I have this complicated SQL query for Oracle that I want to visualize in a diagram to make it understandable for my co-workers. I tried at http://snowflakejoins.com but it just chokes on it.
Has someone a better suggestion? I prefer a web-app on the internet and if not a desktop app for windows.
with
logs as (
select
l.job_id,
l.subjob,
sum(l.verwerkt) verwerkt,
sum(l.errors) errors,
max(l.datum) laatst
from
dinf_monitor_logs l,
dinf_monitor_jobs j
where
l.datum>sysdate-j.dagen
and j.job_id=l.job_id(+)
group by
l.job_id,
l.subjob
),
alllogs as (
select job_id, subjob, max(datum) laatst from dinf_monitor_logs group by job_id, subjob
)
select row_number() over(order by alllogs.job_id, alllogs.subjob) r,
alllogs.job_id,
alljobs.naam,
alllogs.subjob,
logs.verwerkt,
logs.errors,
alllogs.laatst datum,
alljobs.wikilink,
alljobs.loglink,
alljobs.contact,

when alllogs.laatst is null then 1
when round(sysdate-(alllogs.laatst+alljobs.dagen))<0 then 0
else round(sysdate-(alllogs.laatst+alljobs.dagen))

when logs.errors-alljobs.max_errors>0 then 5
when logs.verwerkt-alljobs.min_verwerkt<0 then 7

Answer 1

You can use the "Query Builder" tab of the Oracle's SQL Developer.
The result of your sample query will be:

Answer 2

Each of the sub queries are data sets, I would just make a plain English statement of what the query does, then describe the data sets and how they relate to one another in an entity-relationship manner, then show how the query satisfies the plain English statement. You can represent the E-R with any variety of tools.

Answer 3

Have found how to do it in Toad, which i prefer above Sql Developer.
Open the editorwindow, paste the sql, rightclick in the editorwindow and select "Send to queryviewer"
My sql above is too complicated to use this technique but it's nice to know i can use it in the future with more "normal" queries.
