Question

I am trying fetch the value from data base But it is not getting
I am trying this code but didn’t get the value ,When i use the Break point on the program
I am having Longitude,Latitude his data type is double in data base

if(sqlite3_open([dbPath UTF8String], &database) == SQLITE_OK) 
    {
        NSString *sqlStr = [NSString stringWithFormat:@"select Longitude,Latitude from Location"];
        const char *sqlStatement = [sqlStr UTF8String];
        sqlite3_stmt *compiledStatement;

        if(sqlite3_prepare_v2(database, sqlStatement, -1, &compiledStatement, NULL) == SQLITE_OK) {
            locations = [NSMutableArray array];

            while(sqlite3_step(compiledStatement) == SQLITE_ROW) {
                int i = sqlite3_step(compiledStatement);
                NSLog(@"%i",i); **//over here i am getting the 101 value in console** And my pointer getting out from here 
                NSString *dLongitude = [NSString stringWithUTF8String:(char *)sqlite3_column_text(compiledStatement, 3)];
                NSString *dLatitude = [NSString stringWithUTF8String:(char *)sqlite3_column_text(compiledStatement, 4)];    
                [locations addObject:[NSString stringWithFormat:@"%@ ,%@",dLongitude,dLatitude]];
                NSLog(@"%@",locations);
            }

            result = [locations componentsJoinedByString:@" "]; // same as `fake_location`

            // Get file path here

            NSError *error;
            if ( [result writeToFile:dbPath atomically:YES encoding:NSUTF8StringEncoding error:&error] ) {
                NSLog(@"%@", [error localizedDescription]);
            }
        }
        // Release the compiled statement from memory
        sqlite3_finalize(compiledStatement);

    while(sqlite3_step(compiledStatement) == SQLITE_ROW) {
                    int i = sqlite3_step(compiledStatement);
                    NSLog(@"%i",i); **//over here i am getting the 101 value in console** And my pointer getting out from here 

                    double longitude = sqlite3_column_double(compiledStatement, 3);
                    double latitude = sqlite3_column_double(compiledStatement, 4);

                    NSString *coords = [[[NSString alloc] initWithFormat:@"%f,%f",longitude,latitude] autorelease];

                    [locations addObject:coords];
                    NSLog(@"%@",locations);
                }
