After an sql table update i get errors in the dashboard

[Anonymous]

2 days ago I have added a new column to a table in my sql database. 

After this was done errors started occuring with that table in the dashboard.

Please have a look at the error indicated by the following picturessource errornavigation errorrefresh error

There are no errors or any syntax problems with that table in the SQL database. 

Only a single column was added.

The tables can be previewed, downloaded and displayed on the SQL database without any problems.

Can someone help me out or identify what needs to be done to solve the problem please? thank you.

@Anonymous , Add that table as a new table. Open advance editor takes that code and carefully replace/merge it with old table code.

Later you can remove the newly added table
