My typical use case is trying to determine how many rows I just wrote out
to a file. Window functions are no help because they alter the output
format, which is usually undesirable. It's sort of absurd to run `wc -l`
over the newest 25MiB file in my system to get an answer that's probably

Hi,
According to the online documentation (https://www.sqlite.org/series.html),
generate_series is compiled into the command line shell. As it turns out,
this is not so. It is not even an option in the build system from what I
can tell. It would be nice to at least have a build flag to enable it.

The wrongly-located data was still present afterwards. EventDetails was not

We have an application that we distribute to our clients each of whom
run Windows - often it's a desktop XP machine. Our app consists of a
set of Delphi services and a PHP web front end each of which use ODBC
for database connectivity.
The vast majority of installations have shipped with sqliteodb
& testing the system
carefully when multiple writes may be an issue due to bugs in the file system
locking. Moreover, like sqlite, other databases are known to work well relying on
the system file locking.

I am using sqlite3_column_text16 to retrieve data.
The problem is that sqlite3_column_text16 takes the column number as
argument. This breaks my existing code if I insert new columns in the
beginning of the column list that was specified in the SELECT statement.
I was not able to figure out the

To convert to the older database format:
sqlite334 334.db .dump | sqlite321 321.db
And then perform your timings with both SQLite versions against
the 321.db file to level the playing field.
Just having an index on utime should be optimal for SQLite 3.2.1.
