Oracle
当从Oracle数据库（DB）生成XML Schema时，Oracle DB数据类型会被转换为下表中列出的XML Schema数据类型。
XML Schema数据类型 | Oracle数据类型 |
xs:ID | ROWID |
xs:string | If no facets |
| if UNICODE then NVARCHAR2 (255) |
| else VARCHAR2 (255) |
| else if UNICODE |
| (Size = either length or maxLength) |
| If Size <= 2000 then NCHAR |
| if Size <= 4000 then NVARHCAR2 |
| if Size <= 4 Gigabytes then NCLOB |
| else if NON-UNICODE |
| (Size = either length or maxLength) |
| If Size <= 2000 then CHAR |
| if Size <= 4000 then VARCHAR2 |
| if Size <= 4 Gigabytes then CLOB |
