Calling UPPER() for each field/value while querying is a pain, if you can
assume the names are all in uppercase
(forcing this in your program before passing them to SQlite), you could
speed up things a lot. But you need to
analyze what´s happening inside SQlite to check if indices are used, etc.
I am on Window 7, opening an existing database with these flags:
SQLITE_OPEN_EXCLUSIVE |
SQLITE_OPEN_READWRITE |
SQLITE_OPEN_CREATE
Then I get a value from one table, begin a transaction, create a temp
customer table, fill it with the current values from the customer table.
Here is that SQL run

Unless your script language includes a SQL parser, that does not do what you

Thank you very much for your help! Now I've joined the tables using the
"join" query.
I think I need to create the new table

I have just joined this mailing list, because searching the archives I
have not found much related to locking. I am not completely new to
SQLite, having previously used it when I wrote my latest version of a
chat program, where I migrated the database over to from mysql.

Thanks for your reply. Before I try to understand your post, because you are
here now and maybe not later:
I will take the result (of 50.000 + lines), and further filter it to 5.000 +
lines, and then split that into 13 tables of 400+ lines, which I'll be
manipulating in excel, and print out to

So that when you're done, you have 3 tables "Chinese," "English," "Merged"
or the original 2, but with data from the one into the other.
I don't know the terms or the procedure, but I'd like to have a new table
that has the Chinese and English mixed, which I then can

One of SQLite's primary goals in life is to fit into a tiny memory
footprint.
Yes, please do send it to me.

Okay, so now I've gotten a bit further, but:
-- One table is more than 30.000 lines, the other is more than 50.000 lines.
I've understood from the video tutorial that the program (I'm using
http://www.sqlite.org/sqlite-3_6_23_1.zip) will first compile the entire
list 30.000 x 50.000 = 1.5
Thanks for your reply!

Hi Chris,
I had attached the source code but it mysteriously vanished. I'm guessing

Thanks Monte for your response.
I am still pretty new to SQlite, but it looks very similar to what Simon
suggested.
I think it would work just as well.
From my perspective the ideal way to do this would be to specify the columns
names the following data in the file is to load into.

Another method would be to add a column to the English table, and in that
insert the Chinese character that corresponds with the number in "Chinese
Char. No."

Hi,
I'm a noobie. I would have liked to first search this forum, but I don't
even know the search terms I should use ...
I'm using the firefox plugin "Sqlite Manager" to manipulate the data.
Question:
I have two tables:
TABLE 1:
Chinese Char. No. Chinese Char.

Just because I was bored ;) I decided to take a stab at this one as well
(following Simon's excellent guidance).
I had thought because of what it says in the FAQ here:

that it should be possible to import the values directly into the final table
and have sqlite
Hey guys.
I have a query which is very slow, and was wondering if there was any
advice you guys had on it.
Here are two table definitions:

AUTOINCREMENT, name TEXT NOT NULL UNIQUE, ranking TEXT, score REAL,
record TEXT);
