I have a tables:

```
table_1
id   time
1    2012-03-05 12:50:00
2    2012-03-05 12:51:00
3    2012-03-05 12:52:00
4    2012-03-05 12:53:00

table_2
userid   level
100      1
256      2
112      3
400      2
15       1

```

First request: 

```
$sql = 'SELECT `id`, `time` FROM table_1 WHERE `time` > NOW() ORDER BY `id` DESC LIMIT 1';

```

Second request:

```
$sql = 'SELECT COUNT(*) FROM table_2 WHERE `userid` = 100 LIMIT 1';

```

How to combine these two requests into one request?

For example this table:

```
id   time                count
1    2012-03-05 12:53:00 1

```

Or 

```
id   time                count
1    2012-03-05 12:53:00 0

```

If we have no any records in table\_2 
Thanks!
