RANDSTR

Returns a random string of specified length.

Syntax

RANDSTR( <length> , <gen> )

Usage Notes

  • Individual characters are chosen uniformly at random from the following pool of characters: 0-9, a-z, A-Z.
  • The value for the generator expression, gen, is used as the seed for this uniform random distribution. For more information about generator expressions, see Usage Notes.
