If you store NULL then SQLite will return NULL. Maybe your presentation layer
is converting NULL to text.
The literal NULL is used in the query text, or you can call sqlite3_bind_null()
for a parameter or sqlite3_result_null() to set the result of a user written
function.

Thank you for your reply. I have SQLite running on a dual-boot
Win7/Fedora28 machine, and I have already investigated FMPro v.2,3 and
5. I have not tried installing any version of OS X, however; that will
be my next avenue of exploration.
Thanks once again for your assistance.

RTM.
Sqlite3_total_changes() counts the *total* number of changes done since the
connection was opened. To get the number of changes made by the *last
statement*, use sqlite3_changes(). This applies only to connections that are
not shared between threads.

Show what you executed. Make sure that there is no interference from other
threads on the same connection. If you execute more than 1 statement in one
call to sqlite3_exec(), only the last INSERT/UPDATE/DELETE will determine the
return value of sqlite3_changes(). If you want the aggregate
Hi team,
How we can find the number of changes done on a particular table in DB using
sqlite3 library function (C program). I tried with sqlite3_total_changes() but
its doesn't helps me. I am writing only one record but its giving me 22
records. At present my db contains 23 table and i tried

Just as I said. You are executing *TWO* SEPARATE *INSERTS* OF *1 CHANGE* EACH.
So sqlite3_changes() reports 1 change (from the second INSERT), just as it is
supposed to.
If you call sqlite3_total_changes() before executing the inserts and again
afterwards, the *difference* of the returned

Thanks for reporting this. The bug was that table and column names
