SQL is the new essential in the world which is dominated by data. It doesn't matter whether you are a sales professional, an HR, or a data analyst, SQL has gradually become a prerequisite for every job profile type. This is mainly because its a universal application for data extraction and various people with varied skill set can use it as per their own use. For example, an HR professional would need SQL only for the extraction of data from the server and therefore would only need a #beginnersql to #intermediate level of #sql.
Whereas, a data analyst has to use #sqlqueries for various use such as #extractionofdata using complex queries, #cleaning of data, and further analysis of data using either #sql, #excel, or #python. Hence, to be a #dataanalyst , a person should possess anywhere between intermediate to expert level proficiency on SQL.

This video will walk you through Hackerrank's SQL Basic Level Question - Revising the SELECT Query 1

'Query all columns for all American cities in the CITY table with populations larger than 100000. The CountryCode for America is USA. '

Query:

SELECT NAME FROM City
WHERE Population (use greater than symbol) 120000
AND
CountryCode = 'USA'

This query is written as per the SQL standards and would work for #mysqlserver and #mssqlserver
