MySQL too long varchar truncation/error setting

Question

I have two MySQL instances. The 1st one truncates strings on insert when data is too long. The 2nd one raises an error:

ERROR 1406 (22001): Data too long for c

Answer 1

replace

sql-mode="NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION"

into /usr/my.cnf

to

sql-mode=""

run

/etc/init.d/mysql restart
