How can I get my active account_bugdet only?

[min jia]

Hi, Team

The only account_budget active in my google-ads management UI  backend is as below showed (as attachment gg1024.png showed):

{
        "account_id":xxxxxxxx,
        "account_budget_id":xxxxxxxxxx,
        "account_budget_name":"BlueFocus International Limited - 2018年12月27日",
        "account_budget_status":"APPROVED",
        "approved_start_date_time":20181227,
        "approved_end_date_time":null,
        "approved_end_time_type":"FOREVER",
        "approved_spending_limit_type":"UNSPECIFIED",
        "approved_spending_limit_micros":1000,
        "adjusted_spending_limit_micros":1200,
        "amount_served_micros":12230
    }


But when I want to get all account_budgets under my account , I got results below， I‘m using GASQL

query = """
       SELECT
                 customer.id,
                 account_budget.id,

                 account_budget.status,
                 account_budget.approved_end_date_time,
                 account_budget.approved_start_date_time,
                 account_budget.approved_spending_limit_micros,
                 account_budget.adjusted_spending_limit_micros,
                 account_budget.approved_spending_limit_type,
                 account_budget.approved_end_time_type,
                 account_budget.amount_served_micros,
                 
                 account_budget.pending_proposal.creation_date_time,
                 account_budget.pending_proposal.proposal_type,
                 account_budget.resource_name,
                 account_budget.total_adjustments_micros,

        FROM
            account_budget
            
        
        WHERE account_budget.approved_end_time_type = 'FOREVER'
        AND account_budget.status = 'APPROVED'
        
        ORDER BY
             account_budget.approved_start_date_time DESC
        
        LIMIT
            100
        """
