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

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.
