Subject Re: WHERE clause with nested JSON data
Date Tue, 31 Mar 2015 15:27:49 GMT
Are there any null values?

Perhaps try to filter out null values (if there are any) and then see if it succeeds.

Select <….> from …. t where t.json.runtimeConfiguration.properties.jvmHeapUsageInit
is not null and t.json.runtimeConfiguration.properties.jvmHeapUsageInit >3000

In some cases I found that for the most reliable results to use a subquery to filter out nulls
and then apply the main query.
