Splunk DBConnect 3.1.1 Build 34 There was an error processing your request. It has been logged (ID XXXXXXXXXXXXXXX).

[bradob]

After completing the SQL Query and then setting the properties for an input, I cannot click the finish button without getting the following error:

There was an error processing your request. It has been logged (ID 7af858e1614ada9e).

If I click on it again I get a different ID. Tried going through the logs, did not see anything pointing to why it won't complete the process.

Anyone else get past this?

Hi @bradob,
You probably need to check below troubleshooting steps for dbconnect in splunk docs.

How are you authenticating? Not all MS drivers work with all authentication methods. You may need to experiment to see which driver works best.

[bradob]

I have validated the authentication and run a basic query. Credentials are authenticated locally to the SQL database. Once the query got complicated is when the error is occurring. Is there a limit to how in depth the SQL query can be? A basic select * from table works. Once I started doing inner joins and calling other tables from the database, renaming columns is when it wouldn't let me complete the process. Just note that the SQL query does complete successfully before going on to the next "page" where I choose how often, and have the option to "finish"

[richgalloway]

Given that, I'd say your query is probably too complex. IIRC, DB Connect throws your query into a "SELECT * FROM (your query here)" statement. You can try that directly on the DB to see what results. Also, turning on debug logging in DB Connect should show more about what is happening under the covers.

One way to simplify the query is to put the complicated bits into a view and invoke the view from DB Connect.
