将Oracle SQL转换为HANA SQL

Question

I have a where condition in oracle SQL 11g which I want to use in SAP HANA SQL : Oracle SQL query :

NOT  REGEXP_LIKE (UPPER(substr(GEN_ID,4,5)), '[A-Z]')

I have tried using like_regexp but unable to fetch records.

NOT  REGEXP_LIKE (UPPER(substr(GEN_ID,4,5)), '[A-Z]')

I am expecting the regexp_like to work same in HANA

Answer 1

试试LIKE_REGEXPR

UPPER(substring(GEN_ID,4,5)) LIKE_REGEXPR  '[A-Z]'

Answer 2

In either database, I think I would phrase this as:

GEN_ID LIKE_REGEXP '^.{3}[^A-Za-z]{5}'

I find that doing part of the string matching using substrings and not and part using regular expressions is more complicated than necessary.
