While this is documented (last para of "42.11.1. Variable Substitution"), it's not exactly prominent. Should we move that to somewhere more visible? If so where?
I think the docs are acceptable as-is - especially given the numerous cross-references to that section. If anything i’d maybe call out that most non-result returning commands are actually not parameterized in “42.2.5 Executing a Command with No Result” just before the link to 42.11.1
Concretely, as attached.
I found the comment about the 9.0 behavior to be unnecessary at this point and so removed it.
The wording in the PL/SQL conversion comments is a bit out-of-scope but took a look at it too as it also redirects the user to the variable discussion and I looked at all 4 cross-references.
