SQL0802N  Arithmetic overflow or other arithmetic exception occurred.

Explanation:

The processing of a column function or arithmetic expression has
resulted in an arithmetic overflow.

The statement cannot be processed. For the INSERT, UPDATE, or DELETE
statements, no inserts or updates are performed.

User response:

Examine the SQL statement to determine the cause of the problem. If the
problem is data dependent, it is necessary to examine the data processed
when the error occurred. Refer to the SQL Reference to see the valid
ranges for the data types.

This error may also be returned when column functions cannot handle the
value that is returned by the SQL statement. For example, issuing a
SELECT COUNT statement against a table that has more rows than defined
by the MAX_LONGINT_INT SQL limit will cause an arithmetic overflow
error. Consider using the COUNT_BIG column function for tables with more
than 2 147 483 647 rows.

Federated system users: examine the SQL statement to determine the cause
of the problem. If the problem is data dependent, examine the data being
processed at the data sources when the error occurred. Refer to the
corresponding SQL Reference for the data source to determine the valid
ranges for the data types.
