Consider the following table and inserted data.

   CREATE TABLE t (id INTEGER, str VARCHAR(256));
   INSERT INTO t VALUES (1,'Teradata-Warehouse 13.10 - Combine 2 powerful forms of business intelligence (BI).'); 
   INSERT INTO t VALUES (2,'http://www.teradata.com/');

The following query returns the third token from the t.str string value. There are only two tokens in the second string, so the function returns NULL for that row.

SELECT id, STRTOK(t.str, ' -/', 3) FROM t;

The output from the query is:

         id  STRTOK(str,' -/',3)
-----------  ----------------------------------------------------------
          1  13.10
          2  NULL
