Hi Craig, thanks, yes i know i could have combined my query into one but
this was just to split things out. Its only purpose was to create the
initial subset of the bigger graph that would be input for the actual
query.. I tried your query but it does not give any results back but with
some help
Hi, this seems to work (with file:/// .. i.e 3 slashed) although i assumed
that the file location could be relative to the import directory and i did
not get a file not found error .. anyways .. thanks !

Hi kamal this works fine and i included it into my overall query thanks.
So my final question on this would be
1) how to know that you have to put " " around the query part of the
query following the condition ?
2) how do you know that the syntax of "param" is like{w:w} ...
orby som
Hi Kamal, thanks, i have seen this "construct" before and will test it.
However i am still very interested to learn how to use the call
apoc.do.case() procedure to implement this .. i expect that the result
might look somewhat more straightforward (to say the least) i.. and ideas
how to apply tha
Hi kamal. thanks, thats also how i do it now.
Maybe one other question to the community
Is there an example of a cypher query using a *call apoc.do.case()*
procedure where you want to have multiple "condition,query" pairs and where
each "query" performs multiple operations such as a property SET
H kamal thanks, that works too. i guess the original problem was due to the
"call" statement being there .. removing that seems to work although i
thought i tested that already .. it also needed small rewrite to SET the
uuid property to avoid duplicate record conflicts
so for apoc functions no cal
thanks michael
i copied a database from the 3.3 community edition across so that might be
the reason.
#2 was more kind of suggestion to automate the update of the conf file if
you download the plugin library.. but i already did it manually

Hi andy, i am already using the merge command which works fine to create
unique records but i also want to be able to for example update / change an
attribute on an existing node .. i maybe have to do some more testing with
all merge options ..

Yes, unfortunately not all links point to that location... so why not
simply include the latest working version of the apoc library in the build
that can be downloaded from the neo4j website ?

actually i asked the same question in a somewhat different manner a few
weeks ago... i.e. to replace relations through intermediate nodes
representing the relation to allow for inclusion of the time based
dimension.. the question was if there is experiemce out there doing this
for bigegr graphs ..
hi, one advantage of an extra hop that represents the "event" of one user
following the other can be the fact that you can now link that "follow"
node/event to a timeline graph node which allows for time based traversal
.. and see what happened at some point in time.. who followed who .. when
.. e
it is more the structure your query than the amount of nodes

the query looks pretty straightforward but i am no expert
you could try to gradually increase to see when issues arise. 1..2 1..3
1..4 1..5 etc . and whatif you use the shortestpath function

hi, sure.. actually i would like to build a kind of report that reflects
the amount of paths found for a specific relstype (REL1) between each 2
nodes (actully this means duplicate paths if more than 1 found) , their
length, the shortest based on weight, and whether there is at least also
one p
hi thx, that one works (just tested it) :
match p=(n:label1)-[:REL1*]->(m:label2)
where NOT (n)-[:REL2*]->(m)
return p
any other syntax ideas ?
ps .. i was thing far more complex withdual match ... with to pass data
to the secondary match ... and some functions to compare the 2 sets ...
35 matches
