How to filter out specific rows in a table based on column values?

[parizanov]

Hello,

I have a table like the one below, with a column containing repeated id numbers form one side and respective messages for each id on the other side. I want to make a search which can show the id numbers that have only "Error" message as value and skip repeating ids that have Error and OK. Any help is much appreciated.

col1       col2
11111      Error
11111      OK
55555      Error

In the example, successful query should return 55555.

Try this

base search | chart count over col1 by col2 | where col2=0

*OR*

base search | eventstats values(col2) as status by col1 | where isnull(mvfind(status, "OK"))
