alter materialized view partition

The materialized view is partitioned on the partitioning key column or join dependent expressions of the detail table. 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. If you do not want to use PCT refresh, you can just partition by list on GROUPING_ID column. Partition SPLIT/MERGE are supported on materialized views base tables, partition SWITCH isn't supported. Use the ALTER MATERIALIZED VIEW statement to modify an existing materialized view in one or more of the following ways: To change its storage characteristics. Un tablespace ou espace disque logique, est une partition logique de la base contenant un ou plusieurs fichiers. Note that as you increase the number of dimensions and levels, the number of groups to calculate increases dramatically. It includes the typical set of aggregations needed for business intelligence queries. To create a UNION ALL materialized view with two join views, the materialized view logs must have the rowid column and, in the following example, the UNION ALL marker is the columns, 1 marker and 2 marker. To alter its structure so that it is a different type of materialized view. One way to work around this restriction yet still create a materialized view containing the desired VPD-specified subset of rows is to create the materialized view in a user account that has no active VPD policies against the detail relations of the materialized view. At the time of the next automatic refresh, Oracle Database refreshes the materialized view, evaluates the NEXT expression to determine the next automatic refresh time, and continues to refresh automatically. You can use PCT to identify which materialized view rows correspond to a particular partition. To change a materialized view's schema, you must also have CREATE privilege on the new schema. So I believe there is no You are not restricted to using range partitions. This is because VPD would transparently modify the defining query of the materialized view such that the set of rows contained by the materialized view would not match the set of rows indicated by the materialized view definition. A materialized view can't be created on a table with row level security enabled. CQL quick reference. This materialized view benefits from queries that summarize sales numbers by country level or higher to subregion or region level. When I see the recursive SQL, I see only insert /*+ bypass_recursive_check */ and there is no APPEND hint there. SQL> alter system set “_query_on_physical”=false scope=spfile; System altered. 1. You can refresh the materialized view using either ON COMMIT or ON DEMAND refresh. In this example, the desired level of aggregation for the prod_yr_sales_mv is to group by products.prod_category. But after refresh, there is no reduction in the total block numbers as compared to the table. Partition expiration must not be set on materialized views. The owner of the materialized view must have explicitly been granted SELECT access to the referenced tables if the tables are in a different schema. For example, a composite partition using both a time value and a key value could result in a good partition solution for your data. Table 11-2 lists the partition names and their pmarkers for … The top level partition key must consist of only a single column. Please note that partition change tracking is enabled on sales table because of presence of join dependent expression calendar_year in the SELECT list. As an example of using the PMARKER function, consider calculating a typical number, such as revenue generated by a product category during a given year. To support PCT, a materialized view must satisfy the following requirements: At least one of the detail tables referenced by the materialized view must be partitioned. If you attempt to drop, truncate, or exchange a materialized view log partition, … Modify a user-defined type. If joins back to tables or with other materialized views are necessary to retrieve the query result, then the rewritten query can take advantage of partition-wise joins. 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. The column STALENESS will show one of the values FRESH, STALE, UNUSABLE, UNKNOWN, UNDEFINED, or NEEDS_COMPILE to indicate whether the materialized view can be used. If the materialized view is based on a prebuilt table that you never refresh, you will need to drop and re-create the materialized view. Because of the large volume of data held in a data warehouse, partitioning is an extremely useful option when designing a database. The function returns a partition identifier that uniquely identifies the partition for a specified row within a specified partition table. schema_name Is the name of the schema to which the view belongs. third normal form) is that Oracle experiences a high degree of overhead (especially CPU consumption) when joining dozens of tables together, over-and-over again, and partitioning may help. However, any VPD policies against the materialized view itself do not have effect when the materialized view is accessed using query rewrite. What is going on is that, during the day, periodically, the materialized view, and the ones based on it, are set to an INVALID