连接字符串你可以直接用字符串写,不用 ConnectionStringBuilder。默认的 SQLite 库是不支持密码的,所以老周就不设置密码了。在调用 AddSqlite 方法时,有一个名为 optionsAction 的参数,咱们可以用它配置日志输出。LogTo 方法配置简单,只要提供一个委托,它绑定的方法只要有一个 string 类型的输入参数就行,这个字符串...
Please, if you do, give the developers a working opportunity to opt out. I have an app which use sqlite-net and their defaulting to WAL in the connection constructor in the latest version completely broke my export data functionality, which relayed on the fact that all the data was in the...
Previous versions of the SQLite provider saved changes via a less efficient technique which was able to automatically retry when the table was locked/busy and write-ahead logging (WAL) was not enabled.New behaviorBy default, EF Core now saves changes via a more efficient technique, using the ...
"Filename=" + _connectionString : _connectionString; var conn = new SqliteConnection(connectionString); conn.Open(); // Enable write-ahead log var cmd = conn.CreateCommand(); cmd.CommandText = "PRAGMA journal_mode = 'wal'"; cmd.ExecuteNonQuery(); return conn; Stacktrace Exception Found:...

以前版本的 SQLite 提供程序通过效率较低的技术保存更改,该操作在表锁定/繁忙且未启用预写日志记录 (WAL) 时可自动重试。新行为默认情况下,EF Core 现在使用 RETURNING 子句通过更高效的技术保存更改。 遗憾的是,此方法在表忙碌/锁定时无法自动重试。 在不使用预写日志记录的多线程应用程序(如 Web 应用)中,通常...

read operations are completely isolated from write operations. No locking is required. But SQLite simply doesn't implement this behavior. It seems to me than Sqlite can support parallel readers when in WAL mode (see
