mysql - SQL ID not in the table -


so i'm looking solution check if "id" in sql.

select id t_data partnerid=12

the id logged in user. 

<?php echo $id ?>

so works fine if there entries right id in table. if there no row id error. possible set if id not in row nothing?

use following:

  select ifnull(id,'') t_data partnerid=12

or can use

select if(id not null, id ,'')  t_data partnerid=12
