-406 A CALCULATED OR DERIVED NUMERIC VALUE IS NOT WITHIN THE RANGE OF ITS OBJECT COLUMN

Explanation
  A value derived or calculated during
processing of the SQL statement was outside the range of the data
type of its object column. This problem might have arisen for one
of the following reasons: The values occurring in the object column were out of range.
The SQL operation performed was not appropriate for the values
in the object column.
A DECIMAL(19,0) column is altered to BIGINT, but a value in the
column is outside the range of BIGINT.

System action
  The statement cannot be processed.

Programmer response
  See the explanation of SQLCODE -405 for
allowed ranges for numeric data types.

 If the error occurred while accessing a table column
that was altered from DECIMAL(19,0) to BIGINT, alter the column data
type back to DECIMAL(19,0) and refer description of the ALTER TABLE
statement for information about how to change DECIMAL(19,0) columns
to BIGINT.
