Select only words with capitals

Question

If I have data stored in my Database much like this Sentence, with Some words containing uppercase letters and some not, what is the simplest Way to select only those words which contain upperCase letters?
From the above sentence, for example, I would want to see the result :
If I Database Sentence Some Way upperCase
Note that the uppercase letter(s) will not always be at the start of a word.
Is there a simple way to achieve this? I started dabbling with REGEXP_LIKE, but my regular expressions are pretty hopeless at the best of times :-(

Answer 1

I've seen more regular expression syntax explanation documents in my time than you've had hot dinners, probably. I'm afraid I still plead complete ignorance and find constructing anything other than the very simplest incredibly difficult, even with the help of various freebie utilities and tools you can download to help you do the job. It's a blind spot I have, and it's not going away any time soon. So yes, I have seen before at least the first of those pages you linked to, but I can't say it's helped me much.
For the rest, I gave an example of the input and output I'd like to achieve. Your suggestion regarding the lastname column from the EMP table doesn't help in that regard, and even when I translate it into something approaching my actual situation, it doesn't do what I need it to do:
create table test_t1 (col1 varchar2(4000));
insert into test_t1 values ('If I have data stored in my Database much like this Sentence, with Some words containing uppercase letters and some not, what is the simplest Way to select only those words which contain upperCase letters?');
commit;
SQL> select * from test_t1 where col1 like '^[A-Z]%';
no rows selectedAlso, you've apparently used the "^" character to indicate that it's the beginning of the string that should be checked for containing an uppercase character, but as I mentioned, my uppercase characters can appear anywhere within the string.
Anyone else, please?
