// assume the variable named "sql" is a string containing a SQL statement PreparedStatement* pstmt = conn->prepareStatement(sql); // set the 8-bit unsigned integer value to 255 pstmt->setUInt8(1, 255); // execute the SQL statement pstmt->execute();This code sets the value of the first parameter in the prepared statement to 255 using the setUInt8 method. The preparedStatement instance is then executed to perform the action as specified by the SQL statement. The package library that provides the PreparedStatement class depends on the specific database driver being used. For example, the MySQL Connector/C++ library provides a PreparedStatement class that can be used to prepare SQL statements when interacting with MySQL databases. Similarly, other database libraries such as SQLite, PostgreSQL or Oracle also provide PreparedStatement implementations that can be used in C++ code.
