We are also working on some extensions to solve this problem for some
common application niches.
MySQL can work with both transactional and not transactional tables. To
be able to work smoothly with not transactional tables (which can't
rollback if something goes wrong), MySQL has the following rules:
@cindex default values
@itemize @bullet
@item
All columns has default values.
@item
If you insert a 'wrong' value in a column like a @code{NULL} in a
@code{NOT NULL} column or a too big numerical value in a numerical
column, MySQL will instead of giving an error instead set the column to
the 'best possible value'. For numerical values this is 0, the smallest
possible values or the largest possible value. For strings this is
either the empty string or the longest possible string that can be in
the column.
@item
All calculated expressions returns a value that can be used instead of
signaling an error condition. For example 1/0 returns @code{NULL}
@end itemize
The reason for the above rules is that we can't check these conditions
before the query starts to execute. If we encounter a problem after
updating a few rows, we can't just rollback as the table type may not
support this. We can't stop because in that case the update would be
'half done' which is probably the worst possible scenario. In this case
it's better to 'do the best you can' and then continue as if nothing
happened.
The above means that one should not use MySQL to check fields content,
but one should do this in the application.

@cindex default values
Any column not explicitly given a value is set to its default value. For

assignment is described in @ref{CREATE TABLE, , @code{CREATE TABLE}}.
MySQL always has a default value for all fields. This is something
that is imposed on MySQL to be able to work with both transactional
and not transactional tables.
Our view is that checking of fields content should be done in the
application and not in the database server.
