Columns

module: pyrseas.dbobject.column

The column module defines two classes, Column derived from DbSchemaObject and ColumnDict, derived from DbObjectDict.

Column

Column is derived from ~pyrseas.dbobject.DbSchemaObject and represents a column in a table, or an attribute in a composite type. Its keylist attributes are the schema name and the table name.

A Column has the following attributes: name, type, not_null and default. The number attribute is also present but is not made visible externally.
