If I later programmatically log in to this database with a value of 10000 iterations, then the database will not open. I cannot set more than 10000, the application freezes if the value is large. Understand the layout of the DB Browser for SQLite and the key facilities that it provides. When I check an encrypted database using DB Browser, the program does not require changing the number of iterations, and the default value of 256000 is used. What does the DB Browser for SQLite allow me to do Objectives. QDebug() << "export failed: " << exportQuery.lastError().text() Īfter that I disable the encrypted database and close the normal database. To create a new table in SQLite, you use CREATE TABLE statement using the following syntax: CREATE TABLE IF NOT EXISTS schemaname. 51, /// For attach database there is no throw mode. If (!exportQuery.exec("SELECT sqlcipher_export('en') ")) auto databasepath validateSQLiteDatabasePath(path, userfilespath, needcheck, throwonerror). QSqlQuery exportQuery(QSqlDatabase::database(currentUser)) QDebug() << "attach failed: " << attachQuery.lastError().text() If (!attachQuery.exec("ATTACH DATABASE '" + dbPathNameEnc + "' AS en KEY '" + password + "' ")) QSqlQuery attachQuery(QSqlDatabase::database(currentUser)) QSqlQuery kdfquery(QSqlDatabase::database("en")) If(!encquery.exec("pragma key = '" + password +"' ")) QSqlQuery encquery(QSqlDatabase::database("en")) QSqlDatabase encryptedDb = QSqlDatabase::addDatabase("SQLITECIPHER", "en") ĮtDatabaseName(dbPathNameEnc) I have created an empty encrypted database and attached it to the plain database using the following code: QString dbPathNameEnc = "databases/en.db" Note: Please follow the steps in our documentation to enable e-mail notifications if you want to receive the related email notification for this thread.I am trying to export data from a plain SQLite database to an encrypted SQLCipher database with a specified number of KDF iterations. But the problem is that you can just drag and drop only one table at a time and therefore its not really a solution for this answer specifically but yet it can. Then try to open your databases in 2 windows and try merging them by simply drag and drop tables from one to another. If you have extra questions about this answer, please click "Comment". First try to download and install DB browser for sqlite database. If the answer is the right solution, please click "Accept Answer" and kindly upvote it. MessageBox.Show("You have opened the app 2 times, so you can not open it again") įinally, you could get the following result: Adding a field to an SQLite table with DB Browser for SQLite. SQLiteCommand sqlCom = new SQLiteCommand("Select * From Stuinfo", m_dbConnection) SQLiteConnection m_dbConnection = new SQLiteConnection("Data Source=Database2.sqlite") SQLiteDataAdapter adapter = new SQLiteDataAdapter(sqlCom) SQLiteCommand sqlCom = new SQLiteCommand("Select * From highscores", m_dbConnection) SQLiteConnection m_dbConnection = new SQLiteConnection("Data Source=Database1.sqlite") private void Form1_Load(object sender, EventArgs e) Second, here is a code example you could refer to. Durand, as others said, we could store the time value in ttings so that we can check if the app is opened at the first time or at the second time.įirst, we could set the following settings in your app.
