substring
Part of a string, or the function/method that returns part of a string

substring functions/methods come in basically two flavours:

  • The parameters to the function are start index and length.
    • SQL's version uses this flavour, notably using one-based indexing
  • The parameters to the function are start index and end index. C like languages (including Java) use this flavour, and all use zero-based indexing

Definition

  • A substring is a string contained in a given string.

  • The substring can start at any index of the given string and finish in any index within the given string following the start.

  • It can be an empty string, the entire given string, or (most likely) a shorter string completely encompassed by the given string.
