> The server returns scale value of -1 for this query
> select cast('999999999999999999' as decimal(18,0)) + cast('9999999999999999999999999999999999999' as decimal(38,0)) from (values(1))
>
> The getValueAt() function did not take into account of the possibility of -1 scale and will go into infinite loop of appending 0 to the string buffer.
