Initcap of word

I’m having a table x it contain the column resource_name in this column I’m having data like NASRI(SRI). I’m applying initcap on this column it’s giving output Nasri(sri). But my expected output is Nasri(Sri). How I can achieve the desired result?

Thank you

Answer

One possible solution is to use split() with concat_ws(). If value does not contain ‘()’, then it will also work correctly. Demo with ():

hive> select  concat_ws('(',initcap(split('NASRI(SRI)','\(')[0]), 
                            initcap(split('NASRI(SRI)','\(')[1])
                       );
OK
Nasri(Sri)
Time taken: 0.974 seconds, Fetched: 1 row(s)

And for value without () it also works good:

hive> select concat_ws('(',initcap(split('NASRI','\(')[0]),
                           initcap(split('NASRI','\(')[1])
                      );
OK
Nasri
