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

xs:ID |
varchar(255) |
xs:string |
If no facets then varchar (255) |
|
else if facet length is set and <= 255 |
|
else if facet maxLength set and <= 255 |
|
else if maxLength is set and <= 65545 then text |
|
else if maxlength is set and <= 16777215 |
|
else if maxlength is set and <= 429496295 |
