About SQL

To perform many of its operations, Oracle Enterprise Manager Database Control (Database Control) submits structured query language (SQL) statements to the database. SQL (pronounced like sequel) is an industry-standard English-like computer programming language for querying and updating databases.

The following is an example of a SQL query that lists information about countries in a countries table, which is owned by user hr:

SELECT COUNTRY_ID, COUNTRY_NAME FROM HR.COUNTRIES;

SQL is a powerful language that can also be used to perform a variety of database administration tasks. The following SQL statement creates the database user nick and assigns him a password of your choosing, represented by password:

CREATE USER nick IDENTIFIED BY password;

When performing an administrative task in Database Control, you can click Show SQL to see the SQL statements that Database Control generates and submits.
