SQL & PL/SQL

I have the following two queries that I need to combine into one query, where it updates a single row at the same time.

SELECT count(*) FROM database.USAGE WHERE SERVICE_TYPE = 'C' AND ACCOUNT = "4837"

SELECT sum(minutes) FROM database.USAGE WHERE SERVICE_TYPE = 'DA' AND ACCOUNT = "4837"

I want to insert the values of each select statement into two columns of the same row, as well as insert the account number from the select statement.

After the query has been executed, the database row will look like this:

ACCOUNT COUNT SUM
4837 354 1039202

I am looking for suggestions on how to:

- either combine the two into one query
- simply update each column with the value from each query by updating the row with the account value

I am a SQL newbie - so I appreciate any assistance.

Thanks,

Tony
