The INSERT into Select command on the MyBatis does not end, and it concludes that SQL was written incorrectly, but it is not a problem to execute in Plsql. Finally, the problem is solved,is the setup problem.# # # Cause:java.sql.sqlsyntaxerrorexception:ora-00933:sql command did not end correctlyThe original configuration: Modified later, added aUsegeneratedkeys= "false"Problem solved smoothly, not error.

First, overview: The previous blog describes common simple algorithms: bubble sort, select sort, and insert sort. This article describes the Advanced sorting algorithm: Quick sort and merge sort. Before we begin to introduce the algorithm, we first introduce the basic knowledge required by advanced algorithms: partitioning, recursion, and incidentally introducing the binary lookup algorithm.Second, Divisio
1. Select sort
First, find the smallest element in the array;
Swap the position with the first element in the array;
Find the smallest element in the remaining array, and the second element of the group exchanges the position, so the loop repeats;
public class Selection{ // 将数组a按升序排列 public static void sort(Comparable[] a){ int N = a.length; for(int i = 0; i 2. Insert
highest on the far right. 2. Select sort: "Pull"Take the shortest and put it on the far left.The first cycle: the first position of the people out of the first position, with the rest of the people compare, if there is shorter than him, will the short pull out and the rest of the comparison, compared to the last to the shortest of the song people pulled out, the shortest man put to the first A locationSecond cycle: Take the second man out and
The bubble sort method is the earliest method used by beginners. It is easy to implement and the code is as follows:
#include
void bubble_sort(int *array, int len){ for(int i = 1; i != len; ++i){ for(int j = 0; j != len-i; ++j){ if(array[j] > array[j+1]){ int tmp = array[j]; array[j] = array[j+1]; array[j+1] = tmp; } } }}int main(){ int array[10] = {1, 3, 5, 7, 9, 0, 8, 6, 4, 2}; bubble_sort(array,
) One { A if(a[j]>a[j+1]) - { - intt=A[j]; thea[j]=a[j+1]; -a[j+1]=T; - } - } + } - intMain () + { AStd::ios::sync_with_stdio (false); atCin>>N; - for(intI=1; i) -Cin>>A[i]; - Bubble_sort (a); - for(intI=1; i) -cout" "; incoutEndl; - return 0; to}Remember bubble sort just need to remember a little, each time is two adjacent elements to compare and exchange, each time the big element has been changed to the back, a total of n times in the
