This seems to be one thing java has over php (perl etc) as it does know
about the warning and acts approperately. This should be an option to
ignore or not ignore warnings within php to prevent errorless truncation

It seems that the normal mysql_query doesn't error when an sql command
forces the server to truncate the data. The mysql server executes the
sql and provides a warning but it still executes the sql so allowing php
to ignore the fact that there is a warning. You can run another sql
command "SHOW COUNT(*) WARNINGS" after your insert command to check if
there is a warning and roll back the changes - similar to the java mysql
interface. I haven't used mysqli and perhaps this is addressed in that ?
I doubt it.
Using sqlyog (3rd party mysql gui) to run the sql also provides no
warning message but running it on the command line provides the "1 row
affected, 1 warning message" With data validation and check this data
too large situation should never happen but surely php should pay
attention to the warnings too ?
It's not a php problem. Mysql should throw proper errors instead of a 'warning'.
If you assign a value to a BLOB or TEXT column that exceeds the data
type's maximum length, the value is truncated to fit and a warning is
Same for char/varchar & binary fields
You will get the same "problem" in other languages I'm sure (try it in
python, perl, ruby).
