Accessing an element in an Array and ArrayList [message #682254]

I have over 100k Object[] records.

Say the Object[] is like this. {"Name", "Value"}

I want to figure out the instances of Object[] with a particular value

Something like Select * from Object[] where Object[1] = "Value"

Please suggest a way to achieve it using the Analyzer or OQL.

Thank You

This is a bit complicated, but something like:

SELECT * FROM java.lang.Object[] s WHERE ((s.@length >= 2) and (s.@referenceArray.get(1) != 0) and (toString(${snapshot}.getObject(${snapshot}.mapAddressToId(s.@referenceArray.get(1)))) = "Value"))

should work.

This finds all the Object arrays then selects those where the length is at least 2, and with element at index 1 not null, and where the element at index 1 as an object address is converted to an MAT object ID, then to an MAT IObject, then converted to a string using an MAT name resolver, then tested against "Value".

Bug 287268 can be used to track ideas for improvements.
