the order of the winning red part, you can understand why. Because the first query returns a column that has more bytes than Max_length_for_sort_data, which causes the sort to be sorted in a regular order, in which case MySQL sorts the rowid and turns random io into sequential io, so it returns 5 in front, 6 in the back While the second query is optimized, there is no process to skim the data for the second time, and the relative position of the sorted record is maintained.

String class:1. for the Equality judgment of a string object, use the Equals () method instead of = =. The Equals () of string determines whether the current string is consistent with the contents of the passed-in string.2. string is a constant, and its object cannot be changed once it has been created. When using the + stitching string, a new string object is generated instead of appending content to the original string object.3. string pool is in stack memory.4. String s = "

Using a cross tabulation, We can display items in a column field, such as [subject] to display [exam scores]. can the [job score] be displayed in the same cross tabulation query at the same time?
For example, the following dataTable 3+ ----- + -------- + ------- + ------ + ------------- +| ID | sname | sclass | course | score | homeworkscore |+ ----- + -------- + ------- + ------ + ------------- +| 1 | AAA | 3 | language | 50 | 8 || 2 |
