Question

I have records as follows:

key  | name
--------------
1111 | aa   
1111 | bb    
2222 | cc

I need to select the key and name when the key value is distinct. When I tried:

select distinct key, name from table;

I got all the rows since the query takes distinct for the combination of the columns: key and name. But, what I need is only distinct key and I don’t care about the name. I have a lot of records, so I need a practical method.

Query:

SELECT `key`, MAX(`name`) as name
FROM `table`
GROUP BY `key`
