Example Query - Advanced SQL Engine - Teradata Database

Consider the following data in the AggrDataTable table:

INSERT INTO AggrDataTable VALUES (1, 'george');
INSERT INTO AggrDataTable VALUES (1, 'carlos');
INSERT INTO AggrDataTable VALUES (2, 'annabelle');
INSERT INTO AggrDataTable VALUES (2, 'eva');

The following query performs the aggregation (concatenation) on the VARCHARUDT column:

SELECT aggrID, udf_agch002002udt(aggrName)
FROM AggrDataTable
GROUP BY aggrID;
