How do you ensure accuracy when working with sensitive financial or liability data?
Write a SQL query using the policies, liability_transactions, and ledger_entries tables to identify policies with missing data, null financial amounts, or differences between posted liability and ledger totals. Treat differences of 0.01 or less as accurate.
Output
- One row per policy requiring review.
- Return
policy_id, liability_total, ledger_total, variance, and review_status.
- Order by the absolute variance descending, then
policy_id ascending.
Output details
- Consider only records with
transaction_status or entry_status equal to posted.
- Treat a policy lacking posted records on either side as
Missing financial data.
- Treat missing totals as
0.00 when calculating totals and variance.
- Round
variance to two decimal places.
- Classify missing data before
Null financial amount, and classify null amounts before Amount mismatch.
