I am having difficulty using the @SecondaryTable annotation. My goal

lindat over 11 years ago

I am having difficulty using the @SecondaryTable annotation.

My goal was to change from saying:
pv!software.softwareCategory.name
to:
pv!software.softwareCategoryName

The error I’m currently getting when I try to verify my data store is: “The data source schema does not match the type mappings: Missing table: sss_sw_category”

I modified an existing CDT (that verified just fine) from:
<xsd:complexType name="SSS_Software">
<xsd:annotation>
<xsd:appinfo source="appian.jpa">
@Table(name="SSS_SOFTWARE")
</xsd:appinfo>
</xsd:annotation>
...
<xsd:element name="softwareCategory" type="sss:SSS_SoftwareCategory">
<xsd:annotation>
<xsd:appinfo source="appian.jpa">
@ManyToOne(cascade=CascadeType.REFRESH)
@JoinColumn(name="CATEGORY_ID")
</xsd:appinfo>...

Linda, isn't the name of your second table called SSS_SoftwareCategory and not SSS_SW_CATEGORY?

SSS_SoftwareCategory is my CDT name while SSS_SW_CATEGORY is the corresponding Oracle table name. I have only seen CDT names used in XSD element type attribute values, never in JPA annotations. It would be helpful to me to have a complete example to look at. Last week's Data Design for Success Webinar included some incomplete sample syntax as does the "Create Custom Data Types" Appian 7.2 documentation page.

Linda, I believe you should be using the CDT name. The CDT names also reflects the data entities in the data store.
