Subj:   Re: Numeric overflow when inserting
 
From:   Michael McIntire

When I run into these overflows, I write a query that casts to float and then tests for a value greater than the width of the native type or some threshold value:

Select sum( cast(smallint_col as float) ) as sint_sum
        ,sum( cast(dec_col as float) ) as dec_sum
        ,sum( cast(int_col as float) ) as int_sum
        ,case when sum( cast(smallint_col as float) ) GT 32000 then
'true' else ' ';
        ,case when sum( cast(dec_col as float) ) GT 9999999999999999
then 'true' else ' '
        ,case when sum( cast(int_col as float) ) GT 23000000 then 'true'
else ' ' From problem_table;

And unfortunately, you cannot tell from the ODBC error which column is the issue.