state, as can be seen by inspecting the user_objects view. The following examples illustrate creation of fast refreshable materialized views involving UNION ALL. Like a regular view, the data in a materialized view results from a query. Any DML operation, such as an INSERT, or DELETE, UPDATE, or DDL operation on any dependency in the materialized view will cause it to become invalid. An additional consideration is that you might want to use data compression on your infrequently updated partitions. It is possible and advantageous to track freshness to a finer grain than the entire materialized view. One issue with highly-normalized, non-redundant Oracle table designs (e.g. 2. sales table is partitioned by time_id column and products is partitioned by the prod_id column. When you create a materialized view, there must not be any VPD policies in effect against the base relations of the materialized view for the owner of the materialized view. The ability to identify which rows in a materialized view are affected by a certain detail table partition, is known as Partition Change Tracking. It also illustrates the best approach for creating materialized views using a common scenario. ; The is quite a complicated query involving a few tables, not any view, and is refreshed nightly via a job. Navigational History : Oracle Partition - Range Interval Partitioning; Oracle - Partitions (Table and Indexes) 19 pages. For FAST or FORCE refresh, if COMPLETE or PCT refresh is chosen, this is able to use the TRUNCATE optimizations described earlier. This works fairly well, and I can refresh the most recent partition in 1 - 2 hours (daily). Partitioning separates the view of a table into parts, which often improves query rewrites of partition-wise joins of materialized views with tables or other materialized views. Materialized views with models can use complete refresh or PCT refresh only, and are available for partial text query rewrite only. third normal form) is that Oracle experiences a high degree of overhead (especially CPU consumption) when joining dozens of tables together, over-and-over again, and partitioning may help. Example 9-6 Materialized View Using UNION ALL with Joins and Aggregates. It is possible and advantageous to track freshness to a finer grain than the entire materialized view. If the state of a materialized view is UNUSABLE, you must perform a complete refresh to bring the materialized view back to the FRESH state. Articles Related Prerequisites At least one range partition using the PARTITION clause. If you continue to get a privilege error while trying to create a materialized view and you believe that all the required privileges have been granted, then the problem is most likely due to a privilege not being granted explicitly and trying to inherit the privilege from a role instead. When a materialized view is partitioned on the partitioning key column or join dependent expressions of the detail table, it is more efficient to use a TRUNCATE PARTITION statement to remove one or more partitions of the materialized view during refresh and then repopulate the partition with new data. If there’s some aggregation in the view query, it’s applied only to the batch of freshly inserted data. ALTER KEYSPACE. The shrink clause lets you manually shrink space in a table, index-organized table or its overflow segment, index, partition, subpartition, LOB segment, materialized view, or materialized view log. Oracle Database VLDB and Partitioning Guide, Oracle Database PL/SQL Packages and Types Reference, Chapter 15, "Maintaining the Data Warehouse", "Restrictions on Fast Refresh on Materialized Views with UNION ALL". CQL (Cassandra Query Language) is a query language for the DataStax Enterprise database. Because there's no table inheritance for materialized views, the only way I can think of to do it is to create materialized views manually for each partition (e.g. If you plan to have rolling materialized views in your data warehouse, you should determine how frequently you plan to perform partition maintenance operations, and you should plan to partition fact tables and materialized views to reduce the amount of system administration overhead required when old data is aged out. On DB2: SQL> create materialized view m1 refresh fast on demand as select * from t1@db1; – db1 is database link. The materialized view must contain either the partition key column or a partition marker or ROWID or join dependent expression of the detail table. However, if the staleness of a materialized view is marked as NEEDS_COMPILE, you could issue an ALTER MATERIALIZED VIEW ... COMPILE statement to validate the materialized view and get the correct staleness state. The materialized view sales_per_dt_partition_mv provides the sum of sales for each detail table partition. Cycling keyspace. An expression consisting of columns from tables directly or indirectly joined through equijoins to the partitioned detail table on the partitioning key and which is either a dimensional attribute or a dimension hierarchical parent of the joining key is called a join dependent expression. I therefore create a new version of the materialized view thats FORCE … Data modifications can only occur