It also works for me on linux. I'v looked what is happening on vista and it
doesn't crash but silently exists. fgets() in local_getline() is returning 0
when n is 0. My problem with small nField

It's very easy to cause malloc failure on 32
I find those diagrams less readable than text version. There are
other problems besides my personal preferences:
- text cannot be copied from pictures
- syntax cannot be viewed with text-only browsers
- site loads a little longer (there are still people that don't use broadband)

I'm not sure about performance, but I assume that static typing might reduce
memory usage (especially with small caches). Internally every type in sqlite is
stored in structure that takes 64 bytes (little more on 64 bit systems).

I guess your compiler's default stack limit is big. I tested real query on
linux too and it crashed really fast. But satck size was limited by default

I'v read in change log that some stack allocted memory were moved to the heap,
but I think that there is still to much allocated memory on the stack.
After creating a table with 2000 columns, jdbc driver created a query that run
out of stack. Default java's stack limit is low, but it wasn't hard

Sure, but it's not allways a good thing. Usually one column stores related
data.
Related data mostly have the same type. Entering a value of different type is
an error

I know that, but why it does't create appropriate column definition ?

creates a table with "date" type.

This type does't do much, but it can be queried with

On windows this
Is there a reason why ALTER TABLE ADD can add only one column?
I'v changed the parser to allow any number of columns - I'm calling
sqlite3AlterFinishAddColumn() for every column. It seems to work.
Am I missing some problem, or nobody wanted more columns before?

I'v heard about some version of mysql that didn't return rows in the same
order (but haven't seen it myselt). So unless this behaviour is documented
in mysql manual, it's not a good idea to rely on this. Actually I'v seen

It seems like changing

to
nByte = GetFullPathNameW(zWide, 0, 0, ) + 3;
corrects the problem.
According to documentation even that + 1 isn't necessary, and

Can someone tell me why attach cannot be called within transaction? It does

Hi
I need SQLite to be able to acces several tables at the same time. I'v decided
to do this by creating a new database for each table. So far I'v changed
sqlite3StartTable() function - it calls attachFunc() and then changes name to
name.name. It worked - master database is not changed, and
