I have the following data set:
| Worker | Hours | 
|---|---|
| Johnny | 8 | 
| Johnny | 7 | 
| Johnny | 4 | 
| Liz | 7 | 
| Liz | 2 | 
| Sally | 9 | 
| Sally | 9 | 
| Sally | 3 | 
I need a SQL Select statement to sum the results for each distinct person. Ideally my results would look like the following:
| Worker | Hours | 
|---|---|
| Johnny | 19 | 
| Liz | 9 | 
| Sally | 21 | 
I'm able to do this in SQL by looping through the data set, but for this problem I'm constrained to a single SELECT statement. Thanks in advance.
