There is a field type, and we want to randomly retrieve 10 records from the table, five Types = 1 and five other types = 0, for example: As I thought, this is not simple. According to the requirements, every top 5 is taken. Since it is a random que

Technically speaking, this practice leads to undefined behavior, but the general result is that set ends with two copies of 10 values, that is, it is no longer a set. By using less_equal as our comparison type, we destroy the container! In addition, any comparison function that returns true for equal values will do the same thing. According to the defini
