Your SQL pass, so it is somewhere in the library. The problem is how to
find in the big data where exactly. I am now going one character by each
other, because it is probably only one specific record kind doing that.
I was able to compile the library under linux and running strace looks
like
So I was able to identify the record doing the problem. I have tried to
find what is so special on that record and it is size 20 characters.
When I have this 3 examples with last name lenght 19, 20 and 21
characters only the size 20 crash.

Hi Milan,
thx for your patch.

I try to apply it for testing:
but seem nothing change .
However I leave it in the code to allow you to test.
I submit also a new dll.

I have a table, Transactions, with a column , Value, of type NUMERIC. The
Value column is supposed to have 2 decimal places in all rows but some have
only one.
To correct this I issued the following command:

Hi Peter,
From https://www.sqlite.org/datatype3.html:
"When text data is inserted into a NUMERIC column, the storage class of
the text is converted to INTEGER or REAL (in order of preference) if
such conversion is lossless and reversible"; basically any fraction you
insert into a NUMERIC

SQLite has no formatting inherent to the column value, there is no such

My application does that. This is how users find out that their settings

So far it is just reported and then the config database is restored from last

I was under the impression that shared cache has performance benefits when used
in a MT environment.
I have enabled the error callback and it logs everything except SQLITE_SCHEMA
and SQLITE_OK.
In the log files I have received so far, none of these were reported (I use
special headers to identify SQLite errors because log files are often several
hundred MB in size).

Hi Richard,
Like said, we've already tried:

x (price); SELECT * FROM x ORDER BY 2
but it also takes 30 seconds; for some really esoteric reason, CREATE

I dump the output to the log file so when a user sends me a log after the
diagnosis reported a ?repaired? damage, I see one or more entries like:
?row 2481 missing from index idx_settings_sndidmnun?
I will see if I can collect more log files in the coming months.

Thanks to all for explaining my confusion. The printf solution seems like
the best way to handle this since I don't need to worry about how many
decimal places are in the number.

Hi Matthias,

You should be also aware of a more common pitfall: unclosed result sets.
Any lock is held until you read PAST the last row or you call stmt_finalize

There is also a more obscure side-effect exhibited by sqlite only: if
you issue consecutive unfinalized select statements, it never releases
the write lock (although they should be atomic), but it does trip the

Hi,
I have a normal table, and a fts table that are joined by rowid's. E.g.
when I add a row to the normal table, I add some values into the fts

recommended).
Now I have restructured the normal table (i.e. delete column) using
