what happens when you write X'4040' to a DDL numeric field?
If the SQL DDL that described the "numeric field" had defined that
numeric field as either data-type NUMERIC or DECIMAL, then...
The data is not written to the file, due to a data mapping error;
e.g. a CPF5035 followed by a CPF5029. The mapping error is manifest in
the HLL according to the rules of that language, and the instruction,
statement, or opcode[+extender] that requested the output operation.
If instead the data type had been defined as any form of INTEGER
[i.e. also SMALLINT or BIGINT], then...
The data would get written and there would be no error, because every
possible bit pattern is valid for an integer data-type.
If the data type was FLOAT, who cares ;-) and if DECFLOAT I really do
not know enough to comment.
