WL#6385: Define and Implement API for Schema
Affects: Server-8.0 — Status: Complete — Priority: Medium
This worklog specifies interfaces of the following object types: - Charset - Collation - Schema For the framework class definitions see WL#7284.
NOTE: lookup() operations return a valid object pointer if object was found, or NULL otherwise. Charset ======= The interface provides read-only accessors, as the character set / collation features are defined outside the Data Dictionary and might not be changed by the Data Dictionary customers. Attributes ---------- - read-only default_collation attribute -- a reference to the default collation implied by a character set. - read-only mb_max_length - comment Collation ========= The interface provides read-only accessors, as the character set / collation features are defined outside the Data Dictionary and might not be changed by the Data Dictionary customers. Attributes ---------- - read-only character set of that collation - read-only flag specifying if the collation is compiled - read-only sort_length Schema ====== Attributes ---------- - read-write default collation - read-write created time stamp - read-write last-altered time stamp Operations ---------- - Create a new object in schema: - create a new table - create a new view - create a new system view (system views are used in INFORMATION_SCHEMA and PERFORMANCE_SCHEMA) - create a new stored procedure - create a new stored function - create a new event - Lookup objects in schema by name: - lookup a regular (base) table by name - lookup a view by name - lookup a stored procedure - lookup a stored function - lookup an event - Iterator interface for schema components - Iterator through all tables and views. - Iterator through all tables. - Iterator through all views.
