I'm having hard time to store and retrieve data with SQLite. Let's
assume I have this structure in my C code to hold my data
struct foo {

float b;
char c[1024];

The difference is purely stylistical. According to

While experimenting with several different ways of structuring the query
referenced in "Improving Query Performance", I mentally raised a
question I hope someone can answer.
The following two queries appear to be functionally equivalent...that is
to say the results they produce are identical.
Interesting. I suppose these variable results are because of each system's
localtime() function?

Yes. I'm sorry. My fault. Wrong format. I used /MM/DD.

Use a LIMIT clause instead of TOP:
SELECT * FROM table LIMIT 2;

Hi all,
I have a big table and I want only select the first 2 rows.
I have tried this :
select top 2 from table;
but it doesn't work! Any help please.

Hi
I'd like to ask a question about 2038 year unix problem.
I've found a mention about it on on
http://www.sqlite.org/cvstrac/wiki/wiki?p=DateAndTimeFunctions wiki page.
Though I cannot grasp the idea of the following phase:
"Also, the localtime() C function normally only works for years between
Sqlite 3.6.10
Background
I have the following abbreviated case:
CREATE TABLE sequence_elements (
sequence_element_oid integer primary key autoincrement,
sequence_element_name varchar,
definition_parent varchar,
instance_parent varchar,
soft_deleted_char varchar default 'F' )
C
Just throwing this out there ... how about the 'try / catch' construct in
'c++' ???

Hi,
I noticed that the (recommended) amalgation version 3.6.12 does not contain
the new .genfkey functionality, while the (not recommended) full version does.
Is this on purpose?