on the partitioned table. In addition to this, PCT is enabled on products table because of presence of its partitioning key column prod_id in the materialized view. ... on peut changer de fréquence de refresh avec la commande ALTER : SQL> ALTER MATERIALIZED VIEW mv1 refresh complete start with sysdate next sysdate + n. ALTER MATERIALIZED VIEW changes various auxiliary properties of an existing materialized view. Moreover, calendar_month_name is a dimension hierarchical attribute of times.time_id, because calendar_month_name is an attribute of times.mon_id and times.mon_id is a dimension hierarchical parent of times.time_id. ALTER MATERIALIZED VIEW: to change the physical attributes of the materialized view, ... PCTFREE has the same function in the statements that create and alter tables, partitions, clusters, indexes, materialized views, and materialized view logs. You must own the materialized view to use ALTER MATERIALIZED VIEW. You must own the materialized view to use ALTER MATERIALIZED VIEW. The expression calendar_year_name from times_y table is a join dependent expression and the tables times_d, times_m and times_y are join dependent tables. A range partitioning where the database automatically creates partitions for a specified . Assuming the presence of materialized view logs defined earlier, the materialized view can be created using the following DDL: Here, you can correlate a detail table row to its corresponding materialized view row using the join dependent table times and the relationship that times.calendar_month_name is a dimensional attribute determined by times.time_id. Moreover, if you enable query rewrite on a materialized view that references tables outside your schema, you must have the GLOBAL QUERY REWRITE privilege or the QUERY REWRITE object privilege on each table outside your schema. We will now see a Materialized View that contains the Partition Key of the Base Table, which makes it easily possible for the system to associate the rows of the Materialized View with the Partitions. The CREATE MATERIALIZED VIEW syntax does not support that feature. Action: Specify only legal options. The materialized view my_model_mv is on a much smaller data set because it is built on my_groupby_mv and can be maintained by a complete refresh. --- History CREATE TABLE FACT.sales_history ( [date] date NOT NULL, dim1 int NOT NULL, dim2 int NOT NULL, dim3 int NOT … path is an optional case-sensitive path for files in the cloud storage location (i.e. It contains the following topics: Materialized Views in Analytic Processing Environments. Materialized views are an Oracle Silver Bullet when pre-joining tables together for super-fast response time. Oracle does not rewrite against partial stale materialized views if partition change tracking on the changed table is enabled by the presence of join dependent expression in the materialized view. This is because VPD transparently transforms the request query to affect the VPD policy. view_name The name of the new materialized view. Consider a sales data set with two dimensions, each of which has a 4-level hierarchy: Time, which contains (all times), year, quarter, and month. Partitioning a materialized view involves defining the materialized view with the standard Oracle partitioning clauses, as illustrated in the following example. When a materialized view is created, the materialized view depends on the detail tables referenced in its definition. See Chapter 22, "SQL for Modeling" for further details about model calculations. Because there's no table inheritance for materialized views, the only way I can think of to do it is to create materialized views manually for each partition (e.g. path is an optional case-sensitive path for files in the cloud storage location (i.e. The result set eventually becomes stale when data is inserted, updated, and deleted in the base tables. If you use an analytic window function or the MODEL clause, the partition key column or the partition marker or ROWID or join dependent expression must be present in their respective PARTITION BY subclauses. While data warehouse environments typically view data in the form of a star schema, for analytical SQL queries, data is held in the form of a hierarchical cube. Materialized Views and Partitioning are two key Oracle features when working with data warehouses. In addition, you can include a predicate in the WHERE clause of the materialized view that embodies the effect of the VPD policy. You can partition materialized views like you can partition tables. Users who access the materialized view are subject to the VPD policy on the materialized view. ! ALTER MATERIALIZED VIEW. When query rewrite attempts to rewrite a request query that has that VPD policy, it will match up the VPD-generated predicate on the request query with the predicate you directly specify when you create the materialized view. Oracle Database uses this variant of fast refresh (called PCT refresh) with partition truncation if the following conditions are satisfied in addition to other conditions described in "Partition Change Tracking". ALTER TYPE. When creating a materialized view, you can partition selected columns to improve performance. When a