Question

表是

Id      name      department        salary
1       ABC       sales             20000
2       DEF       market            30000
3       POL       sales             35000      
4       SWE       market            26000
5       DTR       advert            10000
6       AWK       advert            10000

如果我将销售部门，市场部门或广告部门的薪水相加，并且每个部门的总和都大于50000，则应在输出中显示该值，就像我将薪水是销售部门的20000+ 35000 = 55000大于50000，则应在输出中显示行

这是一个可能的解决方案（包括创建表）。

-- Create table and add data.
IF OBJECT_ID('tempdb.dbo.#_data') IS NOT NULL DROP TABLE #_data
CREATE TABLE #_data (
    [ID] INT IDENTITY(1,1) NOT NULL PRIMARY KEY,
    [name] NCHAR(5),
    [department] NVARCHAR(25),
    [salary] FLOAT
)
INSERT INTO #_data ([name], [department], [salary])
VALUES ('ABC', 'sales', 20000),('DEF', 'market', 30000),('POL', 'sales', 35000),('SWE', 'market', 26000),('DTR', 'advert', 10000),('AWK', 'advert', 10000)



/***
    We'll use a subquery to get the total salary from each department then add in a WHERE clause
    to return only those records above our minimum salary threshold.
    If no minimu salary is given, the default is zero.
*/

------------------------------------------------------------------------------------------------
-- Example with minimum salary value
DECLARE @_min_salary NVARCHAR(10) = 50000

/***
    We first check to see if a value is given
*/
IF @_min_salary IS NULL
    /***
        If no value is given, then we set the minimum salary to zero and get results.
        NOTE: You can also abort the query or have it print a message indicating that
        a salary is required beofre running the query.
    */
    BEGIN
        /***
            Set a new minimum salary value
        */
        SET @_min_salary = 0
    END

/***
    Use a subquery to get total salaries by department.
    Reformat results for a currency format of your choice.
*/
SELECT X.[DEPARTMENT]
,   '$' + CONVERT(NVARCHAR(25), FORMAT(X.TOT_DEPT_SALARY, '#,#.00')) AS [SALARY]
FROM (
    SELECT department AS [DEPARTMENT]
    , SUM(salary) AS [TOT_DEPT_SALARY]

    FROM #_data
    GROUP BY department
) AS X
WHERE X.[TOT_DEPT_SALARY] > @_min_salary
GROUP BY X.DEPARTMENT, X.TOT_DEPT_SALARY

那么您的输出应该是：

DEPARTMENT  SALARY
market  $56,000.00
sales   $55,000.00
