One way to approach such a problem is what I just did:
- Google "sql vowel" and find http://stackoverflow.com/questions/13753498/select-vowels-from-a-varchar-oracle-pl-sql
- Look up REGEX functions in the SAP HANA documentation and find OCCURRENCES_REGEXPR - SAP HANA SQL and System Views Reference - SAP Library
- Fiddle a bit with it to come up with a query that counts vowels for one column
select user_name,
OCCURRENCES_REGEXPR ( '[aeiou]' FLAG 'i' in user_name) as VOWEL_COUNT
from public.users;
| USER_NAME | VOWEL_COUNT |
| SYS | 0 |
| SYSTEM | 1 |
| _SYS_STATISTICS | 3 |
| _SYS_EPM | 1 |
| _SYS_REPO | 2 |
| _SYS_AFL | 1 |
| DEVDUDE | 3 |
| ADMIN | 2 |
| PUBLICJOE | 4 |
| DEDUDE | 3 |
| JDBCDUDE | 2 |
| OZDUDE | 3 |
| _SYS_TASK | 1 |
| _SYS_XB | 0 |
From here it's trivial to come to a combined firstname/lastname vowel count.
