Specify COMPLETE for the complete refresh method, which is implemented by executing the defining query of the materialized view. Moving a materialized view to a managed access schema (using the ALTER MATERIALIZED VIEW … RENAME TO syntax) is prohibited unless the materialized view owner (i.e. Only the renaming of base table columns is supported. Description. If you specify ON COMMIT or ON DEMAND, you cannot also specify START WITH or NEXT. ALTER MATERIALIZED VIEW changes various auxiliary properties of an existing materialized view.. You must own the materialized view to use ALTER MATERIALIZED VIEW.To change a materialized view's schema, you must also have CREATE privilege on the new schema. This clause is not valid if your database is in automatic undo mode, because in that mode Oracle Database uses undo tablespaces instead of rollback segments. When you change the refresh method to FAST in an ALTER MATERIALIZED VIEW statement, Oracle Database does not perform this verification. Examples. this form The keywords and parameters of the components of the alter_iot_clauses have the same semantics as in ALTER TABLE, with the restrictions that follow. Specify or change the logging characteristics of the materialized view. Synopsis ALTER MATERIALIZED VIEW [ IF EXISTS ] name action [, ... ] ALTER MATERIALIZED VIEW name DEPENDS ON EXTENSION extension_name ALTER MATERIALIZED VIEW [ IF EXISTS ] name RENAME [ COLUMN ] column_name TO new_column_name ALTER MATERIALIZED VIEW [ IF EXISTS ] name RENAME TO new_name ALTER MATERIALIZED VIEW … Please refer to the logging_clause for a full description of this clause.

If any of the master tables are in another schema, you must have the GLOBAL QUERY REWRITE privilege. At the time of the next automatic refresh, Oracle Database refreshes the materialized view, evaluates the NEXT expression SYSDATE+7 to determine the next automatic refresh time, and continues to refresh the materialized view automatically once a week. ALTER MATERIALIZED VIEW name DEPENDS ON EXTENSION extension_name ALTER MATERIALIZED VIEW [ IF EXISTS ] name RENAME [ COLUMN ] column_name TO new_column_name ALTER MATERIALIZED VIEW [ IF EXISTS ] name RENAME TO new_name ALTER MATERIALIZED VIEW [ IF EXISTS ] name SET SCHEMA new_schema ALTER MATERIALIZED VIEW … Other clauses supported by SQL Anywhere, including ALTER CONSTRAINT, RENAME, PCTFREE, ENCRYPTED, and DISABLE MATERIALIZED VIEW, are vendor extensions. Conversely, SQL Anywhere supports modifying a column's data type through the ALTER clause directly. If you specify a START WITH value but omit the NEXT value, Oracle Database refreshes the materialized view only once. Rowid Materialized View Log: Example The following statement alters an existing primary key materialized view log to also record rowid information:. If you alter a table that is a master table for one or more materialized views, then Oracle Database marks the materialized views INVALID. the role that has the OWNERSHIP privilege on the materialized view) also owns the target schema. Oracle Database invalidates all objects that depend on the renamed object, such as views, synonyms, and stored procedures and functions that refer to a renamed table. A materialized view is stale if changes have been made to the contents of any of its master tables. If the materialized view fails to revalidate, it cannot be refreshed or used for query rewrite. Please refer to ALTER TABLE for information on the PCTFREE, PCTUSED, and INITRANS parameters and to storage_clause for information about storage characteristics. Commented: 2009-08-05. it-rex: I was thinking about your question. Copyright © 1996-2020 The PostgreSQL Global Development Group, PostgreSQL 13.1, 12.5, 11.10, 10.15, 9.6.20, & 9.5.24 Released. ALTER MATERIALIZED VIEW . Specify WITH PRIMARY KEY to change a rowid materialized view to a primary key materialized view. A materialized view is a database object that contains the results of a query. This clause has the same semantics in CREATE MATERIALIZED VIEW and ALTER MATERIALIZED VIEW statements. However, a disabled materialized view can be refreshed. Please refer to "CACHE | NOCACHE | CACHE READS" in the documentation on CREATE TABLE for more information about this clause. Cleanup drop materialized view mv ; drop materialized view log on t2 ; < You must own the materialized view to use ALTER MATERIALIZED VIEW. Use the alter_mv_refresh clause to change the default method and mode and the default times for automatic refreshes. If you specify a complete refresh, Oracle Database performs a complete refresh even if a fast refresh is possible. CONSTRAINTS Clause" in the documentation on CREATE MATERIALIZED VIEW. LOB storage behaves for materialized views exactly as it does for tables. Please refer to the table_compression clause of CREATE TABLE for more information on table compression. For example, you cannot include CURRENT_TIME or USER. CONSIDER FRESH directs Oracle Database to consider the materialized view fresh and therefore eligible for query rewrite in the TRUSTED or STALE_TOLERATED modes. ALTER MATERIALIZED VIEW. For a table that has a materialized view, cannot drop a column from the table even if the column is not used in the materialized view. RENAME TO new_name. This statement allows sales_by_month_by_state to be eligible for query rewrite in TRUSTED mode even after you have performed partition maintenance operations on the master tables of sales_by_month_by_state: Complete Refresh: Example The following statement specifies a new refresh method, a new NEXT refresh time, and a new interval between automatic refreshes of the emp_data materialized view (created in "Periodic Refresh of Materialized Views: Example"): The START WITH value