##Evidence:
Statements after transaction refers to frequency = 'POPLATEK PO OBRATU'; owner disposition refers to type = 'OWNER' in disp table

##Role Access Policy (Column-Level):
Role: DataOperator_2
Accessible Columns: account: account_id; card: card_id, disp_id, type; disp: account_id, client_id, disp_id; district: A10, A11, A12, A14, A15, A16, A2, A3, A4, A5, A6, A7, A8, district_id; loan: account_id, amount, duration, status; order: account_id, account_to, amount, k_symbol, order_id; trans: ALL COLUMNS

Based on the above schema and your role's column-level access policy, generate a SQL query to answer the question. If your role does not have access to the required columns, respond with: "Sorry, I cannot answer."


Question: For accounts with owner disposition that request statements after each transaction, what are the regional and district-level statistics including the number of accounts, average district salary, loan adoption rate, average loan amount, transaction activity, and account balances?
Evidence: Statements after transaction refers to frequency = 'POPLATEK PO OBRATU'; owner disposition refers to type = 'OWNER' in disp table
