test命令用于求逻辑表达式的值,那么下列写法不正确的是()
A: test$user_name="Roger"
B: [$name_name="Roger"]
C: testuser_name="Roger"
D: [user_name="Roger"]
A: test$user_name="Roger"
B: [$name_name="Roger"]
C: testuser_name="Roger"
D: [user_name="Roger"]
举一反三
- The boys name was NOT(Check all that apply) A: Robert B: Lewis C: Langston D: Randy E: Roger
- 已知list_1 = [1,4,6,'name',6.6],则执行 list_1.extend([8,'test'])后,list_1的值是多少()。 A: [1,4,6,'name',6.6,[8,'test']] B: [1,4,6,'name',6.6,8,'test'] C: [1,4,6,'name',6.6,8] D: [1,4,6,'name',6.6,'test']
- 在tb_name表中创建一个名为name_view的视图,并设置视图的属性为name、pwduser,执行语句是什么?( ) A: CREATE VIEW name_view(name,pwd,user)AS SELECT name.pwd,user FROM tb_mame; B: SHOW VIEW name_view(name,pwd,user) AS SELECT name,pwd,user FROM tb_mame: C: DROP VIEW name_view(name,pwd,user) AS SELECT name,pwd,user FROM tb_mame: D: SELECT * FROM name_view(name,pwd,user) AS SELECT name,pwd,user FROM tb_ name:
- 下列哪些SQL语句可以查询出User表中name为张三的记录()。 A: SELECT * FROM User WHERE name = ’张三’ B: SELECT * FROM User WHERE name = ’张三’ LIMIT 0,1 C: SELECT * FROM User WHERE name LIKE ’张三’ D: SELECT * FROM User WHERE name LIKE ’%张三%’
- 下列是将所有与JavaBean对象属性同名的传入参数的值赋值给对应的同名属性,从而使用一个setProperty动作一次性完成对多个属性的赋值是( )。 A: <jsp:setProperty name="user" property ="name" value ="Lily" /> B: <jsp:setProperty name="user" property ="name" param ="name" /> C: <jsp:setProperty name="user" property ="name" /> D: <jsp:setProperty name="user" property =" *" />
