SQL query error not working - sql

Question

I have written a SQL query but I am getting error as
Incorrect syntax near 'company_name'.
I am using SQL Server 2005.
My query:
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)
UPDATE
I have two working queries:
1st query
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
2nd query:
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)
What I want is in second query, I want to add month and year which i get from first query..
I need to merge that in second query

Answer 1

Try something like this - it will use the three emp_card_no given in the outer WHERE clause, and get their most recent month/year entry:
; 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);
I hope that's what you're looking for ! If not - please share table structure, sample data, expected output etc.
