There seems to be an issue with the current upgrade and the connection to a MS SQL database, I have try just creating a new app with just a connected database and had the same issue.
The Direct database connection does not show any errors.
This could be an issue with the table name aliases when creating/saving database queries. Try running the queries after removing/deleting aliases in the DB Query Builder. You may need to remove the aliases again after making any changes to queries, as these get re-added.
Yes the queries are not able to pull the information however the problem is occurring without any queries, I tried an app with only the database connected and nothing else. I tried a view/edit directly on the tables which produce the error. I have checked the tables and there doesn’t appear to be anything wrong, the other issue is that the tables worked on a pervious version of Wappler without fault. The database is a Microsoft SQL, I am interfacing with ASP.NET
I have spent a bit of time going through and having a look it appears that it may have something to do with the dbo. at the beginning of the database names, I have some customized queries that do not have the dbo. in the sql and they run like a dream. It appears that the sql does not like the DOT in the sql statement. There is the odd case where the dot did not appear to matter, which has lead me to some confusion.
