BizTalk Schema Special Charcter Node Name issue

Hi,

I generated a schema from SQL Adapter.

My Table name @Emp (i need to keep this @ symbol…)

when i am trying to process the map, Biztalk error  @Emp node name error.

i know biztalk schema not allows special charecters as a node name…how to resolve this issue.

i tried adding this in the schema, i can't open xsd….not accepting added elements

      <xs:restriction base="xs:Name">

<pattern value="[^`~!@#$%^&amp;*()+=\[\]{}\|;'&quot;&gt;&lt;,\?\\]+" />

   </xs:restriction>

Any help appreciated…

Thanks
