And your question is? :)

The reason for this is that your field is defined as NUMERIC(18,n) where n >
0. This reduces the maximum possible value, since the fixed-point numbers
are stored in the scaled format and the decimal places must be specified
too. In case of Long.MAX_VALUE, which is already 19 digits long, you require
Firebird to add n zero digits according to the column definition - that
simply is greater than maximum possible numeric value that can be sent to
Firebird over the wire. The only fix to this situation is to use the BIGINT
column (or don't use Long.MAX_VALUE, take something smaller).
