Question

Hi i have this sql code i want to query in phpmyadmin

SELECT DISTINCT `unit`,`location` FROM `myasset` ORDER BY `unit` asc                  

It is possible to add custom number in my sql result

I tried something like below..its not working ..i received message row_number function does not exist

  SELECT DISTINCT Row_Number(),`unit`,`location` FROM `myasset` ORDER BY `unit` 



 SELECT Row_Number() DISTINCT`unit`,`location` FROM `myasset` ORDER BY `unit` 

Answer 1

你可以做

select @rownum:=@rownum+1 No,DISTINCT unit,location FROM myasset ORDER BY unit, (SELECT @rownum:=0);

Answer 2

First you have to set a value like

SET @rnum = 0;

then

SELECT @rnum:=@rnum+1 AS row_num, DISTINCT unit , location FROM myasset ORDER BY unit asc

Hope it will solve your issue.

Thanks
