How to group field data?

Question

I have sql query to show data

\"SELECT
  `artikel`.`foto_naam`,
  `fotografer`.`id`,
  `fotografer`.`name_fotografer`,
  `customer`.`first_name`,
  `customer`.`l         


        

Answer 1

One thing you can do in mysql is to wrap you query with a group by and group_concat(). Something like this:

SELECT
    name, 
    email, 
    group_concat(customer) AS customers, 
    group_concat(invoice_id) AS invoice_ids
FROM
    (...query you already have..)
GROUP BY
    name, email

Result will look like something like this:

name    email               customers           invoice_ids

heko    heko@gmail.com      pae,edwin           15,16
Lekto   lekto@gmail.com     edwin,risa,edwin    11,12,13

Answer 2

Odd question, but if you REALLY NEED THIS in MySQL then you could use USER VARIABLES to set the Name and email column to '' (empty string) for subitems in the list.

DEMO FIDDLE or e.g.

select 
    if(@tName!= Name, if(@'tNAME':= Name, Name,Name) , '' ),
    if(@tEmail!= Email, if(@'tEmail':= Email, Email ,Email) , '' ),
    customer,
    invoice_id,
    /* blah blah blah */
from 
    tables
    join (select @'tName':='', @'tEmail':='') T on 1=1 
/* blah blah blah */

I provide the join (select @'tName':='') T on 1=1 to re-initialize the user variable just in case you can't control them.
