Subject Re: Error when testing dates
Date Wed, 04 Jul 2012 19:36:55 GMT
So I changed query to be the following:
(xs:date("2004-12-25Z") eq xs:date("2004-12-25+07:00"))

Still does not work. Does the system know how to read the date field?

Plan:
write [%0->$$6] -- |UNPARTITIONED|
  unnest $$6 <- function-call:
vxquery:{urn:org.apache.vxquery.operators-ext}iterate, Args:[%0->$$5] --
|UNPARTITIONED|
    assign [$$5] <- [function-call:
vxquery:{urn:org.apache.vxquery.operators-ext}value-eq,
Args:[function-call: vxquery:{urn:org.apache.vxquery.operators-ext}promote,
Args:[function-call: vxquery:{http://www.w3.org/2005/xpath-functions}data,
Args:[%0->$$2], {http://www.w3.org/2001/XMLSchema}int QUANT_ONE(bytes[5] =
[1d00000002])], function-call:
