_databasePath = [[NSString alloc] initWithString: [docsDir stringByAppendingPathComponent:@"Personal.db"]];
NSLog(@"DataBase PAth %@",_databasePath);
NSFileManager *filemgr = [NSFileManager defaultManager];

if ([filemgr fileExistsAtPath: _databasePath ] == YES)
{
    const char *dbpath = [_databasePath UTF8String];
    if (sqlite3_open(dbpath, &_myDatabase) == SQLITE_OK)
    {
        char *errMsg;
        const char *sql_stmt =
        "CREATE TABLE IF NOT EXISTS QpinPersonal (ID INTEGER PRIMARY KEY AUTOINCREMENT, UserName TEXT, QpinName TEXT, Address TEXT, Lat DOUBLE, Long DOUBLE,Type TEXT)";
        if (sqlite3_exec(_myDatabase, sql_stmt, NULL, NULL, &errMsg) != SQLITE_OK)
        {
        NSLog(@"Failed TO Create Table");
        }
