Question

I want to extract two types of data which is store in the same column of my table and display it in two column. I have do many search and do many test but nothing works.
It could be easy to do…

This is my table:

| id  | field_id | user_id | value            | 
| 175 |       65 |       3 | 48.8984188201264 | 
| 173 |       65 |       2 | 37.9841493       | 
| 177 |       65 |       4 | 48.8440603       | 
| 179 |       65 |       5 | 48.8407529       | 
| 174 |       66 |       2 | 23.7279843       | 
| 176 |       66 |       3 | 2.25568230749569 | 
| 178 |       66 |       4 | 2.3730525        | 
| 180 |       66 |       5 | 2.3213214        | 

I want to display latitude (Field_id=65) in one field and longitude (field_id= 66) in another one by joining on the user_id.

Two select:

select value as longitude 
from wp_bp_xprofile_data 
where field_id=66; 

select value as latitude 
from wp_bp_xprofile_data 
where field_id=65;

| longitude        |
| 23.7279843       |
| 2.25568230749569 |
| 2.3730525        |
| 2.3213214        |

| latitude         |
| 48.8984188201264 |
| 37.9841493       |
| 48.8440603       |
| 48.8407529       |

How I can display this data in one table with two column?

Thanks

Bassam’s answer is all well and good, but it’s not exactly the most efficient thing in the world. You can simplify your query like so:

select
    t1.user_id,
    t1.value as latitude,
    t2.value as longitude
from
    wp_bp_xprofile_data t1
    inner join wp_bp_xprofile_data t2 on
        t1.user_id = t2.user_id
where
    t1.field_id = 65
    and t2.field_id = 66

This way, you’re not pulling in subqueries, and your query is a little clearer, at least to me.
