Description
The expression function SUBSTR allows a user to enter a negative number as the start position of a substring. If a negative number is entered, the start of the substring is calculated from the end of the source string according to the provided index. The current default implementation of this function does not support this. Instead, it returns a string from the 1st position of the source string.
