Allow post-join computed columns for columns that begin with underscores
When a column starts with an underscore, it cannot be used in a post-join computed column. For example, this column is defined for every record in the table:
However, the preview fails when it is used in a post-join computed column formula:
Other columns beginning with underscores that I know are fully defined have the same issue. Running the recipe anyways results in the following error:
[Teradata Database] [TeraJDBC 16.20.00.12] [Error 2620] [SQLState HY000] The format or data contains a bad character.

This is a requirement for me to upload items to my database, since the required meta attributes all start with an underscore. I cannot change this. It is less than ideal to replace my entire database to accommodate an issue that Dataiku has, so I am trying to help them and others.

Again this is fairly trivial to bypass. Use the column without underscore in your flow. In the final output step rename it to have an underscore.
