/**
* @brief Return the type of the value of the column
* @brief Return the type of the value of the column using sqlite3_column_type()
*
* Return either SQLite::INTEGER, SQLite::FLOAT, SQLite::TEXT, SQLite::BLOB, or SQLite::Null.
* This type may change from one row to the next, since
* SQLite stores data types dynamically for each value and not per column.
* Use Statement::getColumnDeclaredType() to retrieve the declared column type from a SELECT statement.
*
* @warning After a type conversion (by a call to a getXxx on a Column of a Yyy type),
* the value returned by sqlite3_column_type() is undefined.
