Example: Performing Data Type Conversions Using Teradata Extensions to the ANSI CAST Syntax

Using Teradata extensions to the ANSI CAST syntax:

CREATE TABLE t2 (f1 TIME(0) FORMAT 'HHhMIm');
   
INSERT t2 (CAST('15h33m' AS TIME(0) FORMAT 'HHhMIm'));
   
SELECT f1 FROM t2;

The result from the SELECT statement is:

    f1
------
15h33m
