Oracleデータベース
Oracle Database Online Documentation 12 cから リリース1(12.1):
CREATE [ GLOBAL TEMPORARY ] TABLE [ schema. ] table { relational_table | object_table | XMLType_table } ;
以下に、3つのオプションのそれぞれについて詳しく説明します。
ratio_table
[ (relational_properties) ] [ ON COMMIT { DELETE | PRESERVE } ROWS ] [ physical_properties ] [ table_properties ]
object_table
OF [ schema. ] object_type [ object_table_substitution ] [ (object_properties) ] [ ON COMMIT { DELETE | PRESERVE } ROWS ] [ OID_clause ] [ OID_index_clause ] [ physical_properties ] [ table_properties ]
XMLType_table
OF XMLTYPE [ (oject_properties) ] [ XMLTYPE XMLType_storage ] [ XMLSchema_spec ] [ XMLType_virtual_columns ] [ ON COMMIT { DELETE | PRESERVE } ROWS ] [ OID_clause ] [ OID_index_clause ] [ physical_properties ] [ table_properties ]
これらのそれぞれで利用可能なその他のオプションの詳細については、Oracleの公式ドキュメントを参照してください。
GUIの使用
テーブルの作成は、各データベース管理システムのGUIを介して、またはその製品で使用できるGUIツールのいずれかを使用して行うこともできます。
たとえば、MySQL Workbenchを使用する場合は、GUIを介してテーブルを作成できます。
