I want to merge features by attribute that contains string from target attribute.
FeatureMerger does job done but only in case where attribute(req) = attribute(sup). In my case i want to expression to loke like this attribute(req) CONTAINS attribute(sup).
Have a look at this similar post:

Basically just expand the wildcard to something like
select *
from table_a join table_b on '%' || table_a.id || '%' like '%' || table_b.id || '%'Just be aware that matching on substrings is relatively slow.

Thank You
+7Another question that might be solved by implementing string functions and regex!

+1I had similar requirement. Solved using Inlinequerier
Sample below joins table SAP To LOC, where SAP.MatchedPlatform is a sub string in LOC.LOC_OTH_NAME_MATCH
creates
SELECT * FROM SAP LEFT JOIN LOC ON INSTR(LOC.LOC_OTH_NAME_MATCH, SAP.MatchedPlatform) > 0
Hope this helps
