- One is tempted indeed, to solve this problem using an private, fixed-named
- view, e.g. create a temporary table with a variable user dependant name, and
- then a (temporary) view, having a fixed name. So you can use repeated inserts
- without hard-coding tablenames, it looks.
-
- But beware: QEP's of repeated queries are stored in the server (translating
- the view definition of its first occurrence). Another user subsequently
- issuing the same repeated insert (after having created his own view) uses
- this same qep, and will try (in vain of course) to insert into the temporary
- table that is owned by the user whose qep is stored in the server.
