remove_column(table_name, column_name, type = nil, options = {}) public

Removes the column from the table definition.

remove_column(:suppliers, :qualification)

The type and options parameters will be ignored if present. It can be helpful to provide these in a migration’s change method so it can be reverted. In that case, type and options will be used by #add_column. Indexes on the column are automatically removed.
