Hello, IF you need to do that just to setup your database once, then you can use any of free tools as suggested. Or you can simply run a SQLCommand through your code to drop and recreate a table using Standard SQL Create Table statement. Alter query will work to drop and add column as well.

In the other direction, if you have GetLastRecord(set_of_records) function defined somehow, then you can pick the last record, remove it from the set, pick the last of the remaining, remove that one from the set, and so on.

Re: [sqlite] Last record in db
According to the docs rowid is not guaranteed to be monotonic. So this is not guaranteed to give the right answer. SELECT ... ORDER BY rowid DESC LIMIT 1 However, define your own autoincrement (myid) and it is. SELECT ... ORDER BY myid DESC LIMIT 1 Michael D.

[sqlite] Bug in GCC - suggestions sought for a backup tool chain
Consider this line of code in the build.c source file of SQLite:
http://www.sqlite.org/src/artifact/77be7c217430?ln=3372
It appears that GCC 4.1.0 is not generating any code for the second test in
the conditional. In other words, GCC 4.1.0 is compiling that statement as
if it omitted the p-a term and looked like this:
if( p ){
You can see this for yourself by downloading the file above and then
running:
gcc -g -S build.c
And then looking at the build.s output file. With GCC 4.1.0, I get this:
.loc 1 3372 0
cmpl$0, 8(%ebp)
je.L920
Looks like only one test to me. But with GCC 4.5.2 I get this:
.loc 1 3372 0
cmpq$0, -24(%rbp)
je.L611
.loc 1 3372 0 is_stmt 0 discriminator 1
movq-24(%rbp), %rax
addq$8, %rax
testq%rax, %rax
je.L611
Both tests appear to be coded this time.
As it happens, the GCC bug is harmless in this case. SQLite never invokes
the sqlite3SrcListShiftJoinType() function with a non-NULL SrcList pointer
that has a NULL p-a value. So the p-a!=NULL test really is always true.
(Note that the GCC optimizer has no way of knowing that because the function
has external linkage.) And so it didn't matter that the test was omitted.
I didn't notice the problem until this morning, when I upgraded my desktop
to the latest Ubuntu containing GCC 4.5.2, and reran the full branch
coverage tests. GCC 4.5.2 was showing that the p-a!=NULL branch was always
true. Further investigation shows that it has always been always true but
that the GCC 4.1.0 bug simply masked the error up until now.
I see two take-aways from this episode:
(1) Compilers sometimes make mistakes. So it is important that you test
your object code - not just your source code. That means running your test
cases using exactly the same *.o files that you use for delivery. Fly what
you test and test what you fly.
(2) I need to come up with a second, independent method of verifying branch
test coverage in SQLite. I have been using GCC+GCOV and it does a great job
and I fully intend to continue using it as the primary tool chain for
development and testing. But in this case, because GCC was omitting a test,
it missed the fact that there was no test coverage for the omitted test. So
it would be nice to have an independently developed tool chain that can be
used to confirm the results we get from GCOV. Anybody have any suggestions?

There's no contradiction. Last is still defined only for ordered sets - you just chose a particular ordering, by rowid. And even if you do that, it's easy to break the expected ordering: .schema t1 CREATE TABLE t1(id INT,data TEXT); select * from t1 ; id data -- -- 1 one 2 two 3 tre delete from t1 where data = 'two'; insert into t1 (it, data) values (2, 'second'); Now the 'last' record is not the one with the highest value in the id column. Igor is right. The question from the original poster doesn't mean anything in SQL. SQL has no concept of an order for rows, so it has no idea which row is 'first' or 'last'. If you, the programmer have your own idea what is first or last, write your own numbers into the database.

[sqlite] Split Function for SQLite?
I need to split up a list of items in a single row so they each have their own row. Basically I need to take this: Key. Code -- 1. V1, v2, v3 And convert it to this: Key. Code -- 1. V1 1. V2 1. V3 After much googling I'm thinking I need a split function. I know SQLite allows addition of functions. I did find a few different implementations of split functions, but there were from full SQL and SQL Server sites. Do I need a split function designed specifically for SQLite? How would I go about adding the function so I can use it? Thanks!
