>          Issue Type: Umbrella
>          Components: SQL

> Create new safe version SQL functions for existing SQL functions/operators, which returns NULL if overflow/error occurs. So that:
> 1. Users can manage to finish queries without interruptions
> 2. The result can be more reasonable. For example, the result of the following operation is terrible
> {code:java}
> 2147483647 + 2 => -2147483647
> CAST(2147483648L AS INT) => -2147483648
> {code}
> Having the safe version SQL functions provides an alternative solution for handling such cases
> {code:java}
> TRY_ADD(2147483647, 2) => null
> TRY_CAST(2147483648L AS INT) => null
> {code}
