I've inherited some python and sqlite work and am trying to figure it out. I've
done neither before, so be kind.
There are some python scripts that generate a sqlite db, then our app has uses
sqlite3 code library to read that db and copy it to a memory-based db (I assume
so we can make changes

Seems like any

read/write

So I think what you need to do is to first PRAGMA page_size on the
read-only disk database to find out what the page size is there. Then
PRAGMA page_size=N (substituting an appropriate N) as the very first
thing you do on the in-memory

This does not return a simple character string, but a table with one row and
one column. Might you have to extract the value from that table ?

I'm some progress, but not sure why the error is being returned below.
const int flags = SQLITE_OPEN_READWRITE | SQLITE_OPEN_CREATE;
const int result = sqlite3_open_v2(:memory:, m_dbh, flags, NULL);
// stmt.m_sql is a UTF16 string: PRAGMA page_size = ?. It will
// bind the actual value (4096) to
err = sqlite3_prepare16_v2(m_dbh, stmt.m_sql.c_str(), -1, stmt.m_stmt, NULL);
err - SQLITE_ERROR
If I manually set the string to PRAGMA page_size = 4096, then it works. So
perhaps this code is doing it wrong. I copied an existing routine that
somebody else no longer with the company wrote.

Can't prepare

Can't prepare and bind a PRAGMA command like that. You'll have to

Ah, there we go. Copying existing code only works with the existing code works.
:) Thanks everybody! I wish all mailing lists were as responsive as this.
