-------------------------------------

Yes ,im sure the jdbc adapter will occur the error,when you define a column 
with datatype: int(10) unsigned 
it will  be mapped with RelDatatype of Integer
than the jdbc driver will do some thing like Integer.parseInt(3729727635)

> JdbcAdapter will "NumberOutOfRange" when iterating over the datetime column 
> of mysql with function application

> When I have a mysql table, the example is as follows:

> |1|2021-08-11 14:38:01.0|3729727635|
>  
> it will be OK:
> {{select gettime from table}}
>  
> it will occor some error:
