This always means that the reader syntax is not enabled where this is
being read.

Where did you use the enable-sql-reader? in the repl?

The issue with those macros is that after the first enabling, the system
keeps track that it is enabled and future calls don't do anything. To
reset this, call disable a number of times.

Alternatively, you can use FILE-ENABLE-SQL-READER-SYNTAX which forces
the enable without regard to the current status-- it is named file
because that's the primary use case of it (and when used at the top of
the file behaves really nicely), but it is the only enable macro I ever
use. This macro doesn't attempt to keep the previous state and when
using it at the repl, i always just want to turn it on, and then never
care about turning it off later.
