##Evidence:
Weekly statement issuance refers to frequency = 'POPLATEK TYDNE'; high-volume clients are those with total transaction amount > 10000

##Role Access Policy (Column-Level):
Role: DataOperator_1
Accessible Columns: account: date, district_id, frequency; card: ALL COLUMNS; disp: ALL COLUMNS; district: A10, A13, A14, A16, A2, A5, A6, A7, A9, district_id; loan: account_id, date, loan_id, status; order: account_id, account_to, amount, bank_to, k_symbol; 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: What are the key statistics for account owners with weekly statement issuance, including how many owners there are, their average number of transactions, how many have credit cards, how many are high-volume clients with over 10,000 in total transactions, the number of districts they're located in, and their average account balance?
Evidence: Weekly statement issuance refers to frequency = 'POPLATEK TYDNE'; high-volume clients are those with total transaction amount > 10000
Answer: Sorry, I cannot answer.
