BLOB

Synopsis

BLOB[(width)]

This column data type allows for the storage of a large amount of binary data. You may give a width with this data type; the maximum is 65,535 bytes. If you attempt to store a value in a BLOB column that is larger than its limit, unless the server is set to SQL strict mode, the data will be truncated and a warning message will be generated. If strict mode is on, the data will be rejected and an error will be returned. A BLOB column cannot have a default value. For sorting data, the value given for the system variable max_sort_length will be used. Only the number of bytes specified by that variable for each column will be included in sorts.
