I'm trying to append two queries together. One is from a csv file while the other from an xls worksheet. The data comes up fine in the query editor but when I try to Close & Apple, I get the following error:
Geography
Column 'Column1' in Table 'Geography' contains a duplicate value 'ACSSF' and this is not allowed for columns on the one side of a many-to-one relationship or for columns that are used as the primary key of a table.
The column above just contains data. I haven't defined any relationships or created any models. I'm just trying to append the rows from one query to another.
Solved! Go to Solution.
Hi @Adam_123
from simple data models relationships are defined automatically.
So, first remove relationships in report mode then do you appen workaround in Query Editor
