Sure; I've already worked around the problem. But why make it a problem? I'm sure there are ways you could work around the absence of "IF NOT EXISTS" in the simple "CREATE TABLE" case too. So why have the clause there? Because it's clearly useful for the SQL programmer to be able to specify that they just want a table to exist, rather than specifically to be created. >> Also, what is the recommended way to build sqlite3 if you want to make >> changes to parse.y, given that using the complete source tree tarball >> is heavily recommended against (in favour of the amalgamation, which >> only contains the generated code)? > > The amalgamation is effectively 60 or so source files all concatenated > together.

I don't particularly want the latest changes; I just want to use the latest stable release. But if I were to build from the trunk, how would I do so? The download page clearly states that "The Makefile and configure script in this tarball are not supported. Their use is not recommended. The SQLite developers do not use them. You should not use them either." Presumably, though, the Makefile and configure scripts in the tarball are just a snapshot of the Makefile and configure scripts in the trunk at the time of release. So what should we use to build the trunk?
