If you specify the true or false functions inside the exist method, the exist method will return 1, because the functions true and false return Boolean True and False, respectively. That is, they return a nonempty result. Therefore, exist will return 1 True , as shown in the following example:. In the following example, x is an xml type variable untyped xml and f is an integer type variable that stores the value returned by the exist method.
The exist method returns True 1 if the date value stored in the XML instance is The code cast as xs:date?
The value of the Somedate attribute is untyped. In comparing this value, it is implicitly cast to the type on the right side of the comparison, the xs:date type. Instead of cast as xs:date , you can use the xs:date constructor function. Please guide me to solve the issue below I want to return the null value as a string, if the below expression does not give any value.
Currently, the output doesn't show the 'name' field itself. I want to have a name with null. You could use the fn:exists function to test whether or not there is a text node. You could also use the fn:boolean function to test the effective boolean value of the node.
If you wanted to test whether or not there was a significant value i. XQuery doesn't have null , so if you are asking what to return to indicate null , then you would want to return an empty sequence instead of null. But at that point, it's really the same as just attempting to select the text with that XPath and it will either return the text node or an empty sequence:.

Your idea of flowing a value into ILM is a good one, and if you're in a position to do that then I would do so. If you're not, as I'm not in a couple of cases at the moment, you have to use the NOT operator and either follow Ahmad's advice opposite sets or just go ahead and utilise NOT as I mentioned above.
Ultimately we all know that NOT is expensive. It's just a matter of weighing up whether or not it's appropriate to utilise. As I'm sure you know from experience, many times it is, as long as we don't get carried away.
Coming back to your direct question re. I've found this helpful in debugging. Access denied doesn't necessarily mean lack of permissions. It also means AuthZ has failed, and AuthZ WF might have nothing to do with permissions but could be a validation activity.
Following the URLs in the applied policies section to the different MPRs and then WFs as an administrative user has helped me get to the bottom of several things. When this has failed I've enabled tracing and stared at the trace for sometime before guessing what might be wrong I think Brad confused your initial post with my example, which utilises a custom attribute.
No worries, just ignore. When I first implemented my custom attributes I got access denied for the exact reason cited by Brad. I resolved this issue by following the applied MPRs as mentioned above and reaslised there was an object behind the WF that was causing the AuthZ action to fail. Once I'd fixed this and written a draft blog entry I found Brad's helpful post!
Or even something wild like Failing is just silly. Hi Nina, Thanks for the information. I do have one clarification though. This does not work anymore If it ever did:. Wednesday, November 16, AM.
