下列查询语句能够正确执行的是()。
A: SELECT c1,c2,MAX(c3) FROM table_name HAVING c1>;1
B: SELECT c1,c2,MAX(c3) FROM table_name GROUP BY c1 HAVING c2>;1
C: SELECT c1,c2,MAX(c3) FROM table_name GROUP BY c1,c2 HAVING c2>;1
D: SELECT c1,c2,MAX(c3) FROM table_name WHERE c1>;1 GROUP BY c2 HAVING c2>;1
A: SELECT c1,c2,MAX(c3) FROM table_name HAVING c1>;1
B: SELECT c1,c2,MAX(c3) FROM table_name GROUP BY c1 HAVING c2>;1
C: SELECT c1,c2,MAX(c3) FROM table_name GROUP BY c1,c2 HAVING c2>;1
D: SELECT c1,c2,MAX(c3) FROM table_name WHERE c1>;1 GROUP BY c2 HAVING c2>;1
举一反三
- 执行 int c1=1,c2=2,c3; c3=c1/c2; 后,c3的值是( ) A: 0 B: 1/2 C: 0.5 D: 1
- int c1=1 , c2=2 , c3;c3=c1/c2; 执行程序段后,c3中的值是:( ) A: 0 B: 1 C: 0.5 D: 1/2
- 若int c1 = 1, c2 = 2, c3; c3 = 1.0 / c2 * c1;,则c3的值是( )。 A: 0 B: 0.5 C: 1 D: 2
- 若有以下程序段,c3中的值是 int c1 = 1, c2 = 2, c3;<br/>c3 = c1 / c2; A: 0.5 B: 1 C: 1/2 D: 0
- 若有以下程序段:intc1=1,c2=2,c3:c3=c1/c2: A: 0 B: 1/2 C: 0.5 D: 1
