Тази статия съдържа SQL CREATE TABLE
синтаксис, както се изпълнява от различни системи за управление на бази данни (СУБД). Синтаксисът е посочен точно както всеки доставчик го е посочил на своя уебсайт. Щракнете върху приложимата връзка, за да видите повече подробности за синтаксиса за конкретен доставчик.
Обхванатите СУБД са MySQL, SQL Server, PostgreSQL и Oracle Database.

обект_таблица
OF [ schema. ] object_type [ object_table_substitution ] [ (object_properties) ] [ ON COMMIT { DELETE | PRESERVE } ROWS ] [ OID_clause ] [ OID_index_clause ] [ physical_properties ] [ table_properties ]

Вижте официалната документация на Oracle за подробности относно допълнителните опции, достъпни за всяка от тях.
Използване на GUI
Създаването на таблици може да се извърши и чрез GUI във всяка от системите за управление на база данни или чрез използване на някой от инструментите на GUI, налични за използване с този продукт.
Например, можете да създадете таблица чрез GUI, когато работите с MySQL Workbench.
