> In Hive "select translate(name, 'A', 'B') from users" works fine.
> But in Drill "select translate(name, 'A', 'B') from hive.`users`" returns the
> following error:
> org.apache.drill.common.exceptions.UserRemoteException: PARSE ERROR:
> Encountered "," at line 1, column 22. Was expecting one of: "USING" ... "NOT"
> ... "IN" ... "BETWEEN" ... "LIKE" ... "SIMILAR" ... "=" ... ">" ... "<" ...
> "<=" ... ">=" ... "<>" ... "+" ... "-" ... "*" ... "/" ... "||" ... "AND" ...
> "OR" ... "IS" ... "MEMBER" ... "SUBMULTISET" ... "MULTISET" ... "[" ... "."
> ... "(" ... while parsing SQL query: select translate(name, 'A', 'B') from
> hive.users ^ [Error Id: ba21956b-3285-4544-b3b2-fab68b95be1f on
> localhost:31010]
> Root cause:
> Calcite follows the standard SQL reference.
> SQL reference, ISO/IEC 9075-2:2011(E), section 6.30
> <character transliteration> ::=
> TRANSLATE <left paren> <character value expression>
> USING <transliteration name> <right paren>
> To fix:
> 1. add support to translate (expession, from_string, to_string) alternative
> syntax
> 2. add unit test in org.apache.drill.exec.fn.hive.TestInbuiltHiveUDFs
> Changes can be made directly in Calcite and then upgrade to appropriate
> Calcite version.
