+`INTERVAL` is *deprecated*. Please use `INTERVAL_YEAR_MONTH` and
`INTERVAL_DAY_TIME`
+as a more precise representation per [ANSI SQL
Standard](https://www.ibm.com/docs/en/informix-servers/14.10.0?topic=types-ansi-sql-standards-datetime-interval-values).
Review Comment:
I wouldn't say either IBM or Oracle are definitive on the ANSI SQL standard?
(The problem being that the spec is not freely available to any of us, so this
becomes a "trust what I'm saying" situation w.r.t the spec's wording...)
