FWIW? Naturally I followed that link, but was unable to understand (or piece together) the information there in. Storage Requirements for String Types: (or maximum length of BLOB types for dummies) TINYBLOB (or TINYTEXT) = 1+(2^ 8) = 257 characters BLOB (or TEXT) = 2+(2^16) = 65538 characters MEDIUMBLOB (or MEDIUMTEXT) = 3+(2^24) = 16777219 characters LONGBLOB (or LONGTEXT) = 4+(2^32) = 4294967300 characters Does that answer my question? I think it does, but I am not sure. Seems strange not to have this information at the very begining of the cited page. -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe: http://lists.mysql.com/[EMAIL PROTECTED]
