This function calculates the day number of the quarter in which a timestamp falls.
Syntax:
DayNumberOfQuarter(timestamp[,start_month])
Return data type: integer
The function always uses years based on 366 days.
Arguments:
| Argument | Description |
|---|---|
| timestamp | The date to evaluate. |
| start_month | By specifying a start_month between 2 and 12 (1, if omitted), the beginning of the year may be moved forward to the first day of any month. For example, if you want to work with a fiscal year starting March 1, specify start_month = 3. |
Examples and results:
These examples use the date format DD/MM/YYYY. The date format is specified in the SET DateFormat statement at the top of your load script. Change the format in the examples to suit your requirements.
Example 1:
DayNumberOfQuarter('12/09/2014')
Returns 74, the day number of the current quarter.
Example 2:
DayNumberOfQuarter('12/09/2014',3)
Returns 12, the day number of the current quarter.
In this case, the first quarter starts with March (because start_month is specified as 3). This means that the current quarter is the third quarter, which started on September 1.
Example 3:
Add the example script to your document and run it. Then add, at least, the fields listed in the results column to a sheet in your document to see the result.
