Create a view, using JOBS, DEPARTMENTS, and JOB_HISTORY tables that will include department name (not ID), job title (not jobID), start date, and end date for all rows in the JOB_HISTORY table Using your view, write a query that shows the number of rows (count) for each department. Write a query that uses your view from above to select the columns department name, job title, and end date for all rows where the department name includes the string “Sale” that is NOT case-sensitive. Use a function. i.e. SALE, SaLe, Sale, sAle, etc. should all match a row
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.
