[jira] Updated: (DERBY-4106) The Reference Gulde claims that the INTEGER function can be applied to dates and times

     [ https://issues.apache.org/jira/browse/DERBY-4106?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Bryan Pendleton updated DERBY-4106:
-----------------------------------

    Attachment: rrefbuiltinteger.html
                docs.diff

I removed the reference to date and time in the attached patch proposal.

I checked the manual pages for SMALLINT and BIGINT and observed that
they were correct, and made INTEGER follow their pattern.

I checked that CastingTest.java in the lang suite already verifies
the behavior of the INTEGER function, so no new tests are needed.

This seems like a straightforward fix to the docs.

> When Derby Reference Manual, version 10.4, explains the INTEGER function is said that:
>  "The INTEGER function returns an integer representation of a number, character string,
> DATE, or time in the form of an integer constant"
> But when I try to convert a DATE to INTEGER I receive an sqlstate 42846: "Cannot convert types 'DATE'  to 'INTEGER'."
> This is a sample query where the expected result is the integer number 1: 
> select integer(date(1)) from SYSIBM.SYSDUMMY1
