Julian Hyde updated CALCITE-1414: --------------------------------- Fix Version/s: 1.11.0 > Add a RANDOM function > --------------------- > > Key: CALCITE-1414 > URL: https://issues.apache.org/jira/browse/CALCITE-1414 > Project: Calcite > Issue Type: Bug > Reporter: Julian Hyde > Assignee: Julian Feinauer > Labels: newbie > Fix For: 1.11.0 > > > Add a RANDOM function. > It is not standard SQL, but most DBMSs have one, and it be useful. > It will also allow us to better test non-deterministic expressions. > I propose that: > * {{RANDOM\(n)}} returns an integer between 0 and n - 1 inclusive. > * There is no facility to specify a seed at this time. > * The random number generator is randomly seeded at query start time based on > (say) the method used by Java's {{new Random()}}; if you run the query twice, > you will (probably) not get the same results. > * If you call the function twice in the same row, it will (probably) return > different results. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
