Alrighty then....I have a table that contains a number of columns.

I want to count the number of instances of each distinct entry in one column.

i.e.

Table has a request_status column - which can have one of 5 states.... approved, rejected, processed ....

I want to count the number of approved and the number of rejected etc. I don't want to do this manually as with 5 it's okay - but I want the syntax for other queries where there are hundreds of states .....
