Hi,
We've being working with SQLite version 3.6.22 in our project and we
wish to upgrade it to the latest one. During the tests with the new
library version, we noticed a strange behavior related to a trigger
which updates the last inserted row. We where able to simplify the
data model and produce a test case which can be executed using the
sqlite3 shell. Here are the outputs:
Execution with latest SQLite 3.7.9:
c:\>sqlite3shell.exe -init .\test_case.sql ":memory:"
-- Loading resources from .\test_case.sql
Expected result: 31|10
Problematic result: 31|0
31|0
SQLite version 3.7.9
Enter ".help" for instructions
Enter SQL statements terminated with a ";"
sqlite> .quit
c:\>

31|10
SQLite version 3.6.22

sqlite> .quit
We are using the amalgamation version of the source for both libraries
and here are the compilation defines:
TEMP_STORE=3
SQLITE_THREADSAFE=2
SQLITE_DEFAULT_CACHE_SIZE=65568
SQLITE_DEFAULT_TEMP_CACHE_SIZE=65568
SQLITE_MAX_ATTACHED=30
SQLITE_ENABLE_COLUMN_METADATA
SQLITE_ENABLE_UNLOCK_NOTIFY
The error was also reproduced on the original library available for
Ubuntu 10.10.
Additional information is available in the test_case.sql script
comments.
Thanks for the assistance.
Regards,
Alessandro Merolli.
