Question

So I’ve asked a question like this before, and I guess I just didn’t understand the answer (although the answer worked) to input the answer into this next problem

Easy query. I’m pulling employee, date, totalhrs. out of a timecard program PER employee. What i’m looking for is a sum of totalhrs colum but also to display ALL the timecard’s submitted. So the code I use now

 SELECT date,totalhrs,SUM(totalhrs) 
 FROM tcardsubmit 
 WHERE employee= 'employee name' 
 ORDER BY date

This code displays

|EMPLOYEE | DATE        | TOTALHRS | SUM(TOTALHRS)
| myname  | myfirstdate |     5    |     10

What I want it to display is ALL the timecards that a specific employee has entered. Not JUST the one link. So in ‘myname’ I would have 3 timecards where the SUM does in fact equal 10 hours submitted for the week. The sum works for the math. I just can’t seem to get it to display all the timecards that employee has entered. Here is what I want it to look like

|EMPLOYEE | DATE         | TOTALHRS | SUM(TOTALHRS)
| myname  | myfirstdate  |     5    |     10
| myname  | myseconddate |     4    |     10
| myname  | mythirddate  |     1    |     10

Test this and see if this works for you:

SELECT 
    date, 
    totalhrs, 
    (SELECT SUM(b.totalhrs) FROM tcardsubmit b WHERE b.employee = a.employee) AS totalhrs_sum 
FROM 
    tcardsubmit a 
WHERE 
    employee = 'employee name' 
ORDER BY 
    date 

Explanation For where clause in sub select:
In the sub select WHERE clause, we are checking to get just the records that have same employee as the main select employee (b.employee = a.employee) so the SUM(b.totalhrs) would be only sum of records for the employee you are getting his records. In main select we say FROM tcardsubmit a so we name the main tcardsubmit a and in the sub select we name the table b to avoid any conflicts because of using same table and field names.
