HOW TO CREATE SQLITE DATABASE IN ANDROID STEP BY STEP CODE

You can find the whole source code on my github. To remove all persons, just run: QSqlQuery query Query.prepare('SELECT name FROM people WHERE name = (:name)') QString name = query.value(idName).toString() Д¬heck if person with specific name exists: QSqlQuery query Int idName = query.record().indexOf('name') Print all persons: QSqlQuery query('SELECT * FROM people') Query.prepare('DELETE FROM people WHERE name = (:name)') Rules of creating queries are simple, so I think you already know how removing person looks like: if (personExists(name)) QSqlQuery::lastError() is very useful, you should not skip it in your implementation. Query.prepare('INSERT INTO people (name) VALUES (:name)') you should check if args are ok first. bool DbManager::addPerson(const QString& name) After prepare call bindValue to fill the placeholders with proper values. QDebug() << 'Error: connection with database fail' ДЇor managing people resources we need the possibility to:ДЄctions can be implemented in following way: define QSqlQuery, then call prepare method - it can be raw SQL query string, or it can contain placeholders for variables - placeholders must begin with colon. M_db = QSqlDatabase::addDatabase('QSQLITE') DbManager::DbManager(const QString& path) The path argument value is the path to your database file. The constructor of DbManager sets up the database connection and opens it. Now you can create a class responsible for database access. In the Additional Dependencies add Qt5Sqld.lib for Debug and Qt5Sql.lib for release. In VS linker settings is located in Properties/Configuration properties/Linker/Input.

You need to do it if your compilation fails with unresolved external symbol error. If you donвЂ™t use QtCreator but another IDE, for example Visual Studio, your project may need setting linker dependency to QtSql.lib. It will link your project against QtSql module. Access database from Qt applicationД¬reate new Qt project. Now we can create C++ application to play with it. Sqlite> CREATE TABLE people(ids integer primary key, name text) Д¬ongrats, your database is ready. To leave the sqlite console just type вЂњ.quitвЂќ. It cointains a key (integer) and name (text).

With sqlite you can create such a simple database with two console commands. LetвЂ™s assume, for simplicity, that we need to store people data - only name and corresponding id. Read more about sql driversвЂ¦ Design and create the database

Error should be followed by a console output that informs you which drivers you have installed: вЂњQSqlDatabase: available drivers:вЂќ.

If you face problems like вЂњQSqlDatabase: QSQLITE driver not loadedвЂќ you need to install drivers manually. Depending on your distribution, you can have the drivers installed by default with your Qt or not. Qt requires drivers to deal with SQL databases. I have chosen SQLite engine because itвЂ™s the easiest engine to set up (it requires no server, no configurationвЂ¦), still itвЂ™s suitable for the most of possible applications. Here is some short example that presents how to do it. Accessing SQL databases from C++ applications is very simple with Qt library.
