That will make it harder to work with Teradata, unless things have changed in the past 5 years.

We used to create small permanent individual or team databases for users so that they could store things temporarily.

It was especially important when needing to upload some data into Teradata so it could be used to drive the Teradata queries.  For example to upload a set of IDS to use to subset from the large database. With a permanent table you could use BULKLOAD (fastload?) feature and so jobs would run much faster than when trying to copy the same amount of data into a volatile table.

Have you considered using CTE(s) instead of Volatile Tables in Teradata?

If you only want to derive subset of data based on information held in another derived table/query, CTE might be a better option!? The above two links might provide you with some insight.

Disclaimer: I have used CTE(s) before with Snowflake but not Teradata.

 

Hope this helps,

Ahmed