establishes the next automatic refresh for the materialized view to be 9:00 a.m. tomorrow. Collectively these source objects are called master tables (a replication term) or detail tables (a data warehousing term). Changes the table properties of a materialized view. How to rename them? Specify the name of the materialized view to be altered. The system does not allow an insert, update, or delete on a view. Action: Do… Renaming columns in views, materialized query tables (MQTs), declared and created temporary tables, and other table-like objects is not supported. To enable a materialized view for query rewrite: If all of the master tables in the materialized view are in your schema, you must have the QUERY REWRITE privilege. This clause is supported for backward compatibility with replication environments containing older versions of Oracle Database that still use rollback segments. For complete information on this clause, please refer to CREATE MATERIALIZED VIEW ... "USING ROLLBACK SEGMENT Clause". The changes are stored either in the materialized view log associated with the master table (for conventional DML changes) or in the direct loader log (for direct-path INSERT operations). If the contents of the master tables of a materialized view are modified, the data in the materialized view must be updated to make the materialized view accurately reflect the data currently in its master table(s). The modify_LOB_storage_clause lets you modify the physical attributes of the LOB attribute lob_item or the LOB object attribute. Specifies the identifier for the view to alter. The NOCOMPRESS keyword disables table compression. To change a materialized view's schema, you must also have CREATE privilege on the new schema. ALTER MATERIALIZED VIEW changes various auxiliary properties of an existing materialized view.. You must own the materialized view to use ALTER MATERIALIZED VIEW.To change a materialized view's schema, you must also have CREATE privilege on the new schema. Use the alter_iot_clauses to change the characteristics of an index-organized materialized view. Use the RENAME statement to rename a table, view, sequence, or private synonym.. Oracle Database automatically transfers integrity constraints, indexes, and grants on the old object to the new object. The Oracle manual page for ALTER MATERIALIZED VIEW however does not indicate that constraints can be added this way. The parallel_clause lets you change the default degree of parallelism for the materialized view. Materialized View Add Columns Hi Tom,I have added a new column in my master table and i want this column to be reflected in my Materialized view is this possible without Re creating iti have to fetch all columns from my master table in my view.please suggest. The staleness state is displayed in the STALENESS column of the ALL_MVIEWS, DBA_MVIEWS, and USER_MVIEWS data dictionary views. Therefore, actual updates to those tables pending refresh are purged with respect to the materialized view. Specify ENABLE to enable the materialized view for query rewrite. In addition, the owner of the materialized view must have SELECT access to any master tables that the materialized view owner does not own. Specify FAST for the incremental refresh method, which performs the refresh according to the changes that have occurred to the master tables. To alter the owner, you must also be a direct or indirect member of the new owning role, and that role must have CREATE privilege on the materialized view's schema. Once a materialized view has been created, the optimizer will be able to exploit its definition semantics to automatically rewrite incoming queries using materialized views, and hence, accelerate query execution. Specify START WITH date to indicate a date for the first automatic refresh time. The name of the extension that the materialized view is to depend on. Specify new values for the PCTFREE, PCTUSED, and INITRANS parameters (or, when used in the USING INDEX clause, for the INITRANS parameter only) and the storage characteristics for the materialized view. >> ORA-32318: cannot rename a materialized view mrjoltcola. ALTER MATERIALIZED VIEW changes various auxiliary properties of an existing materialized view. Restrictions on Enabling Materialized Views Enabling materialized views is subject to the following restrictions: If the materialized view is in an invalid or unusable state, it is not eligible for query rewrite in spite of the ENABLE mode. For complete information on this clause, please refer to shrink_clause in the documentation on CREATE TABLE. The new schema for the materialized view. If the materialized view is not eligible for fast refresh, Oracle Database returns an error when you attempt to refresh this view. NOCACHE specifies that the blocks are placed at the least recently used end of the LRU list. Identifiers enclosed in double quotes are also case-sensitive. Please refer to alter_table_partitioning in the documentation for ALTER TABLE. please use Changes password, and set superuser or login options. your experience with the particular feature or requires further clarification, MODIFY PARTITION UNUSABLE LOCAL INDEXES Use this clause to mark UNUSABLE all the local index partitions associated with partition. When an object (table, column, etc.) If an object upon which the materialized view depends is dropped or altered, the materialized view remains accessible, but it is invalid for query rewrite. CONSIDER FRESH: Example The following statement instructs Oracle Database that materialized view sales_by_month_by_state should be considered fresh. Restriction on ON COMMIT This clause is supported only for materialized join views and single-table materialized aggregate