MarkLogic 9 Product Documentationdbg:stop
dbg:stop() as empty-sequence()
Summary
Placing this call in XQuery will instruct the evaluator to stop a request for debugging.
Usage Notes
Callingdbg:stop stops the request immediately, and therefore
if there are any expressions after the call they will not be evaluated until
you call another debug function that accesses the stopped query and makes
the debuging commence (dbg:continue or dbg:step,
for example). Before you commence debugging a stopped query, it will
appear to be hung (because it is stopped).
Example
dbg:stop() => ()
Example
(: first run this in one request :)
"hello", dbg:stop(), xdmp:log("look in app error log")
(:
It will stop at the dbg:stop.
Next run the following (in another request, from another instance
of Query Console if you are using Query Console).
:)
dbg:continue(dbg:stopped()[1])
(:
Look in app error log for the log message, and look at the original
query to see it returned "hello".
