Table operators read one or more input tables, perform operations on the data such as partitioning or aggregation, then write output rows. Table operators can accept an arbitrary row format for each input table and, based on the operation and input row types, produce an arbitrary output row format. For more information on the table operators that Teradata provides, see Teradata Vantage™ - SQL Operators and User-Defined Functions, B035-1210. For more information on creating table operators, see Teradata Vantage™ - SQL External Routine Programming , B035-1147 .
