Setting primary key

rohitr303
A Score Level 1

Hello ,

I have a requirement where i need to set the primary key of the cdt through an xsd and not using the interface .Which annotation can be used for the same ? I tried searching through existing CDT's for the setting primary key annotation but was not able to find one. Any help will be appreciated.

Thanks,

Rohit Ouhal

    Hi ,

    The following is an example of a typical XSD file where they have used @Id for setting the primary key:

    <xsd:schema xmlns:xsd="www.w3.org/.../XMLSchema"
    xmlns:tns="urn:com:appian:types:example"
    targetNamespace="urn:com:appian:types:example">
    <xsd:complexType name="Employee">
    <xsd:sequence>
    <xsd:element name="id" nillable="true" type="xsd:int">
    <xsd:annotation>
    <xsd:appinfo source="appian.jpa">
    @Id
    @GeneratedValue
    </xsd:appinfo>
    </xsd:annotation>
    </xsd:element>
    <xsd:element name="firstName" type="xsd:string" />
    <xsd:element name="lastName" type="xsd:string" />
    </xsd:sequence>
    </xsd:complexType>
    </xsd:schema>

    Is it the only solution you are looking for or you have any other requirement ?
