Subject: [Qgis-user] Virtual Layer query with "currentExtent" not working 
anymore

A while ago, I figured out how to limit a query on a layer by the

current map extent as a preparation for another query:

SELECT * FROM ASK_Geometrien WHERE

st_intersects(ASK_Geometrien.geometry, currentExtent());



Now, when I try it again later, the test fails with "no such function:

currentExtent"

Hi Bernd,
AFAIK there is no currentExtent() inbuilt function.

You need to define a custom currentExtent() function that returns the current 
extent.

Please see, for example: 
https://gis.stackexchange.com/questions/303325/how-to-speed-up-a-query-in-a-virtual-layer-of-qgis

Best regards.
