I have a data file that contains current meter data for multiple days.
I am trying to use the Processing Modeller to extract a single days worth of data for further manipulation, using the
Extract by Expression algorithm.
Building my model, I select the input later using a vector feature parameter definition. I then used String parameter definition to input the required date
'25/12/19' and the date field
When I run the model, nothing is extracted to the result layer.
I'm sure it's probably a syntax problem, but can't figure it out.
