mysql return unique rows

I have a table columns
name, city, pledgetype(2 choices), and a few others

Is there a way to pick unique where
name and city is the same but pledge is different? ( so i would have each person either show up once or twice)

Even better, would there be a way to put only 1 name and city unique and in the pledge field put all the different pledges from different rows from that person.

Do you mean something like:

select name, city, pledgetype from table_name group by name, city, pledgetype;

Open in new window

Words are just inadequate to describe data arrangements.

a small sample of the raw data, then an "expected result" really help

This MIGHT be what you want.

SELECT
          name
	, city
	, MAX(CASE WHEN pledgetype = 1 THEN pledgetype END) AS pledgetype1
	, MAX(CASE WHEN pledgetype = 2 THEN pledgetype END) AS pledgetype2
FROM your_table
GROUP BY
          name
	, city
;

Hi!

You could do this also with GROUP_CONCAT like this

select name, city, GROUP_CONCAT(pledgetype) as pledgetype 
from table_name 
group by name, city

Open in new window
