Class ToTableMapping

java.lang.Object

com.exasol.adapter.document.edml.ToTableMapping

All Implemented Interfaces:

MappingDefinition

public final class ToTableMapping
extends Object
implements MappingDefinition

Java representation of the EDML toTableMapping. This mapping is used for normalizing documents to table structures. It creates a new table in the resulting virtual schema named: <NAME_OF_PARENT>_<GIVEN_NAME>.

You can define the columns of this table using the mapping property. If the parent table defines a key using one or more toVarcharMappings for a key or secondary index in the document database, this will be used as foreign key.
