Question

Example

I want to calculate the worktime between 09:00:00 to 18:00:00,

09:00:00 - Normal_Intime
18:00:00 - Normal_Outtime

Suppose

1) Intime is 10:00:00, Outtime is 17:00:00 It should give the output as 07:00:00
2) Intime is 08:00:00. Outtime is 19:00:00 It should give the output as 09:00:00

above output should compare with Normal_Intime, Normal_Outtime .

Means Normal_Intime is 09:00:00 only and Normal_Output is 18:00:00 only, so Intime should not > 09:00:00 and Outtime < 18:00:00.

Query

select Intime, Outtime, CONVERT(char(8), CASE WHEN OutTime > Normal_Outtime THEN cast(Normal_Outtime AS datetime) ELSE cast(OutTime AS datetime) END - CASE WHEN InTime > Normal_Intime THEN cast(InTime AS datetime) ELSE cast(Normal_Intime AS datetime) END, 8) AS WorkTime from table

Output

Intime       Outtime        Worktime
15:37:48    22:08:15    02:22:12
07:33:34    07:59:13    22:59:13

the Second Row giving wrong output It should give only 00:25:39

If both in and out time is smaller than NormalInTime and both in and out time is greater than NormalOutTime. How to make a condtion for this

This should get you what you want

DECLARE @Table TABLE(
        InTime DATETIME,
        OutTime DATETIME
)

INSERT INTO @Table (InTime,OutTime) SELECT '15:37:48', '22:08:15'
INSERT INTO @Table (InTime,OutTime) SELECT '07:33:34', '07:59:13'

DECLARE @Normal_InTime DATETIME,
        @Normal_OutTime DATETIME

SELECT  @Normal_InTime = '09:00:00',
        @Normal_OutTime = '18:00:00'

SELECT  *,
        --both dates are smaller than NotmalInTime
        CASE
            WHEN InTime < @Normal_InTime AND OutTime < @Normal_InTime THEN OutTime - InTime
            WHEN OutTime > @Normal_OutTime AND InTime > @Normal_OutTime THEN OutTime - InTime
            WHEN OutTime > @Normal_OutTime 
                THEN @Normal_OutTime - InTime
            WHEN InTime < @Normal_InTime
                THEN OutTime - @Normal_InTime
            ELSE OutTime - InTime
        END
FROM    @Table

But you need to take into account. What happens when the user books in before 24:00 and then books out the next day.

And as i said, what happens in the event that book in and bookout is either before NormalTimeIn or after NormalTimeOut?

you need to specify this.
