SQL Commands: TO_TIME

Published on March 3, 2022 by Kevin Graham

The TO_TIME function converts a string in a given format to a Kognitio TIME data type. It will also accept a number
instead of a string, within certain limits. It is possible to specify a literal string, a literal number, or a
database column containing a string or number. In every case but one, their format must correspond to that which is
described by a supplied format-string. Only if the string is in the format ‘HH:MM:SS’ can the format-string be left
out.

Usage

TO_TIME(datetime-string)
TO_TIME(datetime-string, format-string)
