Write a SQL query, which shows a list of all employees last name, their department names and their department city where that department is located from the employees table. If an employee does not belong to a department, then their department number should show as “N/A” and their department city should show up as “No City info Found”. MAKE SURE you have all the employees displayed including the employees who do not have a department.
SQL
SQL stands for Structured Query Language, is a form of communication that uses queries structured in a specific format to store, manage & retrieve data from a relational database.
Queries
A query is a type of computer programming language that is used to retrieve data from a database. Databases are useful in a variety of ways. They enable the retrieval of records or parts of records, as well as the performance of various calculations prior to displaying the results. A search query is one type of query that many people perform several times per day. A search query is executed every time you use a search engine to find something. When you press the Enter key, the keywords are sent to the search engine, where they are processed by an algorithm that retrieves related results from the search index. Your query's results are displayed on a search engine results page, or SER.
