The sorting is divided into two kinds, one sort in situ, the other is the copy sort>>> data = [1,4,2,8,9,5,6,0]>>> Data.sort ()>>>>>> data[0, 1, 2, 4, 5, 6, 8, 9]>>> data = [4,66,7,2,7,9,0,5,]>>> data2 = sorted (data)>>>>>> data2[0, 2, 4, 5, 7, 7, 9, 66]>>> data[4, 66, 7, 2,

The form of character data storage in memory and its usage (C implementation) 1, put a word constants amount in a character variable, not actually put the character itself into the memory unit, but the corresponding ASCII code of the character into the storage unit. For example, the ASCII code for the character ' A ' is C1, ' B ' is 98, and in memory the value of the variable, c2, is shown in the following

able to represent any value of M-digits and D-decimal digits. For example, DECIMAL (5, 2) must be able to represent all values from 999.99 to 999.99. Also, symbols and decimal points must be stored, so the decimal value has been 2 bytes since MySQL3.23. For decimal (5, 2), the "longest" value (-9 9 9). 9 9) requires 7 bytes. At one end of the range of positive values, a plus sign is not required, so the MySQL data type uses it to extend the range of

without a place, and there is no time, because you need to immediately acknowledge the error with the supervisor and immediately find the MySQL log and roll back the logs. But once you have this experience, I believe it must be impressive.Oddly enough, I'm on InnoDB and MyISAM. Large data volume, the index file is extremely unlikely to delete success! To be resolved.SummarizeHowever, the truncate command is fast, but it is not safe for transactions l

There are two methods for objects: Stringify () and parse (). In the simplest case, these two methods are used to serialize the JavaScript object into a JSON string and parse the JSON string into native JavaScript;The json.stringify () output JSON string does not contain any null characters or indents, so the string saved in Jsonbook;We'll see{"title": "JavaScript Advanced Programming", "Authors": ["Nicholas C.
