Right. It can't be done.

Hi,
Why not construct the SQL statement dynamically in the C/C++ code? That way your
statement(s) would have variable column names before compilation.

That is what I do. But that also means I have to call sqlite_prepare() each
time, instead of just once. I was originally hoping I could prepare() once
and just bind.

I try copying a table from a :memory: data base to a file data base, but
could not make it work.
Anybody has any suggestions?
Thanks
I tried something like:
open a data base :memory:
create table MYTABLE (...)
...
attach 'filename.db' as FileDB
create table FileDB.MYTABLE as select *

That's true for SQLite 2.8. But beginning with SQLite 3.0
the restriction is removed and you can create new tables in
an attached database.

I think there might be a bug in this code in lockBtree:
if( sqlite3pager_pagecount(pBt->pPager)>0 ){
u8 *page1 = pPage1->aData;
if( memcmp(page1, zMagicHeader, 16)!=0 ){
goto page1_init_failed;
The problem is if you are trying to open a non-sqlite file that is
smaller than
11 matches
