When an XML Schema is generated from an Oracle database (DB), the Oracle DB datatypes are converted to XML Schema datatypes as listed in the table below.
XML Schema Datatype |

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 |
