Try this,

It will retry the EXCLUSIVE lock each time a page that is not
in the cache is required by SQLite (a cache-miss).
If SQLite doesn't require to read any pages but only adds new pages to
the file does it count as cache-miss?

Hi,
We are compiling sqlite 3.6.23.1 with the SQLITE_OMIT_WSD compile time flag
turned on. We are using the amalgamation. We found that this didn't
completely eliminate the writable static data in our binary, and some
investigation led me to this static variable:

Yes.

Somewhat off-topic, but if you want truncation, this would do it: round(x -
0.5) .
Actually, cast(x as integer) works better. It

Thank you very much. Both replies pointed to indexes. So I changed
the indexes and markedly improved performance from 12 seconds to about
1.5 seconds for the faster variant (using nested SELECTS) and about
2.2 second for the slower variant.

Now on the table phonebook I can do a query:
SELECT rowid FROM phonebook where last_name = Smith and first_name =
John;
That's good to now about the automatic rowid. I can certainly create a
new column in phonebook that shows the row number with id INTEGER
PRIMARY KEY AUTOINCREMENT. However, I'd really would like to do the same
thing in a view.

Hi Dan,
It doesn't matter that it will never be written to. Since the variable is a
non-const static it will get mapped into the WSD portion of memory.
There are actually a few other global static variables that are getting
placed in the WSD section of memory.
Here is a list of non-const
