Re: [sqlite] Is there a difference between DELETE and UPDATE/INSERT in terms of syncing to disk?
For the record, the problem was that django (by default) starts a transaction before handing an http request, then commits it after the request is handled. Since we were in the middle of a transaction, all the python/django code we wrote saw the state of the DB as it was partially through a transaction, but external code didn't see the changes on disk yet. We didn't realize that we were opertaing within an uncommitted transaction, so had a the race condition where we kicked off an external process to backup the DB after the DELETE was complete, and it would sometimes see the changes, and sometimes not, depending on what happened first - the request handler completing and transaction getting committed, or the external process starting up and locking the DB. I think there is something specific about the relative speeds of the handlers that do DELETEs vs. INSERTs that biased the race condition, so who won depended on the action and led us down the wrong path. Anyhow, thanks for your help. Cheers, Sam ___ sqlite-users mailing list sqlite-users@sqlite.org http://sqlite.org:8080/cgi-bin/mailman/listinfo/sqlite-users

Next I would fire up the CLI (type "sqlite3.exe mydb.db" at the command prompt if you're using Windows, assuming your database is named mydb.db), then type ".import docdata.csv mytable" or whatever your csv file and target table are named (type ".help" for further info).

*If* you can manage a reasonable export to .csv (using Excel, if needed, or not), then, yes, that would be a way to go IMHO. Lookup the .import command in the CLI (command line interface).

Your friend could as well print this file and send you the printer output, essentially that would make no difference. A .doc file is basically a load of printer instructions, but generally it doesn't hold any structured data. The latter, however, is what a database needs and is made for. Depending on how this specific .doc file (and your database) looks like, there *may* be some things one could try, but they are all very time consuming and require programming skills. >Is there a magic command No. Neither in SQLite, nor in any other database system.

Hi, At the beginning I will say that I am not a specialist in databases. I have the following problem to figure out: I have a database (sqlite). In it, about 8800 records (lyrics) I have received from a friend list (selected about 800 songs), but unfortunately send me a .doc file Is there a magic command in sqlite that will help me to choose automatically with a whole database identified 800 songs? If so, what commands should I use?

[sqlite] sqlite3 amalgamation and unused variables
There seem to be a couple of variables in the sqlite3 amalgamation that get assigned a value but actually their value is not used. If there is an intention to get rid of these statements I will submit samples like h = pFile->h; (sqlite3.c in line 26039 version 3.7.7) But perhaps these lines originate from merging source code files into the amalgamation file?!

APIs themselves don't really represent much bulk. You'll notice that many of the APIs are small variations on a theme (like the "bind" functions), making the numbers add up quickly. That said, there are some functional areas that take up some bulk, and may not be required for your situation. Many of these can be compiled out using the "OMIT" build directives: http://www.sqlite.org/compile.html#omitfeatures Just be sure you read the notes carefully... mainly that the OMIT defines are designed to be used against the canonical source code. That means building from the source tree, including the parser code. Also note that none of the OMIT flags are officially supported, none of them are tested, and, for any given version of the source code, various combos of OMIT defines are likely to break things. If you're using an extensive number of OMIT flags, a bit of code clean-up may be required. -j -- Jay A.

SQLite is distributed as source code. It's available in two forms: either lots of individual files each with their own subject area, or as one big 'amalgamation' C file. You can download both from http://www.sqlite.org/download.html Pick one form. Download it. Compile it and check that it compiles in your compiler and runs as supplied. Remove everything you don't think you need. Compile as suits you. Fix dependencies and try again.

[sqlite] Minimal SQLite
Hi All, I want to use SQLite for one of the application which runs on a embedded system where we have memory limitations. In the SQLite we have around 180+ distinct APIs, but not all APIs we are going to use it. What I want is the just core APIs. Can I build SQLite in such a way that I can avoid all the unnecessary API implement ions in the final library. I want to avoid all the extra APIs except the core API. If any compiler setting can help to achieve will be great. Any hint to achieve it, is also really appreciated.
