Hi,

I have two indexes:
index="abc"

index="dummy"

Now both indexes have one common field ID.

I want to compare index dummy with index abc and list all IDs which are present in index abc, but not in index dummy

eg

index=abc contains

id
2
4
6
8
10

index=dummy contains
1
2
3
4
5
6
7
10

desired result
8

Thanks

Try this

Updated wrong function used in where.

index=abc OR index=dummy | stats values(index) as index by ID | where mvcount(index)=1 AND index="abc"

Update2
For dbquery

index=abc | table ID | eval From="abc" | append [| dbquery ...your query | table ID | eval From="dbquery" ]  | stats values(From) as From by ID | where mvcount(From)=1 AND From="abc"

What's the error do you get? Do the queries work individually?
