[sqlite] temp tables and PRAGMA temp_store
Using the latest SQLite and trying to speed up the making of some intermediate tables. I thought I could do that by doing PRAGMA temp_store = MEMORY and CREATE TEMP TABLE etc. I do run the PRAGMA directly after establishing the SQLite connection. So far I haven't seen any speed increase yet and I am wondering if maybe I am doing something wrong here. Does this PRAGMA only work on a newly created db file? Have tried that, but again no difference. Would you expect a speed increase from doing the above? I am running this from VB with the wrapper from Olaf Schmidt. Thanks for any advice.

[sqlite] In memory data base questions ???
Hi, I am planning to use only in-memory data base for my application. I have couple of questions? 1) Would SQLite still make Rollback Journal files? If yes can it be turned off with pragma, etc.? 2) If I have a single in-memory connection with multiple statements, should I worry about table locks?

[sqlite] SQLite full text speed
I'm curious about the speed trade off between a full table scan and just a flat file search... Say I have a database with 2 records in it. If I do a query like: SELECT foo FROM table WHERE bar LIKE '%glaven%'; That will be a full text scan across the table. Would that be any faster than just a regexp against a flat text file? Obviously you get the advantages of SQL were it in a DB, versus a flat file. What other trade offs are there?

How big is the value of bar? Of course, in SQLite there is no column width concept, so one could stuff in a 10,000 words novel in a column of a row and drastically change the result. That said, my sense is that probably grep against a 20K word file would be faster than SQLite, but again, I am pulling that sense out of thin air. I am too lazy to find a 20K file, grep against it for a pattern, then make a table out of it, and SQL search against it using SQLite.

Alex Katebi [EMAIL PROTECTED] wrote: So are you telling me that if a statement has started a select on a table with a delayed finalize another statement can update the same table? Yes, as of recent enough SQLite version. I'm kind of skeptical myself, but Dr. Hipp insists this is possible and safe. I haven't personally worked up the courage to use this feature though. I do update one table while scrolling through another - that works. The reason I ask this question is that in my application a user can start a query and take his time before he ends it. Meanwhile the same table needs to be updated by my application. Can you tell be why there would be no lock contention? There is a lock (not the file-level database lock, but the OS mutex) during the call to sqlite3_step. But other than that, there's no contention. In other words, your update statement may have to wait while the select retrieves the next row, but it won't have to wait until you retrieve the complete recordset. Of course, there is no transaction isolation between the two statements, you are in dirty read mode. E.g., sufficiently complex SQL statemets may need to read the same row of the same table more than once: it is possible that one such read would see the original data and the other modified data. The recordset thus produced might be, shall we say, interesting. Igor Tandetnik ___ sqlite-users mailing list sqlite-users@sqlite.org http://sqlite.org:8080/cgi-bin/mailman/listinfo/sqlite-users

[sqlite] Bindings problem
Hi
I'm new to Sqlite and Python and have hit a snag.
I have a function that receives a single parameter record that
contains the contents for the column testdata
The program fails with the message:
Incorrect number of bindings supplied. The current statement uses 0,
and there are 10 supplied
There are 10 chars in the string variable that gets passed...it looks
like the code sees each char in the string as a separate binding?
The source is as follows:
def updateDb(record):
c.execute('INSERT INTO ardrecords (testdata) VALUES (?)', (record))
Thanks for the help.

Short answer: You should not be quoting the ? and are missing a comma
after record.
Long answer: Quoting the question mark inserts a question mark and is
not a binding. Also SQL uses single quotes as standard for strings with
double quotes resulting in implementation specific behaviour. (record)
is the same as record - to make it a sequence of the string you need to
use (record,). The final result should be:

Re: [sqlite] Hello I am a newbie : for SQLite : Create db : VB6
Hello. I happened to see this thread (I'm EzTools suppport). The Sqlite open function automatically creates a new file if the file doens't exist. SqlitePlus does the same thing (since it just passes through to Sqlite). However, I have added an additional, optional parameter that will cause the SqliteDb.Open method to fail if the file doesn't exist. But it is false by default, so calling open with a filename that doesn't exist should create the file. Maybe its being created in a different folder than your .exe? Its possible its in a place you don't expect if you aren't passing a full path. Anyway, here is a good way to call SqliteDb.Open from a VB app: db.Open App.Path my_database.db, 0, false Let me know via my eddress if you still have problems ([EMAIL PROTECTED]). cheers -brett Quoting palmer ristevski [EMAIL PROTECTED]: That is Great OLAF That is all that I am looking for.
