NEW QUESTION # 111
Which three statements are true about built-in data types?

A. A CHAR column definition does not require the length to be specified.
B. A BLOB stores unstructured binary data within the database.
C. A VARCHAR2 column definition does not require the length to be specified.
D. The default length for a CHAR column is always one character.
E. A VARCHAR2 blank-pads column values only if the data stored is non-numeric and contains no special characters.
F. A BFILE stores unstructured binary data in operating system files.

Answer: B,F

Explanation:
D: True. A BLOB (Binary Large Object) is used to store unstructured binary data within the Oracle Database. It can hold a variable amount of data.
F: True. A BFILE is a datatype in Oracle SQL used to store a locator (pointer) that points to binary data stored in operating system files outside of the Oracle Database.
Both BLOB and BFILE are used for large binary data but differ in where the data is actually stored - BLOB stores the data inside the Oracle Database, whereas BFILE stores the data in the file system outside the database.
Reference:
The Oracle Database SQL Language Reference guide details the characteristics and uses of BLOB and BFILE datatypes among others, describing their storage characteristics and data type definitions.
