Incorrect auto-generated id returned from Save To Data Store

Dear All,

We are using the 'Write to Data Store' smart process to write data into an Oracle DB v18c. The column 'ID' is a primary key and is auto-generated by the DB via a 'before insert' trigger that is calling a sequence. In the XSD file of the corresponding CDT we have the annotations @Id @GeneratedValue.

Writing data to the DB works fine. However, the ID value returned from the 'Write to Data Store' process is incorrect. Seems like a different sequence is used.

Any suggestions on how to solve this problem are highly appreciated. Thank you in advance!


  • Hi Fabian, 

    we use Oracle as DB and this is an example of a CDT for the primary key field

    <xsd:element name="ID_GENERIC_TABLE_NAME" nillable="true" type="xsd:int">
    <xsd:appinfo source="appian.jpa">@Id
    @Column(name="ID_GENERIC_TABLE_NAME", nullable=false, columnDefinition="NUMBER")
    @SequenceGenerator(name="SQ_GENERIC_TABLE_NAME", sequenceName="SQ_GENERIC_TABLE_NAME")
    @GeneratedValue(strategy=GenerationType.SEQUENCE, generator="SQ_GENERIC_TABLE_NAME")
