the way I do it is:

set table1.f1 =
(select table2.f1 from table2 WHERE table1.f0 = table2.f0)
where exists
(select * from table2 WHERE table1.f0 = table2.f0);

Francisco,
You might want to add a coalesce() call so the f1 value is only changed
if there is a corresponding value in table2.
update table1
set f1 = coalesce((select f1 from table2 where table2.f0 = table1.f0), f1)

OK, the DBD 1.11 install creates a SQLite.so Library.
There is ONE in the perl site install directory.

The strings command finds version 3.2.7 in BOTH files.
Where else could perl possibly be finding a SQLite library?

What version are you using? The "IF NOT EXISTS" clause only exists in SQLite

Ok, a VERY VERY strange error, which I can't solve.
I use the SQLite.NET wrapper from www.phpguru.org to use it with C#.
I have the following query:

"password VARCHAR(100) " +
I'd assume that something like that is exactly what's happening since
the problem only happens after a reboot, although I was thinking that
sqlite was caching it to a temp file or something. I'm running
Windows XP Pro but I haven't done anything to change the default
behavior of the os.

Good for one-off statements, like DDL. If you have to generate the SQL

If your application runs the same SQL statements more than once, use

Frankly, I'm a bit surprised that you seemingly never were in contact

(btw similar) solutions to your problem.
Some of the libraries also have more unified interfaces to different
backends (also sqlite).

Hi David,
if you're looking for a truly portable tool, you should consider
Tcl/Tk. SQLite has a builtin interface to Tcl, Starkits are portable
between many OSes without any code change and the tktable widget
ot tablelist should be what you are looking for to present your data.

David,
What you're looking for is an editable data grid. They're common
components and fairly easy to find. They're also typically a pain in the
tail. If you're comfortable with C++ you might look at wxWidgets and
their built-in datagrid.

This is probably off-topic for this list, so let me apologize in advance
