SUBSTR - SUBSTRING function extension

By Nagabhushanam Ponnapalli,

SUBSTR returns a portion of char, beginning at character @StartPos, @Length characters long.

If @StartPos is 0, it is treated as 1.

If @StartPos is positive, Oracle counts from the beginning of char to find the first character.

If @StartPos is negative, Oracle counts backwards from the end of char.
