Classes that implement IRelQueryTable

Classes Description
RelQueryTable An object that joins two datasets based on common data values.

Remarks

The IRelQueryTable interface allows you to get the source and destination as well as the RelationshipClass or MemoryRelationshipClass used to define the RelQueryTable. The source and destination can be Tables, FeatureClasses, or even other RelQueryTables.

For example, if you wanted to join two tables to a feature class, you would first create RelQueryTableA to join one of the tables to the feature class. You would then create RelQueryTableB to join the second table to RelQueryTableA. RelQuerytableA would be the source for RelQueryTableB. The diagram below illustrates how this works.
