the ResultSet getter method.
In the Getter () method, if you are entering a column name to get a value, the column name is not case-sensitive. If the getter () gets a duplicate of the column name of the value, the last value returned is the first successful match. The general use of column names is when generating resultset through a database query statement. Database queries do not have to use column names, or they can be indexed by columns. It is also best to use the index of the column. If y

RPM is a package management method developed by Red Hat Company, we can easily install, inquire, uninstall and upgrade the software by using RPM. But the problem of dependency between RPM packages is often cumbersome, especially when software is made up of multiple RPM packages.

The Storage server provides storage services on a disk device. There are three types of storage servers in Swift: Account, container, and object. Where the container server handles the list of objects, the container server does not know where the object is stored, only what object is stored in the specified container. These object information is stored in the form of a SQLite database file. The container ser
