

       SanjeevKapoorAppDelegate *appDelegate =(SanjeevKapoorAppDelegate *)[[UIApplication sharedApplication] delegate];



        [appDelegate sopinglist];


       ////[appDelegate recpies];

       /// NSArray *a =[[appDelegate list1] componentsJoinedByString:@","];
       k= [[appDelegate list1] componentsJoinedByString:@","];
