问题 The problem I've got a programm that uses storm 0.14 and it gives me this error on windows: sqlite3.OperationError: database table is locked The thing is, under linux it works correctly. I've got the impression that it happens only after a certain amount of changes have been done, as it happens in some code, that copies a lot of objects. Turning on the debug mode gives me this on windows: 83 EXECUTE: 'UPDATE regularorder_product SET discount=? WHERE regularorder_product.order_id = ? AND

问题 I've got a problem deploying a very simple example rails app on Heroku. This app uses a db. In local (OSX) with sqlite3 there is no problem, but I can't push to Heroku because some lost reference to sqlite3. I've put on Gemfile the distinction between test, development and production environments: #gem 'sqlite3' group :development, :test do gem 'sqlite3' end group :production do gem 'pg' end and bundle withou problem: bundle install --without production But when i deploy to Heroku: git push

问题 If I change environment variable using os.environ , do the modules I import afterwards see that change? Specifically, sqlite3 requires the use of an environment variable to determine its temporary file location. But if I use os.environ['SQLITE_TMPDIR'] = '.' before import sqlite3 , it does not have the desired effect. Why? 回答1: The sqlite3 module is just a wrapper for the SQLite C library, so it will not directly see any changes made to os.environ . However, the documentation says: If the

问题 I have a huge problem... I am developing desktop app with SQLite but during copy/paste process I lost a power and process was terminated so base was lost. However, I found a way to recover it but base is encrypted. When I try to open connection using conn.Open(); I get this error. If I try to open it with DB Browser for SQLite it asks me a SQLCipher encryption password so it seams to me that data is lost.. Is there any default password ? Why did this happen and how to prevent it from

问题 I'm using FMDB to work with sqlite and I'd prefer to avoid a dependency on SQLCipher. How can I simply leverage the DataProtection capability built into iOS? Is this possible - the only requirement is to protect the data in the event of the phone being stolen. If the phone is unlocked with a PIN, it's fine that the user could access the DB - it's their data. 回答1: Look for the line where you do databaseWithPath: (or initWithPath: ), then add: FMDatabase *db = [FMDatabase databaseWithPath:path]
