In OData, you can use the $filter query option to filter data based on certain conditions, including date filtering.
Example:
Suppose you have an entity called “Orders,” and it has a property called “OrderDate” representing the date of the order. You want to retrieve all orders that were placed after a specific date, let’s say January 1, 2023.
The OData URL for this filter would look like:
/Orders?$filter=OrderDate gt 2023-01-01
In this example:
/Orders is the endpoint for the “Orders” entity.
$filter is the query option used to filter the data.
OrderDate gt 2023-01-01 specifies the condition. It filters orders where the “OrderDate” is greater than (after) January 1, 2023.
In OData, filtering based on date and time typically involves using the format ‘yyyy-MM-ddTHH:mm:ssZ’ to represent date and time values, where:
- ‘yyyy’ represents the 4 digit year (e.g. 2015)
- ‘MM’ represents the month number with leading zero (eg.04)
- ‘dd’ represents the day of the month as a number from 01 through 31
- ‘HH’ represents the 24-hour clock hour, with a leading 0 (e.g. 22)
- ‘mm’ represents the minutes with a leading zero
- ‘ss’ represents the seconds with leading zero
Example:
Suppose you have an entity called “Events,” and it has a property called “EventDateTime” representing the date and time of the event. You want to retrieve all events that occurred after a specific datetime, let’s say February 15, 2023, at 3:30 PM.
The OData URL for this filter would look like:
/Events?$filter=EventDateTime gt 2023-02-15T15:30:00Z
In this example:
/Events is the endpoint for the “Events” entity.
$filter is the query option used to filter the data.
EventDateTime gt 2023-02-15T15:30:00Z specifies the condition. It filters events where the “EventDateTime” is greater than (after) February 15, 2023, at 3:30 PM.