views. This clause lets you schedule the times and specify the method and mode for Oracle Database to refresh the materialized view. Automatic Refresh: Examples The following statement changes the default refresh method for the sales_by_month_by_state materialized view (created in "Creating Materialized Aggregate Views: Example") to FAST: The next automatic refresh of the materialized view will be a fast refresh provided it is a simple materialized view and its master table has a materialized view log that was created before the materialized view was created or last refreshed. See the descriptions for ALTER TABLE for details. ALTER MATERIALIZED VIEW LOG ON order_items ADD ROWID; Materialized View Log EXCLUDING NEW VALUES: Example The following statement alters the materialized view log on hr.employees by adding a filter column and excluding … The FROM clause of the query can name tables, views, and other materialized views. The syntax and general functioning of the partitioning clauses for materialized views is the same as for partitioned tables. I have a materialized view with an unknown column name, and I need to give that column a name. Oracle Database Advanced Replication for restrictions on fast refresh in replication environments, Oracle Data Warehousing Guide for restrictions on fast refresh in data warehouse environments. This example requires that you have already defined a materialized view log with a primary key on order_data. ALTER MATERIALIZED VIEW name DEPENDS ON EXTENSION extension_name ALTER MATERIALIZED VIEW [ IF EXISTS ] name RENAME [ COLUMN ] column_name TO new_column_name ALTER MATERIALIZED VIEW [ IF EXISTS ] name RENAME TO new_name ALTER MATERIALIZED VIEW … This reference uses the term master tables for consistency. ALTER TABLE. Synopsis ALTER MATERIALIZED VIEW [ IF EXISTS ] name action [, ... . ] (These restrictions enforce that altering the owner doesn't do anything you couldn't do by dropping and recreating the materialized view. If you omit both ON COMMIT and ON DEMAND, ON DEMAND is the default. Restrictions on Altering Index-Organized Materialized Views You cannot specify the mapping_table_clause or the key_compression clause of the index_org_table_clause. Restrictions on FAST Refresh FAST refresh is subject to the following restrictions: When you specify FAST refresh at create time, Oracle Database verifies that the materialized view you are creating is eligible for fast refresh. To create a view with an external table, include the WITH NO SCHEMA BINDING clause. Collectively these source objects are called master tables (a replication term) or detail tables (a data warehousing term). Because Oracle Database cannot guarantee the freshness of the materialized view, query rewrite in ENFORCED mode is not supported. If you omit schema, Oracle Database assumes the materialized view is in your own schema. NAME ALTER_MATERIALIZED_VIEW - change the definition of a materialized view SYNOPSIS. However, a superuser can alter ownership of any view anyway.). Primary key materialized views allow materialized view master tables to be reorganized without affecting the ability of the materialized view to continue to fast refresh. If you omit the START WITH value, Oracle Database determines the first automatic refresh time by evaluating the NEXT expression with respect to the creation time of the materialized view. Specify NEXT to indicate a date expression for calculating the interval between automatic refreshes. ALTER VIEW changes various auxiliary properties of a view. ALTER MATERIALIZED VIEW — change the definition of a materialized view. Restrictions on Rescoping REF Columns You can rescope only one REF column or attribute in each ALTER MATERIALIZED VIEW statement, and this must be the only clause in this statement. Only the renaming of base table columns is supported. PostgreSQL v12.5: PostgreSQL is a powerful, open source object-relational database system that uses and extends the SQL language combined with many features that safely store and scale the most complicated data workloads. Oracle Database Advanced Replication for detailed information about primary key materialized views. The DEPENDS ON EXTENSION form marks the materialized view as dependent on an extension, such that the materialized view will automatically be dropped if the extension is dropped. Invalid materialized views cannot be used by query rewrite and cannot be refreshed. The LOB_storage_clause lets you specify the storage characteristics of a new LOB. Description. Views are read-only. I can't just recreate the view because it took a long time to create. is renamed, other objects that reference it must be updated with the new name. You can enable query rewrite only if expressions in the statement are repeatable. The name (optionally schema-qualified) of an existing materialized view. Renaming columns in views, materialized query tables (MQTs), declared and created temporary tables, and other table-like objects is not supported. You can enable query rewrite only if all user-defined functions in the materialized view are DETERMINISTIC. Specify FORCE if, when a refresh occurs, you want Oracle Database to perform a fast refresh if one is possible or a complete refresh otherwise. Description. The databases containing the master tables are called the master databases. Please refer to the allocate_extent_clause for a full description of this clause. The FROM clause of the query can name tables, views, and other materialized views. Specify ON COMMIT if you want a fast refresh to occur whenever Oracle Database commits a transaction that operates on a master table of the materialized view. Until the documentation says this is legal it is best to use ALTER TABLE.

