Error when refreshing dataset - "Unable to get tables."

I've not seen this error before and I'm unsure how to resolve other than dropping and recreating the dataset.

I have a dataset that has been established for a few months. It uses a SQL query versus a specific table. Over the last several days, we have seen error notifications that the data cannot be refreshed when our primary workflow kicks off.

When I try to refresh the data manually, it gives an error "Unable to get tables." and both the Configure and Apply buttons are greyed out.

I've tried editing the definition and can do so successfully, but with no changes to the error. The only thing I haven't done yet is drop and recreate the dataset.

Are there other steps I can take to troubleshoot this further? If my only other option is to drop and recreate the datasets, what impact will it have on our workflows? Will I need to update them, or will they still work as long as I use the same names for the datasets?

    Hi George,

    I've not heard of this error before either. Checking the code shows that it's caused by an general exception but fortunately we write much more information about it to the log file. Could you take a look in there and find the corresponding section, or just send the log file to me and I'll take a look for you. There should be enough in there to help figure out what's going wrong.

    The log file can be found in the repository directory under data/log/datastudio.log

    Many thanks,

    Ian

    @Ian Hayden , thank you for the help.


    For awareness to the community, the log file helped us solve this issue. The table names referenced in the SQL Query used as the source of the dataset had changed in our database. The log file contained the SQL errors that stated "Invalid object name". We corrected the names in the SQL Query and were able to successfully refresh the data.

    @Ian Hayden , sorry for the delay in following up; I've been working with our system administrators to get a copy of the file to send to you. What is the best way to get a copy of this to you for review?

    Hi George,

    You should probably be able to zip the log down quite small and attach it to an email. If you send it directly to me I'll take a look. My email address should be in my profile.

    Regards,

    Ian

    I just emailed; also working with the system admins to get the latest file this morning right after I attempted to refresh the data for 3 tables and received the same error.
