MySQL Query multiple tables with data to columns

Question

I need to pull data from three tables and have the result returned in a single row for each user. I also need to use variable column names based on the value of a field.

My query is:

SELECT u.USER_ID, u.FIRST_NAME, d.FIELD_ID, d.DATA, f.LABEL, f.TYPE
    FROM users as u, fields as f, fieldsData as d
    WHERE d.USER_ID=u.USER_ID AND f.FIELD_ID=f.FIELD_ID;

The result I get is:

|------------|-------------|----------|-----------|---------|----------|
| USER_ID    | FIRST_NAME  | FIELD_ID | DATA      |LABEL    | TYPE     |
|------------|-------------|----------|-----------|---------|----------|
| 1          | John        | 1        | Cookies   | Dessert | TEXT     |
| 1          | John        | 2        | Chocolate | Flavor  | TEXT     |
| 1          | John        | 3        | Milky Way | Candy   | TEXT     |
| 2          | Sally       | 1        | Brownies  | Dessert | TEXT     |
| 2          | Sally       | 3        | Snickers  | Candy   | TEXT     |
|------------|-------------|----------|-----------|---------|----------|

What I need is only one row per user with columns for the fields / field data values. Something like this:

|------------|-------------|--------------|----------|---------------|---------------|------------|
| FIRST_NAME | Dessert     | Dessert_TYPE | Flavor   | Flavor_TYPE   | Candy         |Candy_TYPE  |
|------------|-------------|--------------|----------|---------------|---------------|------------|
| John       | Cookies     | TEXT         | Chocolate| TEXT          | Milky Way     | TEXT       |
| Sally      | Brownies    | TEXT         | NULL     | NULL          | Snickers      | TEXT       |
|------------|-------------|--------------|----------|---------------|----------------|------------|

You must to do a INNER JOIN:

SELECT u.USER_ID, u.FIRST_NAME, d.FIELD_ID, d.DATA, f.LABEL, f.TYPE
    FROM fieldsData as d 
    INNER JOIN users as u ON d.USER_ID = u.USER_ID
    INNER JOIN fields as f ON d.FIELD_ID = f.FIELD_ID;

I hope It can be useful!
