Reset the initial value of AUTO_INCREMENT In the MySQL auto-incrementing ColumnNote that existing data will be deleted using any of the following methods. Method 1:Delete from tb1;Alter table tbl AUTO_INCREMENT = 100;(Benefit, you can set AUTO_INCREMENT to start with any value)Tip: if there are many columns and data, the speed will be very slow. For example, if there are more than 0.9 million rows, it will take more than 10 minutes. Method 2:Trunc

Do not actually use floating point ++ -- Floating point numbers, including float, double, and long double, are all approximately stored.Therefore, the value of each floating point is not accurate.Therefore, if auto-increment is used in some special casesThe approximate value of A is equivalent to that of a + 1.That is, auto-increment has no effect.If it is

When Oracle is used, this situation occurs. When a module is added, only one module name is input, and there is a module ID in the table. This ID is set to auto-increment.

Next, let's take a look at the example of the c ++ overload post-auto-addition operator. If you need to learn the C ++ auto-addition operator, you can refer to it. The Code is as follows: Copy code # Include Using namespace std;Class num{Public:Int x;Num () {n = 1; cout Num (int I) {n = I; cout Num (const num s) {this-> n = s. n; cout ~ Num () {cout Int get () const {return n ;}Void
