The columns can be indexed by numbers in the order they are given inside the result set starting from 1. The actual data is obtained through the getXxxx() functions such as getInt(), getString(), etc. Otherwise it returns false, which means we reached the end of the result set and there are no more rows to read.

The code below walks through the entire result set row by row using sql::ResultSet::next() method, which returns true if the row was successfully read. By default, Connector/C++ buffers all result sets on the client to support cursors.
#Mysql jdbc code driver
Download JDBC driver for MySQL First, in order to have Java program working with MySQL, we need a JDBC driver for MySQL. Java code example connects to MySQL database. Understand the getConnection() method of DriverManager class. Both methods return sql::ResultSet objects. No need to load MySQL driver class explicitly. If your query returns one result set, use sql::Statement::executeQuery() or sql::PreparedStatement::executeQuery() to run your query. The API for fetching result sets is identical for (simple) statements and prepared statements.

Therefore we use std::unique_ptr to free memory when they are not needed anymore. Please add below maven dependency to your project’s pom.xml file.Res(stmt->executeQuery( "SELECT 'Welcome to Connector/C++' AS _message")) Note The Statement and ResultSet objects are temporary, but they are dynamically allocated. Step - 3: We will read all records one by one and print it on Eclipse Console.
Step - 2: We will add 3 records to Database.In case of JDBC failure, we will throw an error message Driver db.myotherdb.url jdbc:mysql:///NameOfOtherDBcharacterEncodingUTF-8 db.er. Perform executeQuery() operation to retrieve data from MySQL Table.The JDBC specification is flexible on how certain functionality should be implemented. Perform executeUpdate() operation to insert data into Table MySQL Connector/J, as a rigorous implementation of the JDBC API, passes all of the tests in the publicly available version of Oracles JDBC compliance test suite.Create standard DB Connection, PreparedStatement and ResultSet Objects.If your purpose is just for study, you can download XAMPP for using MySQL DB.
