I am writing a test program with Ruby and ActiveRecord, and it reads a document which is like 6000 words long. And then I just tally up the words by recordWord = Word.find_by_s(word); if (recordWord.nil?) recordWord = Word.new recordWord.s = word end if recordWord.count.nil? recordWord.count = 1 else recordWord.count += 1 end r...
I am using the nested set model to store a large hierarchy of data in a local SQLite database on an iPhone. I read the MySQL tech article from their web site on how to do this, but one of the queries they suggest (and that I need) doesn't appear to work with SQLite and I'm not sure how to get around it. SELECT node.name, (COUNT(parent.n...
Hi, What is the type for a BOOL value in SQLite? I want to store in my table TRUE/FALSE values. I could create a column of INTEGER and store in it values 0 or 1, but it won't be the best way to implement BOOL type. Is there a way? Thanks. ...
I have some relatively complex sqlite queries running in my iPhone app, and some are taking way too much time (upwards of 15 seconds). There are only 430 or so records in the database. One thing I've noticed is that opening a new database connection (which I only do once) and stepping through query results (with sqlite3_step()) causes sq...
Hi, I want to choose a row from a certain table and order the results basing on another table. Here are my tables: lang1_words: word_id - word statuses: word_id - status In each table word_id corresponds to a value in another table. Here is my query: SELECT statuses.word_id FROM statuses, lang1_words WHERE statuses.status >= 0 OR...
I have a list of strings to insert into a db. They MUST be unique. When i insert i would like their ID (to use as a foreign key in another table) so i use last_insert_rowid. I get 2 problems. If i use replace, their id (INTEGER PRIMARY KEY) updates which breaks my db (entries point to nonexistent IDs) If i use ignore, rowid is not upda...

I have a sqlite table that was originally created with: PRIMARY KEY (`column`); I now need to remove that primary key and create a new one. Creating a new one is easy, but removing the original seems to be the hard part. If I do .indices tablename I don't get the primary key. Some programs show the primary key as Indexes: 1...
Is it possible somehow to create in-memory database in SQLite and then destroy it just by some query? I need to do this for unit testing my db layer. So far I've only worked by creating normal SQLite db file and delete if after all tests, but doing it all in memory would be much better. So is it possible to instanciate database only i...
