> Hi,
> When performing the following code:
> {{select cast(7.415246799222789E19 as int)}}
> according to the documentation, an error is expected as
> {{7.415246799222789E19 }}is an overflow value for datatype INT.
> However, the value 2147483647 is returned.
> The behaviour of the following is correct as it returns NULL:
> {{select try_cast(7.415246799222789E19 as int) }}
> This results in unexpected behaviour and data corruption.
