Question

I Have a table like given below, the table name is tag.

id fileid 
== ======
 1   1
 2   2
 3   2
 4   2
 5   3
 6   3
 7   3

I need to find the number of occurrences of each fileId. So the output need to be something like this:

fileId count
====== =====
  1      1
  2      3
  3      3

Can somebody help me with writing this MySQL query?
