举一反三

- 【单选题】查询student表中id字段值小于5,并且gender字段值为“女”的学生姓名的SQL语句是 A. SELECT name FROM student WHERE id<5 OR gender‘女’; B. SELECT name FROM student WHERE id<5 AND gender=‘女’; C. SELECT name FROM student WHERE id<5 ,gender=‘女’; D. SELECT name FROM student WHERE id<5 AND WHERE gender=‘女’;
- 查询姓"张"的学生姓名,下列()语句不能实现。 A: SELECT sname FROM student WHERE left(sname,1)= '张' B: SELECT snameFROM student WHERE sname LIKE '张%' C: SELECT sname FROM student WHERE substring(sname,1,1)= '张' D: SELECT sname FROM student WHERE sname='张%'
