While dealing with strings, we often require certain characters or a substring from given string. Sage X3 provides a special function to extract a substring from provided CLOB or a string.
- EXP_STRING is an expression returning a CLOB or string value.
- EXP_POS is an expression returning an integer value that is the position of the first character to be extracted.
- EXP_NB is an expression returning an integer value that defines the number of characters to be extracted.
In below example, 3 characters from 4th position of a string “Welcome!” are extracted.
It gives substring “com” as an output.
Hope this helps!
