If you run the Aggregate/Advanced SQL in the studio can you get results?

Can you also see the data in the database through studio?

Was the database created directly by studio or was it integrated from another source?


If you using an Advance SQL, to execute your query, you follow the below-given instructions to debug the issue.

Test your query in AdvanceSQL by clicking on the Test button and check if you are getting your desired output or getting the same error.

a) In case of an error first of all check, your query if it's correct or not.

b) Check the output of your query, an entity should either match with the table you are querying on or it can be a structure with the same attributes (any mismatch with the number of attributes in the structure and the output of the query will give this kind of error) your query will provide as an output.

c) Check the value of input if you are providing any within the query, as the unexpected value used as filter/condition while querying the database with AdvanceSQL may also give such error at run time.

I hope this might help to resolve the issue. If not please provide more details as asked by Jose in the above comment.


What upgrade you made?
