NEW QUESTION # 115

Which three statements will do an implicit conversion?

A. SELECT * FROM customers WHERE TO_ CHAR (customer_ id) = '0001';
B. SELECT. FRON customers WE TO DATE (Insert _ date) = DATE '2019-01-01';
C. SELECT * FROM customers WHERE customer_ id = 0001;
D. SELECT. FROM customers WHERE insert_ date = DATE *2019-01-01';
E. SELECT FROM customers WHERE insert date = '01-JAN-19';
F. SELECT * FROM customers WHERE customer id = '0001';

Answer: D,E,F

Explanation:
A: No implicit conversion is done here because TO_CHAR is an explicit conversion from a numeric to a string data type.
B: Implicit conversion happens here because the '0001' string will be automatically converted to a numeric data type to match the CUSTOMER_ID field.
C: No implicit conversion is needed because 0001 is already a numeric literal.
D: Implicit conversion occurs here because the string '01-JAN-19' will be converted to a date type to compare with INSERT_DATE.
E: No implicit conversion; DATE is explicitly specified using the DATE keyword.
F: Incorrect syntax, it has typographical errors and also TO_DATE is an explicit function, not an implicit conversion.
Reference for SQL functions, conversions, and the CROSS JOIN behavior can be found in the Oracle Database SQL Language Reference 12c documentation.
