what kind of output you want, in seconds or in time or any other format?

V Mohan 7-May-14 1:22am

I want two outputs one is sum of all integer values as integer and another one is sum of all time in time format.

Thanks

do you have any other column that will identify your column value is interger or Time.

Otherwise in where condition check for int or time

I tried, But it shows error. Please help me to get sum of all int and sum of all time value in a query

Thanks for your reply. I tried but it shows error as below

Operand data type nvarchar is invalid for sum operator.

Why are you storing Integer and time in Same column? or What is that?

Solution 3

Another solution is:

SQL

DECLARE @tmp TABLE (ID INT IDENTITY(1,1), Value VARCHAR(10))

INSERT INTO @tmp (Value)
VALUES('10'),('20'),('30'),('9:15'),('10:15'),
        ('8:10'),('9:15'),('40'),('50')


SELECT DATEADD(ms, SUM(DATEDIFF(ms, '00:00:00.000', T1.TValue )), '00:00:00.000') AS SumOfTime
FROM (
    SELECT ID, Value AS TValue
    FROM @tmp
    WHERE CHARINDEX(':', Value)>0
    ) AS T1


SELECT SUM(CONVERT(INT,T2.IValue)) AS SumOfInt
FROM (
    SELECT ID, Value AS IValue
    FROM @tmp
    WHERE CHARINDEX(':', Value)=0
    ) AS T2

Results:

SumOfTime
1900-01-02 12:55:00.000  - it means 2 days and 12 hrs 55 mins

SumOfInt
150

Solution 1

you can do it like this

this will give you sum of all integers

SQL

SELECT Sum(value)
    FROM YourTable
    WHERE ISNUMERIC(value + '.0e0') = 1

this will give you sum of all time

SELECT Sum(convert(time,value))
    FROM YourTable
     WHERE ISNUMERIC(value + '.0e0') != 1

I'm sure you'll get error message: Msg 8117, Operand data type time is invalid for sum operator. for the second query.

Darshan.Pa 7-May-14 2:01am

try now answer is updated

V Mohan 7-May-14 2:11am

Because the Data type for Value is nvarchar. So its shows error as below

Operand data type time is invalid for sum operator.

Solution 2

Try this

to add integer value :

SQL

select sum(cast(value as float))From ##table where not value like '%:%'

To add Time value

SQL

select convert(time,dateadd(s,SUM(
( DATEPART(hh, value) * 3600 ) +
( DATEPART(mi, value) * 60 ) +
 DATEPART(ss, value)),0)) From ##table where value like '%:%'

Thanks for yor reply. Second query is working fine. But the first query is showing error as follows

Conversion failed when converting the nvarchar value '4.3' to data type int.

Maciej Los 7-May-14 2:22am

First query uses NOT LIKE. Did you wrote it properly?

V Mohan 7-May-14 2:19am

Because value is nvarchar type

King Fisher 7-May-14 2:23am

make it as float
