I'm hoping someone can help me with this. Using Visual Studio C++, the
following code DOES create the DB file. But the table doesn't get created and
I'm stumped as to why it won't create the table. SQLiteConnection conn;

You could set a flag nothing that parameters have been optimized out, so the
statement author can be warned. Where to encode the flag? Maybe in some
opcode's unused parameter?

This is extremely annoying behaviour, unexpected and non-obvious.

I was searching for any reference to reserved characters used in FTS4, but

I just had an amusing realization... if SQLite itself won't change,
then the problem falls on the shoulders of System.Data.SQLite, which
is incidentally also handled by this mailing list. It's ultimately
this code that is causing the problem because of the case mentioned
here:

The generated limit parameter does have a value of 1, so it's a valid
query. It's SQLite that has taken this valid query with a valid
parameter value of 1 and has exposed its internal implementation
details by removing it and causing additional work-arounds in
parameter binding. It's possible the

Have you considered using virtual tables so that the calculations are done

Hellow folks,
At $work we have an application that processes *huge* (tens of millions of
rows in some of the larger tables, sometimes over 30GiB file size). This
application changes and when it does, it drops some tables and calculates
them again. What is somewhat surprising is that dropping the t

ALTER TABLE ADD COLUMN does not drop data from the table.
"Alter table add column" command drop data from table.
Can you keep the data or should I store the data before the alter and then put
them in the table?

I would ask one more question: do they have the same Windows and .NET
Framework version as you have? AFAIK, Windows and .NET specifically
are very picky on all dlls versions. So if for example you have
SQLite.Interop.dll compiled with a newer .NET Framework and manifest

Unfortunately you're also hitting a rather lousy error message which doesn't
