Display the total debit counts, total credit counts, sum of total debits, sum of total credits from an employee's transaction table (a single table) containing the following columns. Transaction_number Transaction_amount Transaction_date Transaction_type --> tells if the amount is a credit or a debit. As the query alone is important, the table is left with specifying just the field's name. Pls help me with this query.
