Chunwei Lei commented on CALCITE-2965:
--------------------------------------
{quote}SOUNDEX is not in the SQL standard and it's not – I hope you will agree
– a very important function. So I don't think we should elevate it to a
standard function.
{quote}
It is fine with me.
{quote}Have we figured out where to put such functions? SqlStdOperatorTable
seems to be the wrong place, and OracleSqlOperatorTable seems to be the wrong
place also (if it means duplicate code with MysqlSqlOperatorTable).
{quote}
I am afraid not. Should we discuss how to deal with it in CALCITE-2846 since
there is already quite a little discussion?
