Or ATTACH DATABASE file::memory:

An SQLite database is normally stored in a single peculiar disk file. However, in certain circumstances, the database is perhaps saved in Memory Wave Method. The most common technique to force an SQLite database to exist purely in memory is to open the database utilizing the special filename ":memory:". 2() features, go in the string ":memory:". When this is finished, no disk file is opened. As an alternative, a new database is created purely in memory. The database ceases to exist as soon as the database connection is closed. Every :memory: database is distinct from every different. So, opening two database connections every with the filename ":memory:" will create two impartial in-memory databases. The special filename ":memory:" can be utilized anywhere that a database filename is permitted. Notice that in order for the special ":memory:" identify to use and to create a pure in-memory database, there must be no extra text within the filename. Thus, a disk-primarily based database can be created in a file by prepending a pathname, like this: "./:memory:".



The particular ":memory:" filename also works when utilizing URI filenames. In-memory databases are allowed to make use of shared cache if they're opened utilizing a URI filename. If the unadorned ":memory:" title is used to specify the in-memory database, then that database all the time has a personal cache and is barely seen to the database connection that initially opened it. Or, ATTACH DATABASE 'file::memory:? This allows separate database connections to share the same in-memory database. After all, all database connections sharing the in-memory database need to be in the same process. The database is robotically deleted and memory is reclaimed when the last connection to the database closes. Or, ATTACH DATABASE 'file:memdb1? When an in-memory database is named in this manner, it'll only share its cache with another connection that makes use of exactly the same name. ATTACH is an empty string, then a new momentary file is created to hold the database. A distinct temporary file is created each time in order that, simply as with the particular ":memory:" string, two database connections to temporary databases each have their very own non-public database. Short-term databases are robotically deleted when the connection that created them closes. Regardless that a disk file is allocated for each short-term database, in observe the momentary database normally resides within the in-memory pager cache and therefore there may be very little difference between a pure in-memory database created by ":Memory Wave:" and a short lived database created by an empty filename. The only real difference is that a ":memory:" database must stay in memory always whereas components of a short lived database is likely to be flushed to disk if the database turns into massive or if SQLite comes beneath memory pressure. The earlier paragraphs describe the conduct of temporary databases below the default SQLite configuration. Retailer compile-time parameter to power short-term databases to behave as pure in-memory databases, if desired.



Wait a minute: Disney owns both the Indiana Jones franchise and Marvel … Indiana Jones is part of the Marvel Cinematic Universe! In the same scene where the Red Skull makes an Indy reference, there’s a hint of what’s to are available Thor: Ragnarok. The Tesseract is saved in a wall sculpture of Yggdrasil, "the world tree," whereas the serpent is known as Jormungandr. Whereas fleeing the Hydra fortress in The primary Avenger, the Pink Skull’s right-hand man Dr. Arnim Zola could be seen quickly stuffing files right into a briefcase. In the event you look closely, you’ll discover that one of those recordsdata is in truth a blueprint for the robotic physique the character inhabits in the comics. However that’s not the only reference to Robo Zola … When Dr. Arnim Zola is first launched in The first Avenger, his face is distorted through a lens or screen of some sort. This is actually a reference to the character in the comics, as his thoughts inhabits a robot body, with his face displayed on a display on the robot’s torso.



While we don’t get to see Zola in all his robot glory in the sequel, The Winter Soldier, having his consciousness inside a pc is a pretty good payoff to this neat Easter egg. Although this scene doesn’t come from a Captain America film, it very properly could have been worked into The primary Avenger. On the home video release of The Unbelievable Hulk, there’s an alternate beginning that shows Bruce Banner walking through a snowy panorama. Eventually, an avalanche is triggered and while the snow falls towards the camera, you'll be able to just make out Captain America’s frozen physique buried in the ice. It’s very robust to spot, as it’s only there for a split-second, however it’s a cool detail that makes reference to a movie that wouldn’t come out for three years after The Unbelievable Hulk’s release. The peak dynamics of finest buds Steve Rogers (Chris Evans) and Bucky Barnes (Sebastian Stan) in The first Avenger are reasonably interesting.
