질문 # 387
BOOK_SEQ is an existing sequence in your schema.
Which two CREATE TABLE commands are valid?

A. CREATE TABLE bookings (
bk_id NUMBER(4) DEFAULT book_seq.NEXTVAL PRIMARY KEY,
start_date DATE DEFAULT SYSDATE,
end_date DATE DEFAULT SYSDATE NOT NULL);
B. CREATE TABLE bookings ( bk_id NUMBER(4),
start_date DATE DEFAULT SYSDATE,
end_date DATE DEFAULT (end_date >= start_date));
C. CREATE TABLE bookings (
bk_id NUMBER(4) DEFAULT book_seq.CURRVAL,
start_date DATE DEFAULT SYSDATE,
end_date DATE DEFAULT start date);
D. CREATE TABLE bookings (
bk_id NUMBER(4) NOT NULL DEFAULT book_seq.CURRVAL,
start_date DATE NOT NULL,
end_date DATE DEFAULT SYSDATE);
E. CREATE TABLE bookings (
bk_id NUMBER(4) NOT NULL PRIMARY KEY,
start_date DATE NOT NULL,
end_date DATE DEFAULT SYSDATE);

정답：A,E

설명：
For creating tables and utilizing sequences in Oracle 12c SQL, certain rules apply:
* Option A: This statement is valid. It creates a table with a primary key and dates, where the default value for end_date is SYSDATE. There are no constraints on sequences, and all syntax is correct.
* Option B: This option is invalid because it attempts to use CURRVAL of a sequence as a default value for a primary key. CURRVAL cannot be used until the sequence's NEXTVAL has been called in the session.
* Option C: Invalid syntax because 'start date' is not a recognized default expression in Oracle SQL. If the intention was to use 'start_date' as a reference, it still would not work correctly without proper syntax for conditional default values.
* Option D: This syntax is invalid in Oracle SQL because the DEFAULT clause does not support relational conditions directly within the table definition.
* Option E: Valid. It correctly uses NEXTVAL for a sequence in the DEFAULT clause for the primary key, ensuring that each new record has a unique primary key generated from the sequence. The start_date and end_date are assigned defaults of SYSDATE, which is syntactically correct.
