Talking through your plan before coding is graded well.

Problem

UC Davis Financial Services wants a simple reconciliation view from Aggie Enterprise export data. Write a SQL query to summarize posted financial activity by account for March 2024.

Requirements

  1. Return one row per account_code.
  2. Include only rows where status = 'Posted' and transaction_date is in March 2024.
  3. Calculate:
    • total debit amount
    • total credit amount
    • net activity as SUM(debit_amount) - SUM(credit_amount)
  4. Sort the result by net_activity descending, then account_code ascending.
