Hi, may i know how to combine multiple rows value into one? Below are my codes:

SQL

DECLARE @SQL NVARCHAR(MAX)
DECLARE @params NVARCHAR(MAX)

SELECT @SQL = 'SELECT [0] as Pending, [1] as Save_As_Draft, [2] as Spec_Confirmed, [3] as Request_Revision, [4] as Withdraw, [5] as Pending_RND, [6] as Pending_QC, [7] as Manday_Confirmed, [0]+[1]+[2]+[3]+[4]+[5]+[6]+[7] as Total
FROM
(
    SELECT P.DocStatus,P.CustomerID,YEAR(createdate) as specYear
    FROM dbo.CRF_Project P
    INNER JOIN dbo.CustomerList C
    ON P.CustomerID = C.CustomerID
) p

PIVOT
(
    COUNT (CustomerID) FOR DocStatus IN ([0], [1], [2], [3], [4], [5], [6], [7])

) AS pvt '


SELECT @params = '@YEAR VARCHAR(MAX)'

IF(@YEAR != ' ')
    SELECT @SQL = @SQL + ' WHERE specYear = ' + @YEAR +''

SELECT @SQL = @SQL

EXEC sp_executesql @SQL, @params, @YEAR
END

the output i get now for example is:
Pending
=======
15
4

what i want is add up the 15 and 4 into 19

SQL

SELECT @SQL = 'SELECT [0] as Pending, [1] as Save_As_Draft, [2] as Spec_Confirmed, [3] as Request_Revision, [4] as Withdraw, [5] as Pending_RND, [6] as Pending_QC, [7] as Manday_Confirmed, [0]+[1]+[2]+[3]+[4]+[5]+[6]+[7] as Total
FROM
(
    SELECT P.DocStatus, YEAR(createdate) as specYear
    FROM dbo.CRF_Project P
    INNER JOIN dbo.CustomerList C
    ON P.CustomerID = C.CustomerID
) p

PIVOT
(
    COUNT (DocStatus) FOR DocStatus IN ([0], [1], [2], [3], [4], [5], [6], [7])

) AS pvt '


IF(@YEAR != ' ')
    SELECT @SQL = @SQL + ' WHERE specYear = ' + @YEAR +''

ELSE
    SELECT @SQL = 'SELECT [0] as Pending, [1] as Save_As_Draft, [2] as Spec_Confirmed, [3] as Request_Revision, [4] as Withdraw, [5] as Pending_RND, [6] as Pending_QC, [7] as Manday_Confirmed, [0]+[1]+[2]+[3]+[4]+[5]+[6]+[7] as Total
    FROM
    (
        SELECT P.DocStatus
        FROM dbo.CRF_Project P
        INNER JOIN dbo.CustomerList C
        ON P.CustomerID = C.CustomerID
    ) p

    PIVOT
    (
        COUNT (DocStatus) FOR DocStatus IN ([0], [1], [2], [3], [4], [5], [6], [7])

    ) AS pvt '

SELECT @params = '@YEAR VARCHAR(MAX)'
SELECT @SQL = @SQL

EXEC sp_executesql @SQL, @params, @YEAR
END

split the 2 conditions into 2 sql statement, one with where clause and one without where clause. And also the 'SELECT' in subquery.
