Re: [sqlite] sqlite with FORTRAN
I added to the wiki (http://www.sqlite.org/cvstrac/wiki?p=SqliteWrappers) an entry for Fortran. It links to a page on my web site, http://danial.org/sqlite/fortran/, that has an example of a Fortran program that calls C wrapper functions which in turn call functions in the SQLite library. The demo creates a database, inserts values into a table, then does a query. It builds with g77 and gcc. -- Al On 7/8/05, Cornel Gazdaru <[EMAIL PROTECTED]> wrote: > Hi > I am trying to figure out a wrapper to access sqlite from FORTRAN (g77 > and gcc) > I try using "cfrotran.h" but it seems I have problems passing arguments. > Not sure I get the sqlite3 handle correctly > Has anybody tried that before? > Thanks > Cornel > >

"Monotonically increasing" does not mean that for every key k there will be a key (k-1). In fact, if you ever delete a row in an autoincrement table, you're guaranteed to have a "hole" in your keys. You don't really need a manufactured key. Since your arithmetic depends on the timestamp being unique, you can use the timestamp as your primary key; but you should define the key to enforce existence and uniqueness: create table bytes (ts int primary key, bytes int); insert into bytes (ts, bytes) values (1121484797, 11234); insert into bytes (ts, bytes) values (1121484923, 14583); insert into bytes (ts, bytes) values (1121485008, 19267); insert into bytes (ts, bytes) values (1121484801, 12789); insert into bytes (ts, bytes) values (1121485051, 23005); insert into bytes (ts, bytes) values (1121485832, 28436); select datetime(ts, 'unixepoch'), bytes from bytes order by ts; || \/ datetime(ts, 'unixepoch') bytes - -- 2005-07-16 03:33:1711234 2005-07-16 03:33:2112789 2005-07-16 03:35:2314583 2005-07-16 03:36:4819267 2005-07-16 03:37:3123005 2005-07-16 03:50:3228436 select datetime(ts, 'unixepoch'), bytes from bytes where datetime(ts, 'unixepoch') between '2005-07-16 03:35:01' and '2005-07-16 03:40:00' order by ts; || \/ datetime(ts, 'unixepoch') bytes - -- 2005-07-16 03:35:2314583 2005-07-16 03:36:4819267 2005-07-16 03:37:3123005 select datetime(t2.ts, 'unixepoch') 'time', (0.0+t2.bytes-t1.bytes)/(t2.ts-t1.ts) 'byte rate' from bytes t1, bytes t2 where t1.ts = (select max(t3.ts) from bytes t3 where t3.ts < t2.ts) and datetime(t2.ts, 'unixepoch') between '2005-07-16 03:35:01' and '2005-07-16 03:40:00' order by t2.ts ; || \/ time byte rate --- 2005-07-16 03:35:23 14.7049180327869 2005-07-16 03:36:48 55.1058823529412 2005-07-16 03:37:31 86.9302325581395 But SQL is not designed to do sequential processing of data.

sure thing. We were at

foo;qux|barr
after that I did the following...

sqlite> select * from t;
foo;qux|barr
qux|baz
sqlite> update t set a = 'foo;bar', b = 'barr' where b = 'barr';

First off, the quickstart doesn't specify that you need to include the source (just the external interface header).

I even removed the tcl*.c files and still got the errors. I'm compiling in Visual C++ 7.1. Also, I tried to build with the *.dll but the *.dll file doesn't come with a header for it or static *.lib to link against. If I use the *.dll do I have to fn* every function I wish to use? Lee, You need to use the LIB command line utility that comes with VC++ to generate an sqlite3.lib file which will let you use the sqlite3.dll library. You need to feed the sqlite3.def file into the LIB utility and it will generate an sqlite3.lib which you can link with your project. The following command is used in the Makefile. lib /machine:i386 /def:sqlite3.def HTH Dennis Cote
