Answer 1

hi
we can use a model clause....
I remember someone using model clause in this way.....but not able to get that post....took sometime to construct it.
with tab as (
select 'AİIB BBB CCC. DİDDD EEEE.' col from dual
select col,newcol from
tab
model
partition by (rownum rnum)
dimension by (0 dim)
measures(col, cast(null as varchar2(4000)) word,cast(null as varchar2(4000)) newcol)
rules iterate (1000) UNTIL (word[0] IS NULL)
  word[0] = REGEXP_SUBSTR(col[0], '[^.]+', 1, ITERATION_NUMBER + 1),
  newcol[0] = case when ITERATION_NUMBER =0
                    then
                      newcol[0]||regexp_substr(word[0],'[[:space:]]*[[:alpha:]]',1,1)||lower(regexp_substr(ltrim(word[0]),'([[:alpha:]]|[[:space:]])+',2,1))
                    else
                      newcol[0]||'.'||regexp_substr(word[0],'[[:space:]]*[[:alpha:]]',1,1)||lower(regexp_substr(ltrim(word[0]),'([[:alpha:]]|[[:space:]])+',2,1)) end
)If your logic is such that names are separated by fullstop and first letter of each name is capital and others to be small then above logic works.
