我有一张桌子和一些数据。我想为每个帐户分配级别。
DROP TABLE COA;
CREATE TABLE COA
(
ID NUMERIC NOT NULL PRIMARY KEY,
COACode VARCHAR(50),
COATitle VARCHAR(50),
ParentCode NUMERIC,
DebitAmount NUMERIC(30),
CONSTRAINT FK_COAParentCode
FOREIGN KEY (ID) REFERENCES COA(ID)
);
INSERT INTO COA VALUES (1, '01', 'Expenses', NULL, NULL);
INSERT INTO COA VALUES (2, '02', 'Assets', NULL, NULL);
INSERT INTO COA VALUES (3, '03', 'Bills', NULL, NULL);
INSERT INTO COA VALUES (4, '01-01', 'Salary Expenses', 1, NULL);
INSERT INTO COA VALUES (5, '01-02', 'Staff Transport Expenses', 1, NULL);
INSERT INTO COA VALUES (6, '01-01-01', 'Internship Stippends', 4, NULL);
INSERT INTO COA VALUES (7, '01-01-02', 'Non Technical Staff Pay', 4, '1500');
INSERT INTO COA VALUES (8, '01-01-03', 'Technical Staff Pay', 4, '5000');
INSERT INTO COA VALUES (9, '01-02-01', 'Staff Transport Charges', 5, NULL);
INSERT INTO COA VALUES (10, '01-02-02', 'Daily Product Delivery Transport Charges', 5, '10000');
INSERT INTO COA VALUES (11, '02-01', 'East Plant Dues', 2, NULL);
INSERT INTO COA VALUES (12, '02-02', 'West Plant Dues', 2, NULL);
INSERT INTO COA VALUES (13, '03-01', 'Electricity Bills', 3, NULL);
INSERT INTO COA VALUES (14, '03-01-01', 'Head Office Electricity Bills', 13, '1200');
INSERT INTO COA VALUES (15, '03-01-02', 'Plant Electricity Bills', 13, '1300');
INSERT INTO COA VALUES (16, '03-02', 'Phone Bills', 3, NULL);
INSERT INTO COA VALUES (17, '03-02-01', 'Mobile Phone Charges', 16, '4500');
INSERT INTO COA VALUES (18, '03-02-02', 'Landline Charges', 16, NULL);
INSERT INTO COA VALUES (19, '03-02-03', 'Internet Charges', 16, '2400');
对于资产的费用2和对于账单的3应该是1级。我想分组并显示每个帐户的金额总和。
以下是我正在寻找的格式，我相信如果我按级别进行分组但不确定如何在运行时分配级别，则可以执行此操作。另外我不是在sql窗口中寻找这种格式我正在创建一个报告，如果我相应地对它进行分组，我可以实现这种格式。所以我希望有人能帮我分配账户级别。

这样的事情会起作用吗？
select top 1000
*,
Level1Sum = sum(DebitAmount) over (partition by left(COACode, 2)),
Level2Sum = sum(DebitAmount) over (partition by left(COACode, 5))
from COA
order by COACode
答案 1 :(得分：1)
更新答案：
SELECT
COACode,
COATitle,
ParentCode,
DebitAmount,
Level# AS Level,
sum(debitamount) OVER (PARTITION BY ParentCode) AS Total
FROM (
SELECT *, dense_rank() OVER (PARTITION BY ParentCode ORDER BY COACode) AS Level#
FROM COA
) Tab
ORDER BY COACode
<强>结果：
COACode COATitle ParentCode DebitAmount Level Total
