MySQL Select rows on first occurrence of each unique value

Question

Let\'s say you have the following table (the column of interest here is cid):

+-----+-------+-------+-------+---------------------+-------------         


        

Answer 1

I know it's an old thread, the accepted solution would only retrieve me the columns that had more than one occurrence.

This worked for me:

SELECT cid, pid, rid, clink, MAX(time), snippet 
FROM mytable 
GROUP BY cid
