Filter by date ranges
Filtering data by date ranges is as simple as filtering any field with comparison operators. This example queries survey records where the customer response date was between February 1, 2019 and June 1, 2019. The date must be formatted as yyyy-mm-dd.
feedback operations, when you are filtering by a specific timeperiod, run your query several hours after the period ends to ensure completeness. 10 hours is usually a good delay.Data query
query getData($filter: Filter){
feedback(
filter: $filter
){
nodes{ #object with data
fieldData(fieldId:"e_responsedate"){ values}
}
}
}Variables
{
"filter": {
"and": [
{"fieldIds": ["e_responsedate"], "gt": "2019-02-01"},
{"fieldIds": ["e_responsedate"], "lt": "2019-06-01"}
]
}
}Using relative dates and periods
The example above shows absolute dates, but relative dates and date ranges can also be specified in the queries. Use relative dates to perform date calculations and get expressions such as "the first day of the month in which start date occurs" or "the day after start date".
Use relative expressions to represent any subset of the time coordinates in relation to the local date. This relation is expressed replacing the fixed coordinate values by parenthesis and a signed offset. For instance if today is May 25, 2019 then the expression (+0)-(+1)-10 represents the June 10 (next month) for 2019 (current year).
Expressions can include ceiling/floor rounding to a given time unit. For this the date should be enclosed by a rounding function which is named like the time unit with a prefix sign which is "+" for ceiling and "-" for floor.
The following table lists example date patterns for relative date expressions.
| Date pattern | Result when today is 9 July, 2019 | Description |
|---|---|---|
| (+1)-05-25 | 2020-05-25 | Year 2020 = (2019 + 1), month 5 and day 25 are given as absolute |
| (+0)-(+1)-25 | 2019-08-25 | Year 2019 = (2019 + 0), month 8 = (7 + 1), day 25 is absolute |
| (-1)-(+0)-(+0) | 2018-07-09 | Year 2018 = (2019 - 1), month 7 = (7 + 0), day 9 = (9 + 0) |
| 1982-(+0)-(+0) | 1982-07-09 | Year 1982 is absolute, month 7 = (7 + 0), day 9 = (9 + 0) |
The following table lists actual dates for various date ranges with rounding in effect.
| Date pattern | Result when today is 9 July, 2019 | Description |
|---|---|---|
| +month(2018-05-25) | 2018-05-31 | 31 because that day is the end of the month |
| -week(2018-05-25) | 2018-05-20 | 20 because that day is the start of the week |
| +Year(2018-05-25) | 2018-12-31 | 12-31 because that is the end of the year |
| +QUARTER((+1)-05-25)) | 2020-06-30 | Year 2020 = (2019 + 1), month 6 and day 30 because that is when the quarter ends |
| +WEEK(1982-(+0)-(+0)) | 1982-07-10 | Year 1982 is absolute, month 7 = (7 + 0), day 10 because that day is the end of the week. |
This example queries survey records where the customer response date was between February 1, 2019 and March 31, 2019 (the end of that quarter in the calendar year).
