SQLite 3.45 er blevet frigivet, en letv\u00e6gts DBMS, der er designet som et plug-in bibliotek. Koden til SQLite er offentlig ejendom, hvilket betyder, at den kan bruges uden begr\u00e6nsninger og gratis til enhver form\u00e5l. Den finansielle st\u00f8tte til SQLite-udviklerne gives af et s\u00e6rligt konsortium, der inkluderer virksomheder som Bentley, Bloomberg, Expensify og Navigation Data Standard. <\/p>\n
Vigtige \u00e6ndringer: <\/p>\n
Yderligere kan udviklingen i de eksperimentelle byggeversioner af SQLite fremh\u00e6ves med en ny transaktionsjournaliseringsmetode \u2014 WAL2 («PRAGMA journal_mode = wal2»), hvor der bruges to wal-filer («database-wal» og «database-wal2») i stedet for \u00e9n. N\u00e5r data skrives til databasen, tilf\u00f8jes nye data til den f\u00f8rste wal-fil. Hvis den f\u00f8rste wal-fil n\u00e5r en tilstr\u00e6kkelig stor st\u00f8rrelse, skiftes der til skrivning i den anden fil. Efter skift til den anden wal-fil bliver den f\u00f8rste tilg\u00e6ngelig for fasts\u00e6ttelse af \u00e6ndringer (checkpoint) og overskrivning. Tilsvarende, n\u00e5r den anden wal-fil n\u00e5r en stor st\u00f8rrelse, skiftes der tilbage til den f\u00f8rste osv., hvilket l\u00f8ser problemet med ukontrolleret v\u00e6kst af wal-filen i situationer, hvor transaktionen ikke fasts\u00e6ttes i lang tid, eller der udf\u00f8res lange l\u00e6seprocesser. \u041e\u043f\u0443\u0431\u043b\u0438\u043a\u043e\u0432\u0430\u043d \u0440\u0435\u043b\u0438\u0437 SQLite 3.45, \u043b\u0435\u0433\u043a\u043e\u0432\u0435\u0441\u043d\u043e\u0439 \u0421\u0423\u0411\u0414, \u043e\u0444\u043e\u0440\u043c\u043b\u0435\u043d\u043d\u043e\u0439 \u0432 \u0432\u0438\u0434\u0435 \u043f\u043e\u0434\u043a\u043b\u044e\u0447\u0430\u0435\u043c\u043e\u0439 \u0431\u0438\u0431\u043b\u0438\u043e\u0442\u0435\u043a\u0438. \u041a\u043e\u0434 SQLite \u0440\u0430\u0441\u043f\u0440\u043e\u0441\u0442\u0440\u0430\u043d\u044f\u0435\u0442\u0441\u044f \u043a\u0430\u043a \u043e\u0431\u0449\u0435\u0441\u0442\u0432\u0435\u043d\u043d\u043e\u0435 \u0434\u043e\u0441\u0442\u043e\u044f\u043d\u0438\u0435 (public domain), \u0442.\u0435. \u043c\u043e\u0436\u0435\u0442 \u0438\u0441\u043f\u043e\u043b\u044c\u0437\u043e\u0432\u0430\u0442\u044c\u0441\u044f \u0431\u0435\u0437 \u043e\u0433\u0440\u0430\u043d\u0438\u0447\u0435\u043d\u0438\u0439 \u0438 \u0431\u0435\u0437\u0432\u043e\u0437\u043c\u0435\u0437\u0434\u043d\u043e \u0432 \u043b\u044e\u0431\u044b\u0445 \u0446\u0435\u043b\u044f\u0445. \u0424\u0438\u043d\u0430\u043d\u0441\u043e\u0432\u0443\u044e \u043f\u043e\u0434\u0434\u0435\u0440\u0436\u043a\u0443 \u0440\u0430\u0437\u0440\u0430\u0431\u043e\u0442\u0447\u0438\u043a\u043e\u0432 SQLite \u043e\u0441\u0443\u0449\u0435\u0441\u0442\u0432\u043b\u044f\u0435\u0442 \u0441\u043f\u0435\u0446\u0438\u0430\u043b\u044c\u043d\u043e \u0441\u043e\u0437\u0434\u0430\u043d\u043d\u044b\u0439 \u043a\u043e\u043d\u0441\u043e\u0440\u0446\u0438\u0443\u043c, \u0432 \u043a\u043e\u0442\u043e\u0440\u044b\u0439 \u0432\u0445\u043e\u0434\u044f\u0442 \u0442\u0430\u043a\u0438\u0435 \u043a\u043e\u043c\u043f\u0430\u043d\u0438\u0438, \u043a\u0430\u043a Bentley, Bloomberg, Expensify \u0438 Navigation Data Standard. \u041e\u0441\u043d\u043e\u0432\u043d\u044b\u0435 \u0438\u0437\u043c\u0435\u043d\u0435\u043d\u0438\u044f: \u0412\u0441\u0435 SQL-\u0444\u0443\u043d\u043a\u0446\u0438\u0438 \u0434\u043b\u044f […]<\/p>\n","protected":false,"gt_translate_keys":[{"key":"rendered","format":"html"}]},"author":1,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[702],"tags":[],"class_list":["post-113031","post","type-post","status-publish","format-standard","hentry","category-news"],"aioseo_notices":[],"aioseo_head":"\n\t\t\n\t\n\t\n\t\n\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\n","aioseo_head_json":{"title":"\ud83e\udd47Udgivelse af DBMS SQLite 3.45 | ProHoster","description":"SQLite 3.45 er blevet udgivet, en letv\u00e6gts DBMS, der er udformet som et plug-in bibliotek.
