Sql server 如何检查以下cte中是否没有应付款项

CTE的工作令人敬畏，但我不知道在哪里把条件，如果销售是第一 我希望在这种情况下，如果每个accountid的借方数超过1，sum函数可以工作

CREATE PROCEDURE [dbo].[counter_bills] @SDate date,
                                       @enddate date
AS
BEGIN;

    WITH
    CUST AS
        (SELECT customer.customername,
                customer.customercontact,
                customer.customeraddress,
                account.account_id,
                account.account_type,
                customer.customerid
         FROM account
              JOIN customer ON customer.customerid = account.customerid),
    journal AS
        (SELECT SUM(journal_entry.debit) - SUM(journal_entry.credit) AS [dues],
                journal_entry.account_id AS [journal account id]
         FROM journal_entry
         GROUP BY journal_entry.account_id),
    SALES AS
        (SELECT sale.saleid,
                sale.totalpaid,
                Stock.itemname AS item,
                invoice.saleprice AS SalePrice,
                invoice.qty,
                invoice.StockID AS [invoice Stock id],
                invoice.saleprice AS [invoice saleprice],
                sale.date,
                Stock.size,
                sale.customerid AS [cust sale id ]
         FROM invoice
              JOIN Stock ON invoice.StockID = Stock.StockID
              JOIN sale ON invoice.saleid = sale.saleid
              JOIN Our_orders ON Stock.orderID = Our_orders.orderID
              JOIN vendor ON Our_orders.VendorID = vendor.VendorID
         WHERE sale.date BETWEEN @SDate AND @enddate)
    SELECT *
    FROM CUST
         RIGHT JOIN SALES ON CUST.customerid = SALES.[cust sale id ]
         LEFT JOIN journal ON journal.[journal account id] = CUST.account_id
    ORDER BY SALES.SaleID DESC;
END;

如果

不是t-SQL中的表达式，则它是一个逻辑运算符：如果这些条件为真，则执行这些操作，否则执行这些操作。在语句的中间，如果你不能把<代码>放在，那么我不确定你想解决什么问题。换句话说，好地使用别名、空白和断线会使你的查询更容易阅读。这些东西很乱，很难理解。（我已经做了一些格式化，但我建议您开始使用别名。）此外，在持久化对象中使用

*

也是一个坏主意<代码>*不是一个神奇的“所有列”操作符，它的行为会根据对象类型而变化，当底层对象发生变化时，可能会导致意外行为。
