Subject [jira] Commented: (DERBY-3297) Document SIGN, SQRT, RAND, RANDOM, COSH, COT, SINH and TANH functions.
Date Thu, 10 Jan 2008 18:37:34 GMT

    [ https://issues.apache.org/jira/browse/DERBY-3297?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12557746#action_12557746

Daniel John Debrunner commented on DERBY-3297:

Actually RAND is not a synonym for RANDOM.

ij> values rand();
ERROR 42Y03: 'RAND' is not recognized as a function or procedure.

RAND is a broken function that takes an INTEGER seed parameter. It's to match the JDBC escaped
function spec but it's broken because it will always return the same value for a given seed.
