# Strict mode controls how MySQL handles invalid or missing values
# in data-change statements such as INSERT or UPDATE. A value can be
# invalid for several reasons. For example, it might have the wrong
# data type for the column, or it might be out of range. A value is
# missing when a new row to be inserted does not contain a value for
# a non-NULL column that has no explicit DEFAULT clause in its definition.
# (For a NULL column, NULL is inserted if the value is missing.)
#
# If strict mode is not in effect, MySQL inserts adjusted values for
# invalid or missing values and produces warnings. In strict mode,
# you can produce this behavior by using INSERT IGNORE or UPDATE IGNORE.
