NEW QUESTION # 139
Examine the description of the SALES table:

The SALES table has 5,000 rows.
Examine this statement:
CREATE TABLE sales1 (prod id, cust_id, quantity_sold, price)
AS
SELECT product_id, customer_id, quantity_sold, price
FROM sales
WHERE 1=1
Which two statements are true?

A. SALES1 has PRIMARY KEY and UNIQUE constraints on any selected columns which had those constraints in the SALES table.
B. SALES1 is created with 1 row.
C. SALES1 has NOT NULL constraints on any selected columns which had those constraints in the SALES table.
D. SALES1 Is created with 5,000 rows.

Answer: B,C

Explanation:
When creating a new table with a query, the statements that are true are:
A . SALES1 is created with 1 row.
This is incorrect actually; the given query with WHERE 1=1 will retrieve all rows from the sales table, not just one row. Therefore, SALES1 will be created with the same number of rows as in the SALES table, assuming there are no WHERE clause conditions limiting the rows.
D . SALES1 has NOT NULL constraints on any selected columns which had those constraints in the SALES table.
This is true. When a table is created using a CREATE TABLE AS SELECT statement, the NOT NULL constraints on the columns in the selected columns are preserved in the new table.
Options B and C are incorrect:
B is incorrect because the primary key and unique constraints are not carried over to the new table when using the CREATE TABLE AS SELECT syntax.
C is incorrect in the context of this scenario. However, if interpreted as a standalone statement (ignoring A), C would be the correct description of the outcome since WHERE 1=1 will not filter out any rows.

NEW QUESTION # 140