To change a materialized view's schema, you must also have CREATE privilege on the new schema. You must own the view to use ALTER VIEW.To change a view's schema, you must also have CREATE privilege on the new schema. This clause also sets the staleness state of the materialized view to UNKNOWN. Use the alter_mv_refresh clause to change the default method and mode and the default times for automatic refreshes. Please refer to the LOB_storage_clause (in CREATE TABLE) for information on the LOB storage parameters. ALTER MATERIALIZED VIEW changes various auxiliary properties of an existing materialized view..

ALTER MATERIALIZED VIEW [ IF EXISTS ] name action [, ... . ] Oracle strongly recommends that you use automatic undo mode. At that point, Oracle Database performs a complete refresh of the materialized view, evaluates the NEXT expression, and subsequently refreshes the materialized view every week. Specifies the new identifier for the view… ALTER ROLE. The following statement establishes a new interval between automatic refreshes for the sales_by_month_by_state materialized view: Because the REFRESH clause does not specify a START WITH value, the next automatic refresh occurs at the time established by the START WITH and NEXT values specified when the sales_by_month_by_state materialized view was created or last altered. Modification of LOB storage behaves for materialized views exactly as it does for tables. ... You cannot rename a static column, since you cannot use a static column in the table's primary key. ALTER MATERIALIZED VIEW changes various auxiliary properties of an existing materialized view.. You must own the materialized view to use ALTER MATERIALIZED VIEW.To change a materialized view's schema, you must also have CREATE privilege on the new schema. Use the MODIFY scoped_table_ref_constraint clause to rescope a REF column or attribute to a new table or to an alias for a new column. Specify the schema containing the materialized view. Materialized views are not eligible for fast refresh if the defining query contains an analytic function. Today, I have something on materialized views. This reference uses the term master tables for consistency. Renames the specified column to a new name that is not currently used for any other columns in the table. Last week, I had this requirement to rename a materialized view and initial search on how to the same landed me on to ORA-32318. Oracle Data Warehousing Guide for more information on query rewrite and the implications of performing partition maintenance operations on master tables. If the contents of the master tables of a materialized view are modified, then the data in the materialized view must be updated to make the materialized view accurately reflect the data currently in its master table(s). If you see anything in the documentation that is not correct, does not match For you to specify this clause, the master table must contain an enabled primary key constraint and must have defined on it a materialized view log that logs primary key information. A materialized view is a database object that contains the results of a query. Do not add a column with the same name as an existing column but with a different data type. If the identifier contains spaces or special characters, the entire string must be enclosed in double quotes. Specify COMPILE to explicitly revalidate a materialized view. ALTER MATERIALIZED VIEW changes various auxiliary properties of an existing materialized view.. You must own the materialized view to use ALTER MATERIALIZED VIEW.To change a materialized view's schema, you must also have CREATE privilege on the new schema.

For information on revalidating a materialized view, see ALTER MATERIALIZED VIEW. Use this clause to determine whether the materialized view is eligible to be used for query rewrite. For data that will be accessed frequently, CACHE specifies that the blocks retrieved for this table are placed at the most recently used end of the LRU list in the buffer cache when a full table scan is performed. For complete information on this clause, please refer to parallel_clause in the documentation on CREATE TABLE. The privileges required to alter a materialized view should be granted directly, as follows: The materialized view must be in your own schema, or you must have the ALTER ANY MATERIALIZED VIEW system privilege.
