Dear All,
I am trying to store certificate related DER encoded data using sqlite
database??
But what kind of datatype should i use in sqlite to store and retrive DER
encoded data??
Is there anyway to store the DER encoded certificate related fileds in sqlite??
Thanks in advance..
Samrat
Still, I think backwards compatibility and consistency with other databases
would be most important in this situation. I just checked MSSQL and it's
same as current sqlite which uses the first select statement's column names.
It doesn't just affect order by too.. based on the standard SQLite

That's not what the standard says. It says the name

Besides, the current version of SQLite seems to match on the first tables

Gerry,
I took a look at this and I don't see how it works.
I believe I would have to do the following:
Make TEMP copies of all of the tables that are being modified.
Upon COMMIT:
Delete the old tables
Rename the temp tables to the old tables
COMMIT
I don't see an easy way to do
Andy's answer and explanation is consistent with my experience and
expectations too.. mostly from MSSQL and Access background.

My understanding is:
select a, b from t1
union
select b, a from t1
is equivalent to
select a as a, b as b from t1
union
select b as a, a as b from t1
And therefore, the first sql statement controls the resulting column names,
and the order by applies to the column names (transitively)
Consider this query:
SELECT a, b FROM t1 UNION SELECT b, a FROM t1 ORDER BY a,b;
Is the query above equalent to:
(1) SELECT a, b FROM t1 UNION SELECT b, a FROM t1 ORDER BY 1,2;
Or is it the same as:
(2) SELECT a, b FROM t1 UNION SELECT b, a FROM t1 ORDER BY 2,1;

I am trying to build the test files under VS2005
I've created a new project and added all the test files with additional
libraries for TCL and the sqlite3 libraries.
All compiles fine, with the exception of the following errors

Autonomous transactions:
ie
begin
begin autonomous txn1
commit;
commit txn1
This transaction has no impact on the outer txn. I believe it can commit
either in or out of the parent transaction as well Quite a bit more
complicated
What do you want to measure?

We use a very simple data retrieval method for smallish datasets. The
data is just stored in memory or as a memory mapped file and a
sequential search used. It sounds crude but when you use a fast search
algorithm like Boyer-Moore it outperforms index methods up to a
surprisingly large
