How to: |
GET_TOKEN extracts a token (substring) based on a string that can contain multiple characters, each of which represents a single-character delimiter.
GET_TOKEN can be optimized if there is a single delimiter character, not a string containing multiple delimiter characters.
GET_TOKEN(string, delimiter_string, occurrence)
where:
Alphanumeric
Is the input string from which the token will be extracted. This can be an alphanumeric field or constant.
Alphanumeric constant
Is a string that contains the list of delimiter characters. For example, '; ,' contains three delimiter characters, semi-colon, blank space, and comma.
Integer constant
Is a positive integer that specifies the token to be extracted. A negative integer will be accepted in the syntax, but will not extract a token. The value zero (0) is not supported.
