Subject Re: [IBO] Calculating data
Hi Marcin, I need help coding the trigger.
I have a relational database with 2 tables. The primary and the secondary as shown. If you add up the hours worked in the secondary table for Smith  it is 24  so hours in the primary table = 24

Primary Table
id       surname    hours
100     smith        24

Secondary Table
id           Work           Hours
100    McDonalds       10
200    BMW                  6
100    Google                8
100    Microsoft             6
300    Oracle                 5

Any help would be appreciated.
