This function returns True if timestamp lies inside the day containing base_timestamp.
Syntax:
InDay (timestamp, base_timestamp, period_no[, day_start])
Return data type: Boolean
Arguments:
| Argument | Description |
|---|---|
| timestamp | The date and time that you want to compare with base_timestamp. |
| base_timestamp | Date and time that is used to evaluate the timestamp. |
| period_no | The day can be offset by period_no. period_no is an integer, where the value 0 indicates the day which contains base_timestamp. Negative values in period_no indicate preceding days and positive values indicate succeeding days. |
| day_start | If you want to work with days not starting midnight, indicate an offset as a fraction of a day in day_start, For example, 0.125 to denote 3 AM. |
Example 1:
inday ('12/01/2006 12:23:00', '12/01/2006 00:00:00', 0)
Returns True
Example 2:
inday ('12/01/2006 12:23:00', '13/01/2006 00:00:00', 0)
Returns False
Example 3:
inday ('12/01/2006 12:23:00', '12/01/2006 00:00:00', -1)
Returns False
Example 4:
inday ('11/01/2006 12:23:00', '12/01/2006 00:00:00', -1)
Returns True
Example 5:
inday ('12/01/2006 12:23:00', '12/01/2006 00:00:00', 0, 0.5)
Returns False
Example 6:
inday ('12/01/2006 11:23:00', '12/01/2006 00:00:00', 0, 0.5)
Returns True
Example 7:
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.
This example checks if an invoice date falls at any time in the day starting with the base_timestamp.
TempTable:
LOAD RecNo() as InvID, * Inline [
InvTime
28/03/2012
10/12/2012
5/2/2013
];
InvoiceData:
LOAD *,
InDay(InvTime, '28/03/2012 00:00:00', 0) AS InDayEx
Resident TempTable;
Drop table TempTable;
The resulting table contains the original dates and a column with the return value of the inday() function.
| InvTime | InDayEx |
| 28/03/2012 | -1 (True) |
| 10/12/2012 | 0 (False) |
| 5/2/2013 | 0 (False) |
