Opaque URI (opaqueuri)
Description
You can apply this operation either as a Filter or Create column operation:
Filter | Retrieves only opaque URIs from a specified field. |
|---|---|
Create column | Creates a Boolean column that shows true if a given URI is opaque. |
Opaque URIs differ from absolute URIs in that they don't describe a path to a resource. A typical example of opaque URI is a mailto URI (mailto:a@b.com)
How does it work in the search window?
Select Filter / Create column in the search window toolbar, then select the Opaque URI operation. You need to specify one argument:
| Argument | Data type |
|---|---|
| URI (mandatory) | string |
If you use the Create column operation, the data type of the values in the new column is boolean (true or false).
Example
In the demo.ecommerce.data table, we want to get only the events where the URIs in the referralUri column are opaque. To do it, we will apply a Filter using the Opaque URI operation.
The arguments needed for the filter are:
- URI - referralUri column
Click Filter data. Since there is no opaque URIs in the referralUri column, you will see the following result:
To add a new Boolean column that shows true when the URIs in the referralUri column are opaque, click Create column and follow the same steps.
How does it work in LINQ?
Use the operator where... to apply the Filter operation and select... as... to apply the Create column operation. This is the syntax for the Opaque URI operation:
opaqueuri(string)
Examples
You can copy the following LINQ script and try the above example on the demo.ecommerce.data table:
from demo.ecommerce.data
where opaqueuri(referralUri)And this is the same example using the Create column operation:
from demo.ecommerce.data
select opaqueuri(referralUri) as opaque_uris
