Mysql change column's default value

Code:
mysql> ALTER TABLE table_name MODIFY column_name INT DEFAULT 'some default value';


Remember that column type must be a char, varchar, enum or some other column type that supports default value. TEXT/BLOB columns do NOT support default values.

If an attempt to set a text column's default value a mysql error will be produced:
Quote:
ERROR 1101 (42000): BLOB/TEXT column 'preferences' can't have a default value
