Class representing a function in table select expression.
Internal
This class represents a function in a table select tree. The rownumber function is represented by class TableExprNodeRownr . The rowid function is represented by class TableExprNodeRowid . The rand function is represented by class TableExprNodeRandom .
When one wants to add a function to the table selection grammar, the following has to be done:
