Tableau error connecting to local MySQL db
asked Oct 7, 2022
Windows Server 2008 Tableau Desktop 7.0 Local MySQL database using Xampp
When attempting to connect to a localhost MySQL database server using the native MySQL data connection in Tableau Desktop, I'm getting the following error:
"The connection to the data source might have been lost. Communication with the Tableau Protocol Server process was lost.
Unable to connect to the server "localhost". Check that the server is running and that you have access privileges to the requested database. Unable to connect to the server. Check that the server is running and that you have access privileges to the requested database."
When using "Other Databases (ODBC)" in Tableau, I am able to connect and return data. However, I would prefer to use the MySQL connection to avoid the limitations of the Other Databases connection.
I created a specific username in phpmyadmin as well as tried using the root username and password and the same error was returned. I created a user DSN in odbcad32.exe and attempted using multiple versions of the MySQL ODBC driver (3.5, 5.2.7, 5.3.4).
Does anyone have any ideas of what might be causing the error? Really appreciate any help.
Tableau error notation in brackets meaning
asked Sep 28, 2022
In Tableau I received the following error message:
The Google BigQuery service was unable to compile the query. Name Field1 is ambiguous inside Custom SQL Query at [62:33]
My BQ Query seems to work fine in BQ, but when copy paste in Tableau the above error shows. In order for me to track the error, I want to understand the error message.
What does [62:33] refer to? My query is only 47 lines of code, so I can't really seem to grasp the meaning of this notation...
