> Add support for updating child objects

>
> Key: TEIID-4516
> URL: https://issues.jboss.org/browse/TEIID-4516
> Project: Teiid
> Issue Type: Feature Request
> Components: JDG Connector
> Affects Versions: 8.12.7.6_3, 9.2
> Reporter: Jan Stastny
> Assignee: Van Halbert

> When using complex pojo with JDG 6.6, updating child tables doesn't do anything. It doesn't update the rows, but neither throws exception.
> The problem appears for both usages of JDG cache (annotated POJOs, protobuf+marshaller). I have following pojo structure:
> {code:plain}
> package org.jboss.qe.jdg.remote.protobuf.complex;
> /* @Indexed */
> message Person {
>
> /* @IndexedField(index=true, store=false) */
> required int32 id = 1;
>
> /* @IndexedField */
> required string name = 2;
>
> /* @IndexedField */
> optional string email = 3;
>
> /* @IndexedField(index=true, store=false) */
> repeated PhoneNumber phones = 4;
> /* @Indexed */
> message Address {
>
> /* @IndexedField */
> required string Address = 1;
>
> /* @IndexedField(index=true, store=false) */
> required string City = 2;
>
> /* @IndexedField(index=true, store=false) */
> required string State = 3;
> }
> /* @IndexedField(index=true, store=false) */
> optional Address address = 5;
> }
>
> /* @Indexed */
> message PhoneNumber {
>
> /* @IndexedField */
> required string number = 1;
> }
> {code}
> That is, one top-level POJO class Person, and two child POJO classes: Address(1-to-1) and PhoneNumber(1-to-N). Neither Address nor PhoneNumber tables could be updated. The DDL is following:
> {code:sql}
> CREATE FOREIGN TABLE Address (
> Address string NOT NULL PRIMARY KEY OPTIONS (NAMEINSOURCE 'address.Address', SEARCHABLE 'Searchable', NATIVE_TYPE 'java.lang.String'),
> City string NOT NULL OPTIONS (NAMEINSOURCE 'address.City', SEARCHABLE 'Searchable', NATIVE_TYPE 'java.lang.String'),
> State string NOT NULL OPTIONS (NAMEINSOURCE 'address.State', SEARCHABLE 'Searchable', NATIVE_TYPE 'java.lang.String'),
> id integer NOT NULL OPTIONS (NAMEINSOURCE 'id', SELECTABLE FALSE, SEARCHABLE 'Searchable', NATIVE_TYPE 'int'),
> CONSTRAINT FK_PERSON FOREIGN KEY(id) REFERENCES Person (id) OPTIONS (NAMEINSOURCE 'address')
> ) OPTIONS (UPDATABLE TRUE);
>
> CREATE FOREIGN TABLE Person (
> id integer NOT NULL OPTIONS (NAMEINSOURCE 'id', SEARCHABLE 'Searchable', NATIVE_TYPE 'int'),
> name string NOT NULL OPTIONS (NAMEINSOURCE 'name', SEARCHABLE 'Searchable', NATIVE_TYPE 'java.lang.String'),
> email string OPTIONS (NAMEINSOURCE 'email', SEARCHABLE 'Searchable', NATIVE_TYPE 'java.lang.String'),
> CONSTRAINT PK_ID PRIMARY KEY(id)
> ) OPTIONS (UPDATABLE TRUE);
>
> CREATE FOREIGN TABLE PhoneNumber (
> number string NOT NULL PRIMARY KEY OPTIONS (NAMEINSOURCE 'phones.number', SEARCHABLE 'Searchable', NATIVE_TYPE 'java.lang.String'),
> id integer NOT NULL OPTIONS (NAMEINSOURCE 'id', SELECTABLE FALSE, SEARCHABLE 'Searchable', NATIVE_TYPE 'int'),
> CONSTRAINT FK_PERSON FOREIGN KEY(id) REFERENCES Person (id) OPTIONS (NAMEINSOURCE 'phones')
> ) OPTIONS (UPDATABLE TRUE);
> {code}
> INSERT queries to prepare data:
> {code:sql}
> INSERT INTO Person(id,name,email) VALUES (1,'name1','email1')
> INSERT INTO Address(id,Address,City,State) VALUES (1,'address1','city1','state1')
> INSERT INTO PhoneNumber(id, number) VALUES (1, '001234567')
> INSERT INTO PhoneNumber(id, number) VALUES (1, '001234568')
> {code}
> UPDATE queries and queries for checking results:
> * 1-to-1
> {code:sql}UPDATE Address SET city='newCity' WHERE id=1{code}
> {code:sql}SELECT * FROM Person,Address{code}
> * 1-to-n
> {code:sql}UPDATE PhoneNumber SET number='newNumber' WHERE id=1{code}
> {code:sql}SELECT * FROM Person,PhoneNumber{code}
