We are trying to fetch the data from View only, and yes it is read only. i havetried creating the table through datastore, but it is displaying to correct the annotation:

<xsd:element name="prospectName" nillable="true" type="xsd:string">
<xsd:annotation>
<xsd:appinfo source="appian.jpa">
                                        @Id
                              @GeneratedValue
                              @Column(name = "prospect_name", columnDefinition="uniqueidentifier")
                              </xsd:appinfo>
</xsd:annotation>
</xsd:element>
