I know from experience where parameters work (SELECT, INSERT and
similar; also ATTACH as one of my projects happens to use it this way),
and where they don't (all forms of CREATE; I haven't tried ALTER but I'm
99% sure it won't work there either). I've just tested PRAGMA. I briefly
scanned the rest at http://sqlite.org/lang.html to confirm that their
syntax doesn't involve expressions.
I do not mean to be argumentative here, but I think the documentation on
this leads to a different result. If you examine the syntax diagram for
"create view", it refers to the construct 'select-stmt', which in turn
refers to the construct 'expr'. (See
http://sqlite.org/lang_createview.html ,
http://sqlite.org/lang_select.html , http://sqlite.org/lang_expr.html )
There, one alternative for expr is given as 'bind-parameter', which
seems to not be defined under that name. However, the same page on
'expr' defines parameters. Since using parameters in a view appears to
be allowed by the syntax diagrams, and since I saw nothing to the
contrary where it logically should appear (as a semantic exception to
the syntax), I went ahead and tried to use them in a view.
