sqlite3_close(sqlite3*) This routine closes a database connection previously opened by a call to sqlite3_open().All prepared statements associated with the connection should be finalized prior to closing the connection.

SQLite3_exec() routine parses and executes every command given in the sql argument until it reaches the end of the string or encounters an error.Reading and writing files involves transferring a sequence of bytes between your code and the underlying disk.This is the lowest-level form of file management but is also the foundation for more sophisticated techniques as well.There are several different technologies for reading and writing the contents of files, nearly all of which are supported by both i OS and mac OS.All of them do essentially the same thing but in slightly different ways.If the filename argument is NULL or ':memory:', sqlite3_open() will create an in-memory database in RAM that lasts only for the duration of the session.

If the filename is not NULL, sqlite3_open() attempts to open the database file by using its value.At some point, even the most sophisticated data structures have to be turned into a sequence of bytes before they can be stored on disk.Similarly, that same data must be read from the disk as a sequence of bytes before it can be used to reconstruct the more sophisticated data structures that it represents.Lower-level technologies like POSIX and Grand Central Dispatch (GCD) give you maximum flexibility and power but require you to write a little more code.Because file operations involve accessing a disk (possibly one on a network server), performing those operations asynchronously is almost always preferred.If no file by that name exists, sqlite3_open() will open a new database file by that name.
