I have two tables Employee Details and EmpAttendance.

Employee Details has EmployeeID ,EmployeeNAME, EMailID columns.
EmpAttendance has c_Date , Eid, Intime, Outtime,Count columns.

i have a form in windows app, when we type employeeID and press Submit Button, I need to display

S.NO c_Date EmployeeID EmployeeNAME EMailID Intime Outime Count TotalWorkingHours

where TotalWorkingHours is the difference between outtime and intime.

suggest me how to do this.

You need to start with database basics.
Do a join between the two tables and subrtact the datetimes values for intime and outtime to get totalworking hours.

Simple Database Application - Part 1[^] should help you get started.

For datetime calculations on query, try[^].

There is no Foreign Key in EmpAttendance or Matching values, so no join is possible.

Do we need a foreign key actually defined in order to do a join ?

Not necessary but a matching column values with same datatype should be there for Join condition.
Make a Foreign Key in Table EmpAttendance with respect to EmployeeID; then do Join with matching this columns.
