I have two SQL tables. The first one structure is simple.

```
ID    Name
----------

```

The second one is simple too.

```
CommentID     Comment    CreatorID
----------------------------------

```

I want to show in my site all the comments that correspond with the "ID of user"

The problem is we have here a lot of ID and two different tables. 

Something like this:

```
$1= $bdd->query("SELECT * FROM comments WHERE id_user=220281");
$2=$1->fetch();

```

**But its impossible because** *id user* **is not on the** *comments* **table.**
