How are these related to each other ?
Do you want
Greetings.
I need some help from you gurus to have multiple selects, but the sequence is
important. For example,
create table t (a, b, c, d, e);
insert into t values (1,2,3,4,5);
insert into t values (2,2,3,4,5);
insert into t values (3,3,3,3,3);
insert into t values (4,1,1,1,1);
insert into

If it's completely arbitrary I think you are stuck with using union
unless it's an order that you might know beforehand.
Then you can add an extra column with the index.

Just to point out the obvious, have you tried ORDER BY?
"SELECT name FROM table ORDER BY name;" will return your list in
alphabetical order.

Hi,
Just wanted to know can we have multiple quries in a single prepare statement
seperated by semicolons.Something like,
Select count(*) from tbl where name="foo";select count(*) from tbl1 where name
= "bar"

Many thanks for helping.
While using SQLite dll Version 3.3.4 on Windows
- Multiple threads/processes access SQLite database,
- Each thread does some SELECTs, INSERTs or UPDATEs.
If for some single SELECT (where user input is used in SQL statement, so to
avoid SQL injection),
It depends upon your application. For it to function optimally you
should make each transaction on your application an SQL transaction,
commit it on success or rollback if there is a problem. In that way you
make each transaction atomic and maintain the integrity of your database.
