Man's attitude to various animals changed many times in the course of centuries. From indifference or practicality, he went on to adoration and deification, and then to hatred. Ancient Egyptians, for example, highly appreciated the cat's ability to destroy rodents. The cat was much superior in this respect to the grass­snakes and weasels they had kept in their houses before. These proved unable to cope with hordes of rats which invaded Egypt from Asia. So the cat, a very useful animal, was ranked as a sacred animal and one of the most important animals, too. The goddess of the Moon, fertility and child­birth, Bast herself was portrayed by the Egyptians as a woman with a cat's head.

Sumptuous temples were built to this goddess, where cats were kept in luxury and fed the choicest of foods. They had their own priests and votaries, more numerous as a matter of fact than any other sacred animal could boast. According to the Greek historian Herodotus, the festival in the city of Bubastis, which had a temple dedicated to cats, was attended by as many as 700 thousand, who brought their offerings to the goddess in the shape of figurines of her made of gold, silver and bronze and adorned with precious stones.

Most successful companies, institutions and organizations have mission statements. Most individuals don't. As the Chief Executive Officer of your own life in the knowledge era, you need a laser like focus in your vision. You need a mission and a mission statement describing how you want to live, not just what you want to own; defining the person you want to become, not just the title you want to see on your door; outlining the knowledge you will receive, not just the degree you'll earn or your next promotion.

I began the process this way : "To be aware of the uniqueness of my associates, clients, friends and family, and to treat that uniqueness with loving concern. I was created to lead myself and others to understand win­win relationships and how to use them to improve the lives of all persons with whom I come into contact."

You, too, can frame your mission statement starting with your core values, working outward to your material desires and financial needs.

What should a person's mission statement begin with?

A) Your core values B) What you want to acquire
C) Your monetary ambitions D) Your next promotion
 
Answer & Explanation Answer: A) Your core values

Q:

A subquery in an sql select statement.

Answer

A Subquery or Inner query or a Nested query is a query within another SQL query and embedded within the WHERE clause.


Subqueries are most frequently used with the SELECT statement. The basic syntax is as follows::


SELECT column_name [, column_name ]
FROM table1 [, table2 ]
WHERE column_name OPERATOR
(SELECT column_name [, column_name ]
FROM table1 [, table2 ]
[WHERE])



A subquery is used to return data that will be used in the main query as a condition to further restrict the data to be retrieved.


Subqueries can be used with the SELECT, INSERT, UPDATE, and DELETE statements along with the operators like =, <, >, >=, <=, IN, BETWEEN, etc.


 


There are a few rules that subqueries must follow −


 


1. Subqueries must be enclosed within parentheses.


2. A subquery can have only one column in the SELECT clause, unless multiple columns are in the main query for the subquery to compare its selected columns.


3. An ORDER BY command cannot be used in a subquery, although the main query can use an ORDER BY. The GROUP BY command can be used to perform the same function as the ORDER BY in a subquery.


4. Subqueries that return more than one row can only be used with multiple value operators such as the IN operator.


5. The SELECT list cannot include any references to values that evaluate to a BLOB, ARRAY, CLOB, or NCLOB.


6. A subquery cannot be immediately enclosed in a set function.


7. The BETWEEN operator cannot be used with a subquery. However, the BETWEEN operator can be used within the subquery.
