Camille needs to identify the number of projects that have a final cost of more than $100,000 and those that were completed in 2019. Create formulas that provide this information as follows: In cell K11, create a formula using the DCOUNT function to count the number of projects with final costs of more than $100,000, using the data in the entire Projects table (Projects[#All]) and counting the values in the column of final costs ("Final Cost") that are equal to the values in the range J9:J10. In cell K15, create a formula using the DCOUNTA function to count the number of projects completed in 2019, using the data in the entire Projects table (Projects[#All]) and counting the values in the column of completion dates ("Completed") that are equal to the values in the range J13:J14.
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.
