Detailed Description

Represents a column definition in a CREATE/ALTER TABLE/VIEW statement. Column definitions in CREATE/ALTER TABLE statements require a column type, whereas column definitions in CREATE/ALTER VIEW statements infer the column type from the corresponding view definition. All column definitions have an optional comment. Since a column definition refers a column stored in the Metastore, the column name must be valid according to the Metastore's rules (see ).
