Alzabo::Create::ColumnDefinition - Column definition object for schema creation
This object holds information on a column that might need to be shared with another column. The reason this class exists is that if a column is a key in two or more tables, then some of the information related to that column should change automatically in multiple places whenever it changes at all. Right now this is only type ('VARCHAR', 'NUMBER', etc) information. This object also has an 'owner', which is the column which created it.
Note: all relevant documentation from the superclass has been merged into this document.
This method allows you to change a column's type, length, and
precision as a single operation and should be instead of calling
set_type followed by
