SQL Query
In the SQL Query category, you will find numerous queries useful for administering the Oracle database. A SQL Structure Query Language query is a query to a database through SQL code, which is a standard language used to retrieve and manage information from relational databases. Oracle is an RDBMS Relational Database Management System or a DBMS Data Base Management System based on the relational model. This allows you to retrieve data from multiple tables by relating them to each other in order to have the result in a single output. A query consists of a code structure consisting of 2 phases: selection and origin. SELECT * FROM all_users; The third phase follows, which is the condition. We apply a filter to the queries to limit the rows to be recovered: SELECT * FROM all_users WHERE username = ‘ALEX’; This is a simple query that allows us to retrieve the information recorded in the all_users table relating to the ALEX user. On the Foundations of Oracle course, the SQL language in all its forms will be illustrated in detail.
