RAND(n)

Returns a random floating-point value v in the range 0 <= v < 1.0. To obtain a random integer R in the range i <= R < j, use the expression FLOOR(i + RAND() * (j − i)). Argument n is used as the seed value. For equal argument values, RAND(n) returns the same value each time , and thus produces a repeatable sequence of column values.

Syntax

RAND( <n>)
