Subject [Db-derby Wiki] Update of "ReferenceManualTenTwo" by DanDebrunner
Date Tue, 29 Aug 2006 13:47:18 GMT
Dear Wiki user,

You have subscribed to a wiki page or wiki category on "Db-derby Wiki" for change notification.

The following page has been changed by DanDebrunner:
http://wiki.apache.org/db-derby/ReferenceManualTenTwo

------------------------------------------------------------------------------
  ||CEIL Function || [http://db.apache.org/derby/docs/dev/ref/rreffuncceil.html HTML URL]
|| Susan  || According to DERBY-1548, Derby does not support negative zero, so this statement
'If the specified number is less than zero but greater than -1.0, then the result of these
functions is negative zero.' should be changed to this 'If the specified number is less than
zero but greater than -1.0, then the result of these functions is zero.'  ||
  ||JDBC Escape Syntax - PI Function || [http://db.apache.org/derby/docs/dev/ref/rrefjdbc88908.html
HTML URL] || Susan  || I think this is a typo - 'Returns an value that is closer than any
other value to pi.'  I believe this is correct, 'Returns a value that is closer than any other
value to pi.'  ||
  ||List of datatypes || http://db.apache.org/derby/docs/dev/ref/ || Dan D || In the list
of data types the XML type is listed as 'XML data type', remove the words 'data type', all
of the other types are listed just as the type name. Same is true of the page that describes
the XML type, it says 'XML data type', other types just have the name of the type, e.g. BLOB
||
+ || XQUERY operator || docs/html/ref/rreffuncxmlquery.html || Dan D || This description:
''The result of the XMLQUERY operator is another Derby XML value. Unlike other XML values,
the result might represent an empty sequence of XML nodes or values. Atomic values, such as
strings, can be part of the result sequence. The result of an XMLQUERY operator is not guaranteed
to represent a valid XML document and it might not be possible to insert the result of an
XMLQUERY operator into a Derby XML column'' should be replaced with: The result of the XMLQUERY
operator is '''a value of type XML'''. '''The result represents a''' sequence of XML nodes
or values. Atomic values, such as strings, can be part of the result sequence. The result
of an XMLQUERY operator is not guaranteed to represent a '''well formed''' XML document and
it might not be possible to insert the result of an XMLQUERY operator into an XML column 
- Notes on the changes (bold), a) no need to use Derby b) The old word
 ing had the use of 'might' and 'empty sequence', I think it wanted to describe a sequence
and the result is always a sequence, not that it might be. c) Use of 'well-formed' is better
than 'valid'. ||
