Notes on truncate table

Notes on truncate table --- The following is a summary of the quotations of itpub's predecessors. After truncate table, oracle recycles the index of the table and its table to the initial size, that is, the size of the initial allocated segments.Truncate and drop are both ddl statements, and the operation takes effect immediately. The original data is not stored in rollback segment and cannot be rolled back. Truncate table execution is slow for the following reasons:First, you must understand t

pinyin characters, and 6400 word-building areas, 20249 retained, totaling 65534. The size after unicode encoding is the same. For example, if an English letter "a" and a Chinese character "good" is used, the occupied space after encoding is the same, both of which are two bytes! Unicode can be used to indicate characters in all languages, and is a fixed-length dual-byte (also four-byte) encoding, including English letters. So it can be said that it

, it is only 29.8 astronomical units from the sun, closer than Neptune. The orbital angle is 17.1 °, which is much larger than other major stars. The average orbital speed is 4.74 km/second, and it takes 248 to go public for a week. Based on the variation in the brightness of Pluto's surface, it can be measured that its rotation cycle is 6 days, 9 hours, 17 minutes. The angle between the self axis and the Public axis of Pluto is greater than 60 °, so it is similar to the lateral rotation of Uran
