Prerequisite
Synopsis
This class represents a scalar column in a table select expression tree.
When the select expression gets evaluated, the value of the
given row in the column is used.
Member Description
TableExprNodeRecordField (DataType dtype, const Block<Int>& fieldNumbers)
virtual DComplex getDComplex (const TableExprId& id)
const RecordInterface& getRecord (const TableExprId& id) const
Get the record for the last field number, thus going through
all subrecords for the other field numbers.
