SQL 查询错误无效

Question

我写了一个 SQL 查询，但我收到错误

Incorrect syntax near 'company_name'.

我正在使用 SQL Server 2005。

我的查询：

SELECT TOP 1 
    MONTH(a.dt_of_leave) MONTH,
    YEAR(a.dt_of_leave) YEAR 
FROM 
    emp_mst a 
WHERE 
    MONTH(a.dt_of_leave) >= MONTH(getdate()) - 1
    AND YEAR(a.dt_of_leave) = CASE 
                                 WHEN MONTH(getdate()) = 1  
                                 THEN YEAR(getdate()) - 1 
                                 ELSE YEAR(getdate()) company_name 'COMPANY NAME',
    Deputed_Company_Name 'DEPUTED COMPANY NAME' emp_card_no 'EMP CODE',
    emp_name 'EMPLOYEE NAME',
    LWP,
   '' Remarks,
   Adj_Days Gain_Loss_LOP_Days,
   VAL_DAY LOP_Days_Desc,
   MONTH,
   YEAR
 FROM XXACL_EMP_INFO_LWP_OTDAYS_HRS_V WHERE emp_type='C'
  AND MONTH = '3'
 AND YEAR = '2016'
 AND emp_card_no IN(312,
                 1250,
                 362)

更新

我有两个工作查询：

第一次查询

select top 1 
    month(a.dt_of_leave) month,  
    year(a.dt_of_leave) year
from 
    emp_mst a 
where 
    month(a.dt_of_leave) >= month(getdate())-1  
    and year(a.dt_of_leave) = case 
                                 when month(getdate()) = 1 
                                    then year(getdate()) - 1 
                                    else year(getdate()) 
                              end
    and emp_card_no IN (312, 1250, 362)
order by 
    emp_name

第二次查询：

select 
    company_name 'COMPANY NAME',
    Deputed_Company_Name 'DEPUTED COMPANY NAME', 
    emp_card_no 'EMP CODE',
    emp_name 'EMPLOYEE NAME',
    LWP, '' Remarks, 
    Adj_Days Gain_Loss_LOP_Days, 
    VAL_DAY LOP_Days_Desc, month, year 
from 
    XXACL_EMP_INFO_LWP_OTDAYS_HRS_V 
where 
    emp_type = 'C' 
    and month = '3' and year = '2015' 
    and emp_card_no in (312, 1250, 362)

我想要的是在第二个查询中，我想添加从第一个查询中获得的月份和年份..

我需要在第二个查询中合并它

尝试这样的事情 - 它将使用外部 WHERE 子句中给出的三个 emp_card_no，并获取它们最近的 month/year 条目：

; WITH MonthAndYear AS 
(
    SELECT 
        MONTH(a.dt_of_leave) month, 
        YEAR(a.dt_of_leave) year,
        emp_card_no,
        RowNum = ROW_NUMBER() OVER (PARTITION BY emp_card_no ORDER BY dt_of_leave DESC)
    FROM
        emp_mst a
    WHERE
        MONTH(a.dt_of_leave) >= MONTH(GETDATE()) - 1
        AND YEAR(a.dt_of_leave) = CASE 
                                     WHEN MONTH(GETDATE()) = 1 
                                        THEN YEAR(GETDATE()) - 1
                                        ELSE YEAR(GETDATE())
                                     END
)
SELECT
    x.company_name 'COMPANY NAME', 
    x.Deputed_Company_Name 'DEPUTED COMPANY NAME', 
    x.emp_card_no 'EMP CODE', 
    x.emp_name 'EMPLOYEE NAME', 
    x.LWP, '' Remarks,
    x.Adj_Days Gain_Loss_LOP_Days, 
    x.VAL_DAY LOP_Days_Desc, 
    x.month, x.year
FROM
    XXACL_EMP_INFO_LWP_OTDAYS_HRS_V x
INNER JOIN 
    MonthAndYear my ON x.emp_card_no = my.emp_card_no 
                    AND x.Month = my.Month AND x.Year = my.Year
                    AND my.RowNum = 1
WHERE
    x.emp_type = 'C'
    AND x.emp_card_no IN (312, 1250, 362);

我希望这就是您要找的！如果没有 - 请分享 table 结构 、示例数据、预期输出等
