我正在寻找创建一个select语句，当两个行的串联不同时，我选择所有列和行。我在下面有我的SQL语句。但是，我不确定如何正确创建此声明，如何编写此声明？
$query = "SELECT * FROM APPROVED
WHERE DISTINCT CONCAT(P_NUMBER,'-',A_NUMBER) AS CNUMBER
AND (STATUS = 'ACTIVE' OR STATUS = 'CLOSED' OR STATUS = 'CLOSING' OR STATUS = 'PENDING')";
答案 0 :(得分：0)
DISTINCT用于列选择。有几种方法可以做到这一点：
$scope.company.push("Other")// May it be a object
应该与
几乎完全相同import java.util.Scanner;
import java.util.Random;

public static void main(String[] args) {
