Relationship Search Criteria

You can search the record based on:

  • Relationship attributes of any relationship defined for current repository
  • Existence of related records
  • Count of related records (for example, a customer which has two associated banks)
  • Attributes from target repository.

The RelationshipData tag defines how to specify the relationship criteria for the repository. For example: 

<Transaction>
<Command type="Query">
<StartCount>1</StartCount>
<MaxCount>1000</MaxCount>
<MasterCatalogRecord etype="Entity">
<!-- Base master catalog attributes -->
<ExternalKeys>
<Key name="MASTERCATALOGNAME" type="string">Customer</Key>
<Key name="PRODUCTID">a2</Key>
<Key name="PRODUCTIDEXT">a2</Key>
<Key name="FIRSTNAME">John</Key>
</ExternalKeys>
<!-- Relationship search criteria -->
<RelationshipData>
<!-- flags exists , count -->
<Relationship checkExistence ="true" count="2">
<RelationType>CustomerAccount</RelationType>
<!-- Relationship attributes -->
<RelationshipAttributes>
<Attribute name="type">SAVING</Attribute>
</RelationshipAttributes>
<!-- target master catalog attributes.-->
<Record>
<ExternalKeys>
<Key name="BALANCE" >39000</Key>
</ExternalKeys>
<!-- second level relationship search -->
<RelationshipData>
<Relationship checkExistence ="false">
<RelationType>AccountAddress</RelationType>
<RelationshipAttributes>
