""" tenant = json.loads(get_current_tenant())["data"][0][0] if tenant != "sys": raise ValueError("Only sys tenant can get all server nodes") logger.info("Calling tool: get_all_server_nodes") sql_query = "select * from oceanbase.DBA_OB_SERVERS" try: return execute_sql(sql_query) except Error as e: logger.error(f"Error executing SQL '{sql_query}': {e}") return f"Error executing query: {str(e)}"
