我在这里寻找一些帮助来编写一个 SELECT 语句，该语句也将为我进行一些数据验证。
这是表格的例子：
| 发票行 ID | 发票号 | 订单项成本（收取美元） | 总发票金额 |
|---|---|---|---|
| 1 | VIK123 | 1000 | 1100 |
| 2 | VIK123 | 100 | 1100 |
| 1 | VIK456 | 2000 | 2200 |
| 2 | VIK456 | 200 | 2200 |
我想要一行代码，用于汇总发票编号 VIK123 的发票行 ID 1 和 2 的行项目成本（收取美元），并将其与总发票金额中的值进行比较。我的想法是，这将是一个案例陈述，其中“真”导致“已验证”，“假”导致“价格差异”。
我想 SELECT 语句看起来像这样......
SELECT col1,
col2,
...
CASE
WHEN SUM([Line Item Cost] WHERE [Invoice No] = [Invoice No]) = MAX([Total Invoice Amount] WHERE
[Invoice No] = [Invoice No]) THEN 'Validated'
ELSE 'Price Discrepancy'
END AS [Validation]
FROM [table]
GROUP BY ...
ORDER BY ...
如果需要，我可以提供一些额外的信息。
[Line Item Cost (Collect USD)] 与代码中的 [Collect USD] 相同，我只是这样引用它，以便更容易理解（希望如此）。
我目前在 [Line Item Cost (Collect USD)] 和 [Total Invoice Amount] 上使用 CAST 函数将它们从 varchar(100) 转换为 decimal(18,5)。
我还使用临时表来保存大部分查询，然后使用辅助 SELECT 语句将临时表连接到另一个引用表。我认为这在第二个 select 语句中处理得更优雅。
这里是额外参考的全部内容：
SET NOCOUNT ON;
DROP TABLE IF EXISTS #temp
SELECT * INTO #temp

如有任何帮助，我们将不胜感激。
请尝试以下解决方案。
SQL
-- DDL and sample data population, start
DECLARE @tbl TABLE (InvoiceLineID INT,InvoiceNo VARCHAR(10), LineItemCost MONEY, TotalInvoiceAmount MONEY);
INSERT @tbl (InvoiceLineID, InvoiceNo, LineItemCost, TotalInvoiceAmount) VALUES
(1, 'VIK123', 1000, 1100),
(2, 'VIK123', 100, 1100),

(2, 'VIK456', 200, 2200);
