You can disable STRICT_TRANS_TABLES
and STRICT_ALL_TABLES
. This allows the automatic truncation of the inserted string.
Quote from MySQL Documentation.
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.)
