有如下存储过程: DELIMITER // CREATE PROCEDURE CountProc1(IN s_gender VARCHAR(50),OUT n
A: A.CALL CountProc1(in "女",out @num);
B: B.SELECT CountProc1("女",@num);
C: C.DECLARE CountProc1("女",out @num);
D: D.CALL CountProc1("女",@num);
A: A.CALL CountProc1(in "女",out @num);
B: B.SELECT CountProc1("女",@num);
C: C.DECLARE CountProc1("女",out @num);
D: D.CALL CountProc1("女",@num);
举一反三
- 下列用于删除存储过程的SQL语句中,正确的是()。 A: A.DROP PROC CountProc1; B: B.DELETE PROC CountProc1; C: C.DROP PROCEDURE CountProc1; D: D.DELETE PROCEDURE CountProc1;
- 执行如下代码片段后,num的值为:int num = 5;num = (num % 2) == 0 ? num – 1 : num + 1; A: 1 B: 4 C: 5 D: 6
- 回文数判断。如果n的各位数字反向排列所得自然数与n相等,则n被称为回文数。从键盘输入一个5位数字,判断是否是回文数的条件是( ) A: num[0]==num[-1] B: num[0]==num[-1] and num[1]==num[-2] C: num[1]==num[-2] D: num[0:L-1]==num[-1:-L]
- 编写一个函数判断客户输入一个数字为1位、2位还是更多为,代码如下:请补全空下的代码num=int(input("输入一位或两位的数字:"))n='0'(1)n='1'(2)n='2'(3)d='>;2'print(n+"位数。”) A: 1: if num>;-10 and num<;10:2: eilf num >;-100 and num<;100:3: else: B: 1: if num>;10 and num<;-10:2: eilf num >;-100 and num<;100:3: else: C: 1: if num>;-10 and num<;10:2: eilf num <;-100 and num>;100:3: elif: D: 1: if num>;-100 and num<;100:2: eilf num >;-10 and num<;10:3: else:
