You can receive a "column not found" error if the columns in an analysis are
missing from the Athena data source.
In Amazon QuickSight, open your analysis. On the Visualize tab, choose Choose dataset, Edit analysis data sets.
On the Data sets in this analysis screen, choose Edit near your dataset to refresh the dataset. Amazon QuickSight caches the schema for two minutes. So it can take two minutes before the latest changes display.
To investigate how the column was lost in the first place, you can go to the Athena console
(https://console.aws.amazon.com/athena/
If this error happened when you were editing a custom SQL query in preview, verify that the name of the column in the query, and check for any other syntax errors. For example, check that the column name isn't enclosed in single quotation marks, which are reserved for strings.
If you still have the issue, verify that your tables, columns, and queries comply with Athena requirements. For more information, see Names for Tables, Databases, and Columns and Troubleshooting in the Athena User Guide.
