1) Write the SQL code to add a column that shows the full name of the Employee in the Employee Table. The expecting format should be “Firstname Initial Lastname” (e.g., “John G News” for the EMP_NUM 101)
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.
Employee Table. The expecting format should be “Firstname Initial Lastname” (e.g.,
“John G News” for the EMP_NUM 101)
2) Write the SQL code to add a binary variable “Hire_prior_2000” in the Employee table.
If the hire year (year of hire needs to be identified) is prior to 2000, then
Hire_prior_2000=1, other wise Hire_prior_2000=0.
