第14题:
14、Choose three.
Examine the description of the CUSTOMERS table:
Name Null? Type
----------------------------------------------------------------------------
CUSTOMER_ID NOT NULL NUMBER(38)
CUSTOMER NAME NOT NULL VARCHAR2 (100)
INSERT_DATE NOT NULL DATE
Which three statements will do an implicit conversion?
A) SELECT * FROM customers WHERE TO_DATE (insert_date) = DATE '2019-01-01';
B) SELECT * FROM customers WHERE customer_id = '0001' ;
C) SELECT * FROM customers WHERE TO_CHAR (customer_id) = '0001' ;
D) SELECT * FROM customers WHERE customer_id = 0001;
E) SELECT * FROM customers WHERE insert_date = DATE '2019-01-01' ;
F) SELECT * FROM customers WHERE insert_date = '01-JAN-19' ;
Answer:BEF
(解析:BF 答案比较简单,E 答案以前没有碰到,后面的 DATE 不是转换函数,只是一个提示,oracle 会隐式转换。)
