Remove leading zeros using HiveQL



I have a string value in which i might have leading zero's, so i want to remove all leading zeros.



For example:


accNumber = "000340" ---> "340"



Any UDF is available in Hive? can we use regexp_extract for this?


regexp_extract

Yes, just use REGEXP_REPLACE().


REGEXP_REPLACE()


SELECT some_string,
REGEXP_REPLACE(some_string, "^0+", '') stripped_string
FROM db.tbl



(fixed simple typo with comma)





didn't know it. Thanks

No <tab> before $(info ...) neither, this is make – Zelnes ...
