The synchronous pragma gets or sets the current disk synchronization mode, which controls how aggressively SQLite will write data all the way out to physical storage. Following is the simple syntax. PRAGMA [database.] synchronous; PRAGMA [database.]
PRAGMA foreign_keys = boolean; Query, set, or clear the enforcement of foreign key constraints. This pragma is a no-op within a transaction; foreign key constraint enforcement may only be enabled or disabled when there is no pending BEGIN or SAVEPOINT.
You can synchronize SQLite databases by embedding SymmetricDS in your application. It supports occasionally connected clients, so it will capture changes and sync them when a server comes online. It supports several different database platforms and can be used as a library or as a standalone service.
PRAGMA integrity_check behaves like a SELECT query that returns results in a single row. To read the results with sqlite3_exec , you need to use a callback. Please note that PRAGMA integrity_check is not guaranteed to find all errors, so you can use it only to check for broken databases, not for healthy databases.
I need a very fast SQLite database acces. Setting parameters this way:
PRAGMA synchronize = OFF
PRAGMA jorunal_mode = MEMORY
makes the speed to be enough for my project. These settings makes SQLite to leave synchronization with database file in the hands of operating system. But there are a few cases, some certain inserts, after which I must be sure that the data was written to the disk.
Is there any way I can force SQLite to write all data (waiting in memory journal) to disk?
Thanks.
