Hi,

Per the documentation, "This function is only available for use within SQL; it 
is not available directly from XQuery, XSLT, or JavaScript." - 
https://docs.marklogic.com/sql:dateadd

The equivalent operation to your example in xQuery is:

xs:dateTime('2008-11-11T13:23:44.657') + xs:dayTimeDuration('P45D')

Best,
Rob

Subject: [MarkLogic Dev General] sql:dateadd function
Hi All,

I have a use case where I need to add a  day to a given dateTime variable.  I 
would like to use the sql:dateadd function to do this.
However, when I try to run it in Query Console I get an error:
[1.0-ml] XDMP-UNDFUN: (err:XPST0017) Undefined function sql:dateadd()
Here is the code I am running in Query Console.

xquery version "1.0-ml";
declare namespace html = "http://www.w3.org/1999/xhtml";;
declare namespace sql = "http://marklogic.com/xdmp/sql";;

sql:dateadd('day',45, '2008-11-11T13:23:44.657')

It's not finding the function, but I am not clear on how to reference it.

Thanks,

Javier
