SQL structure

В этой статье собраны и структурированы минимальные основы SQL Oracle из обширной документации базы данных Oracle 12c. Для тех, кто начинает изучение базы, эта информация поможет обрисовать общую картину. Для разработчиков и тестировщиков базы данных эти таблицы служат удобными помощниками в повседневной работе.

SQL Structured Query Language
DDL Data Definition Language (DDL) statements manage schema objects in the database. These statements create new, drop old, and establish schema objects. They also control access to schema objects.
DML Data Manipulation Language (DML) statements can change data in database tables. For example, DML statements insert new rows into a table, update column values in existing rows, delete rows from a table, lock a table in the database, and explain the execution plan for a SQL statement.

* - вместо внесения изменений через ALTER-команду можно пересоздать объект командой CREATE OR REPLACE. При этом объект сохранит статус, например, включенность триггера. ** - в документации Oracle пропущена команда, но удалить тело пакета с сохранением его спецификации позволительно
