164Dear Brainstrust,
I am building a timesheet application to capture timesheet hours and would like to ensure that users can only enter times which are free ie have no times already used.
I have a SQL table with timesheet transactions
dbo.timesheet.transactions
Id
Start_Time
Finish_Time
Employee_Id
Date
Activity_Type
I also have a time table with allowable times
dbo.timesheet.times
Id
Time
Free
Where time is in 15min increments
To restrict the user from entering times which already exist I've created a collection based on the dbo.timesheet.table which I want to use to check whether a new record's time is free and update when a new timesheet record is created. The check and update needs to work for a range of times between Start_Time and Finish_Time for each record. Collection name ColTimes
I'm stuck on how to update the collection with the times used, for example:
2 timesheet records dbo.timesheet.transactions
Record 1
Id 1
Start_Time 8:00
Finish_Time 10:00
Employee_Id 4
Date 11-23-2020
Activity_Type Work
Record 2
Id 2
Start_Time 10:00
Finish_Time 12:30
Employee_Id 4
Date 11-23-2020
Activity_Type Work
The resulting Collection
ColTimes
Id
Time
Free
Would look like this:
| Id | Time | Free |
| 1 | 12:00:00 AM | Yes |
| 2 | 12:15:00 AM | Yes |
| 3 | 12:30:00 AM | Yes |
