In almost each of the six Teradata SQL reference manuals, the usage of a clause is explained in a particular notation. I am having difficulty understanding that notation and hence unable to understand the syntax. Can anybody tell me how to read that notation? Please provide a document or a link to a document/webpage that describes that notation. Thanks,NDTue, 27 May 2008 01:30:04 GMTND
