通过 SQL，根据 "FirstName" 列降序地从 "Actor" 表返回所有记录的正确表述是（）。
A: SELECT * FROM Actor SORT 'FirstName' DESC
B: SELECT * FROM Actor ORDER BY FirstName DESC
C: SELECT * FROM Actor ORDER FirstName DESC
D: SELECT * FROM Actor SORT BY 'FirstName' DESC
A: SELECT * FROM Actor SORT 'FirstName' DESC
B: SELECT * FROM Actor ORDER BY FirstName DESC
C: SELECT * FROM Actor ORDER FirstName DESC
D: SELECT * FROM Actor SORT BY 'FirstName' DESC
举一反三
- 通过 SQL，根据 "FirstName" 列降序地从 "Actor" 表返回所有记录的正确表述是 A: SELECT * FROM Actor SORT BY 'FirstName' DESC B: SELECT * FROM Actor ORDER FirstName DESC C: SELECT * FROM Actor SORT 'FirstName' DESC D: SELECT * FROM Actor ORDER BY FirstName DESC
- 从 "actor" 表中选取 "FirstName" 列的SQL语句是（ ）。 A: select actor.FirstName B: extract FirstName from actor C: select FirstName from actor D: update FirstName from actor
- 通过 SQL，您如何根据 "FirstName" 列降序地从 "Persons" 表返回所有记录？ A: SELECT * FROM Persons SORT 'FirstName' DESC B: SELECT * FROM Persons ORDER BY FirstName DESC C: SELECT * FROM Persons ORDER FirstName DESC D: SELECT * FROM Persons SORT BY 'FirstName' DESC
- 通过 SQL，从 “actor” 表中选取 "FirstName" 列的值等于"John" 的所有记录的表述正确的是（ ）。? SELECT * FROM Actor WHERE FirstName='John'|SELECT * FROM Actor WHERE FirstName LIKE 'John'|SELECT [all] FROM Actor WHERE FirstName='John'|SELECT [all] FROM Actor WHERE FirstName LIKE 'John'
- 通过 SQL，从 "Actor" 表中选取 "FirstName" 列的值以 "a" 开头的所有记录的表述正确的是（ ）。 A: SELECT * FROM Actor WHERE FirstName='%a%' B: SELECT * FROM Actor WHERE FirstName='a' C: SELECT * FROM Actor WHERE FirstName LIKE '%a' D: SELECT * FROM Actor WHERE FirstName LIKE 'a%'
