Zhixiong Chen updated CALCITE-3899:
-----------------------------------
Description:
sql like::
SELECT cast( ? as date)
FROM
Table group by cast( ? as date)
the dynamic parameter is string like '2020-04-07'
But it throw exception like java.lang.String cannot be cast to
java.lang.Integer
then I find in calcite plan it will cast string as integer and throw exception
/* 22 */ public Object current()
{ /* 23 */ return (Integer) root.get("?0"); /* 24 */ }
