Lars Hofhansl commented on PHOENIX-1516:
----------------------------------------
Thanks [~julianhyde]. I do not quite follow the streams argument. That's from
the MySQL documentation, right?
It does not clarify whether each call to RAND() produces a new value or whether
it's once per row. They seem to imply the former.
Seems easiest now to make RAND() PER STATEMENT, and have each invocation of
RAND() return a new random value - via evaluate. That would also alleviate any
locking concerns in Java's Random() constructor.
Thoughts?
> Add RANDOM built-in function

> I often find it useful to generate some rows with random data.
> Here's a simple RANDOM() function that we could use for that.
