Hello
Thank you for you quick responses.
If I disable the index with + it takes around 50% more execution time.
I supposed a very fast query even with many records, because COUNT( ) might do
its work on the index only.
I this case, I have to find another solution to get the number of records
Hi all,
I have an application where users can tag news stories with custom tags. I
present the latest 20 stories along with all of the tags the user has
applied. I wind up with a three-table schema and in order to get all the
stories with their tags at once regardless of whether a story has a tag

I guess you mean "... the **count**" and not **size**.

I have a small script which shows this problem: if I run it from the command

first).
The database has permissions

Well, it does, but the work is still proportional to the number of
records counted. The index helps to quickly filter out

Yes, you are right - my fault. Sorry!

what would cause this? Any ideas on how to resolve?

SQLite is attempting to fsync() a directory after unlinking
On earlier versions of AIX Sqlite has no issues. This problem might not
be inherent to AIX V5.3.

Hi everyone,
I have an issue with datetimes that doesn't return the "time" part
correctly (always 00:00:00 or 18:00:00) when I use SQLite in my C++
code. Whenever I use datetime('now'), or current_timestamp, the time is
not correct. However, it works correctly when using the sqlite3
Hey all,
Over at mozilla, we have an interest to keep other applications from
writing to our database. To accomplish this, we open the database
with an exclusive lock using the locking_mode pragma. However, this
means other processes cannot even read our database. What we'd like
to see is a

This might be an error on my side since the normal .db handling seems to
function ok.
The main .db is opened using sync_mode=off. So I shouldn't even get this
particular error.
I'll dig deeper into this and post more info once I validate the source of the
error.

Ok this is really weird.
One sqlite Db functions fine.
A second db (connection to a different db) commits and does not delete the
journal file. I have verified that data is being written and the journal does
indeed have the original blocks.
Where in the source does sqlite make the decision
On the second commit I found that the locking_mode=exclusive caused the journal
to merly be truncated vs deleted.
I put the locking mode back to normal.
It looks like the IOERR_DIR_FSYNC is due to the fact that a MJ journal is not
being created! Pragma synchronous=OFF was in effect. The same
Preprocessor Macro:
#if defined (_AIX)
Looks like the MJ file is not getting created, sqlite 3.5.9 This is also
reproducible via the command line: Possibly an issue with the journal mode code
that was introduced.
SQLite version 3.5.9

From what you describe, it seems that the compiler is performing
single-precision, rather than double-precision, math. After

This wrapper looked really promising. But, the SQLite backend wasn't
being maintained and is no longer officially
