Max Philipp Wriedt reopened TORQUE-369:
---------------------------------------
I thought about it a little longer, i completely ignored the "foreign key
checks = 0" part.
So this is still the right place to discuss this, also for ExternalSchema
> LoadExternalSchemaTransformer recursively includes when cross-referencing

> Key: TORQUE-369
> URL: https://issues.apache.org/jira/browse/TORQUE-369
> Project: Torque
> Issue Type: Bug
> Components: Templates
> Affects Versions: 5.1, 6.0
> Reporter: Max Philipp Wriedt
> Assignee: Max Philipp Wriedt
> Priority: Major
>
> When referencing an external schema (to use foreign key references in another
> schema definition) and back referencing to its origin, we get an infinite
> recursion.
> Affects:
> org.apache.torque.templates.transformer.LoadExternalSchemaTransformer.transform()
> Example:
> First Schema:
> {code:java}
> <?xml version="1.0" encoding="UTF-8" ?>
> <database>
> <external-schema filename=secondary-schema.xml" />
> <table name="test" javaName="Test">
> <column name="Id" javaName="Id" required="true" type="INTEGER"
> primaryKey="true"/>
> <column name="Name" javaName="Name" required="true" type="VARCHAR"
> size="5"/>
> <column name="foreign-key" javaName="ForeignKey" required="true"
> type="INTEGER" size="2"/>
> <!-- define foreign key to secondary scheme!-->
> </table>
> </database>{code}
> Second Schema:
> {code:java}
> <?xml version="1.0" encoding="UTF-8" ?>
> <database
> xmlns="http://db.apache.org/torque/5.0/templates/database";
> xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
> xsi:schemaLocation="http://db.apache.org/torque/5.0/templates/database
>
> https://db.apache.org/torque/torque-5.0/documentation/orm-reference/database-5-0-strict.xsd";
> name="test" defaultIdMethod="native" defaultJavaType="object">
> <external-schema filename=first-schema.xml" />
> <table name="foreign-key" javaName="Test">
> <column name="Id" javaName="Id" required="true" type="INTEGER"
> primaryKey="true"/>
> <column name="Name" javaName="Name" required="true" type="VARCHAR"
> size="5"/>
> </table>
> <table name="test2" javaName="Test2">
> <column name="Id" javaName="Id" required="true" type="INTEGER"
> primaryKey="true"/>
> <column name="Name" javaName="Name" required="true" type="VARCHAR"
> size="5"/>
> <column name="foreign-key" javaName="ForeignKey" required="true"
> type="INTEGER" size="2"/>
> <!-- define foreign key to first scheme!-->
> </table>
> </database>{code}
