That's a fair concern. In actual usage, however, the vast majority of hallucination (>90%) tends to be:

- phantom tables and columns, in which case the query will fail

- incorrect syntax for date functions (i.e. the wrong flavor of SQL)

And we tend to see less of this type of hallucination when there are lots of example SQL queries that have been "trained" into the RAG system.
