Hint: starts with 044 First, create a MySQL database or use an existing database (make sure to use a UTF8 character set, like utf8mb4) and then create a table in the database called "Ages": CREATE TABLE Ages ( `name` VARCHAR(128), age INTEGER ); Then make sure the table is empty by deleting any rows that you previously inserted, and insert these rows and only these rows with the following commands: DELETE FROM Ages; INSERT INTO Ages (`name`, age) VALUES ('Aylesha', 26); INSERT INTO Ages (`name`, age) VALUES ('Awwal', 23); INSERT INTO Ages (`name`, age) VALUES ('Kathryn', 19); INSERT INTO Ages (`name`, age) VALUES ('Penelope', 22); Once the inserts are done, run the following SQL command: SELECT sha1(CONCAT(`name`,age)) AS X FROM Ages ORDER BY X; Find the first row in the resulting record set and enter the long string
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.
