I am using version 3.0 and above. Below is my code where i want to join two layers. I didn't get any error but the Charting Layer doesn't show update on fields. I need to join UPI field of Excel file with CHART_UPI field in tab file.
It works but supposedly it will automatically update the column field in Charting Layer after it successfully joined but it remains the same. I need to save and close QGIS and open it back then, it reflect the updated VIS column in the Charting Attribute Table. How can i make it automatically show the updated attribute table after it successfully join?
