To all who replied, thanks for all the help.
Naming the columns in not a problem. It's easy enough to get the column names
and build the appropriate select statement.
Thanks again,

The coalesce(a,b,c, ...) function returns the first of its
To get this effect you need to have 2 (shareable) images, each with their own
and very private copy of sqlite, loaded into the same process.
With the mentioned #defines that make all sqlite3 symbols become static, it is
quite easy to compile sometool.c and sqlite3.c into a single sometool.so

Fine for
I also cannot think of a way to do this without naming columns. If this is
something you have to do frequently from multiple locations, it might be
worth creating a view that does the hard work in one place.

I?m currently implementing a custom FTS5 tokenizer which I?d like to
automatically register for each db connection.
So I tried to register an extension hook with sqlite3_auto_extension but when
my code is called the FTS_* modules have not been initialized, because
sqlite3Fts5Init() is called

The problem only comes up with two different copies of SQLite are
running within the same process. The same program being run

Ok?starting to sound safer. :-)
at a minimum this problem only occurs when multi-threading is being used to
access a sqlite DB file. but I think its probably even more specific then that?
When you say ?two copies of sqlite in the same address space?, this is the part
I am getting confused

Just thinking out loud?.is this problem related to specifically when people try

All,
Is there a simple way to find a row in a table where none of
columns contain a null value? For example:
SELECT * FROM AnyTable WHERE (all columns IS NOT NULL) LIMIT 1;
Or do I have to do this manually in my application scanning
every column in every row until I find a row with no nulls?
