Julian Hyde commented on CALCITE-3522:
--------------------------------------
I don't think you can just remove the checks. If you do that then some
implementations (e.g. those that map DECIMAL values to 64-bit scaled integers)
will give incorrect results.
> sql validator limits decimal literals to 64 bits

> for example:
> create table tbl(f1 double),
> f1 stores a double's max value. (1.7976931348623157E308)
> long max value is 9223372036854775807.
> select * from table where f1=value, if value is greater than long max,
> sqlvalidator will throw out of range exception.
