A Binary Large OBject (BLOB) is a varying-length string measured in bytes that can be up to 2 gigabytes (2 147 483 647 bytes) long. A BLOB is primarily intended to hold non-traditional data such as pictures, voice, and mixed media. Another use is to hold structured data for exploitation by user-defined types and user-defined functions. As with FOR BIT DATA character strings, BLOB strings are not associated with a character set.
