Abstract base class for a node having multiple child nodes.
Internal
TableExprNodeMulti is a node in the table expression tree which can have MULTIple child nodes.
TableExprNodeMulti is the abstract base class for all nodes in a table expression tree using multiple operands. It is used as the base class for the node classes representing functions, sets, indices, etc..
This class contains the common functionality for the classes representing a node with multiple operands.
