The Ministry of Women and Child Development has launched #Childline1098 childline contest to spread awareness on human trafficking. 

Human trafficking is the trade of humans for the purpose of forced labour, sexual slavery, or commercial sexual exploitation for the trafficker or others.

The WCD Ministry has invited people to share images of the logo of Childline 1098, the nationwide emergency helpline for children in distress, that they spot at unique locations and send it with a tagline to win a cash price, in a bid to spread awareness on trafficking.

The contest has been organised to mark 'World Day against Trafficking in Persons' on July 30.

The Childline has been operating at 450 locations, including 76 key railway stations, across the country.

The atomic mass of an element depends upon the number of protons, electrons and neutrons in the atoms which make the elements.

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.

Smoke alarms are also necessary in public places like banks, theaters, rest rooms, aeroplanes,...
