I use the SQLiteDump.Restore method to restore my sqlite db. First I read in the backupscript into an streamreader, then call Restore (in an transaction). The backupscript includes ca 5000 insert statements to diffrent tables. But the operation is very,very slow. 10-15 minutes. Is there any other solution to backup and restore an sqlite database?

My code:

Code: Select all

var streamReader = new StreamReader(pRestoreFilePath, Encoding.UTF8);  
                if (mSqLiteConnection.State != ConnectionState.Open)
                   mSqLiteConnection.Open();

                var sqSqlDump = new SQLiteDump {Connection = mSqLiteConnection};
                SQLiteTransaction transaction = mSqLiteConnection.BeginTransaction(IsolationLevel.ReadCommitted);

                
                sqSqlDump.Restore(streamReader);
                transaction.Commit();

I have checked the 3.10.121 version of dotConnect for SQL using the code that I have just sent to your e-mail address. Here is my output:
Table is populated with 5000 rows in 00:00:00.1493707
Backup is created in 00:00:00.0614540
Table is restored in 00:00:00.2384974

Please give us the following:
1) the exact version (x.xx.xxx) of your dotConnect for SQLite. You can find it in the Tools > SQLite > About menu of Visual Studio;
2) the target framework of your project;
3) modify and send our code back to us to reproduce the problem in our environment. If necessary, attach your database.