data warehouse or data mart contains a time dimension, it is often desirable to archive the oldest information and then reuse the storage for new information. This is because times_y table is joined indirectly through times_m and times_d tables to sales table on its partitioning key column time_id. PCT is not supported for a materialized view that refers to views, remote tables, or outer joins. Search Term. The following example shows a UNION ALL of a materialized view with joins and a materialized view with aggregates. If query rewrite were to perform a text match transformation against a request query with a VPD policy, the effect would be to negate the VPD policy. Materialized views with multiple aggregate groups will give their best performance for refresh and query rewrite when partitioned appropriately. When one or more of the detail tables are partitioned, it may be possible to identify the specific rows in the materialized view that correspond to a modified detail partition(s); those rows become stale when a partition is modified while all other rows remain fresh. When creating a view or materialized view, the owner needs to have the necessary permissions to access the underlying base relations of the view or materialized view that they are creating. Scripting on this page enhances content navigation, but does not change the content in any way. In particular, materialized views created with the ROLLUP clause are likely candidates. To alter a materialized view in a keyspace other than the current keyspace, put the keyspace name in front of the name of the materialized view, followed by a period. Let's consider another example: Here, times table is denormalized into times_d, times_m and times_y tables. The word "snapshot" is synonymous with "materialized view". It allows you to store your data in many filegroups and keep the database files in different disk drives, with the ability to move … For instance, if a detail table partition is truncated or dropped, the affected rows in the materialized view are identified and deleted. Thanks Pavan dbmullen. This lets users create materialized views containing aggregates on some level higher than the partitioning key of the detail table. In 11g, alter materialized view drop partition is possible, having the same effect but looking nicer :-) Be aware that after the drop partition command, the MV will not be used for query rewrite unless you say alter materialized view consider fresh and having QUERY_REWRITE_INTEGRITY=TRUSTED set. Unlike the general case of a PL/SQL function in a materialized view, use of the DBMS_MVIEW.PMARKER does not prevent rewrite with that materialized view even when the rewrite mode is QUERY_REWRITE_INTEGRITY = ENFORCED. select_statement The SELECT list in the materialized view definition needs to meet at least one of these two criteria: 1. When a materialized view is partitioned on the partitioning key column or join dependent expressions of the detail table, it is more efficient to use a TRUNCATE PARTITION statement to remove one or more partitions of the materialized view during refresh and then repopulate the partition with new data. A couple of things can be noted in this example. In 10g, this is the only way to do it. For all security concerns, a materialized view serves as a view that happens to be materialized when you are directly querying the materialized view. Partitioning the fact tables also improves the opportunity of fast refreshing the materialized view because this may enable Partition Change Tracking (PCT) refresh on the materialized view. for previous years. Database dismounted. The partitioning key can only be a single . If there were 1000 different products sold each month, it would result in 12,000 rows in the materialized view. The addition of Partition Change Tracking (PCT) features in Oracle 10g significantly expands the ability to keep materialized views synchronized with the sources of their data, and Partition Maintenance Operations (PMOPs) offer even faster refreshes of materialized views when a materialized view is partitioned in the same fashion as its source table. When the database rewrites a query to run against materialized views, the query can take advantage of the same performance features from which queries running against tables directly benefit. If the materialized view is being created with ON COMMIT REFRESH specified, then the owner of the materialized view requires an additional privilege if any of the tables in the defining query are outside the owner's schema. The state is maintained automatically. Table options are defined when the materialized view is created. First, ask yourself WHY you wish to make your index disabled? Changes materialized view table properties. Consider the following: In this query, times table is a join dependent table since it is joined to sales table on the partitioning key column time_id. Consider an example of a materialized view storing the yearly sales revenue for each product category. Thus, the presence of the index or materialized view presents no additional security checking. "GSP_RELATEDEVENTS1" NOLOGGING REFRESH FORCE --START WITH SYSDATE NEXT SYSDATE + 3/1440 AS SELECT DISTINCT ser_id AS R_SER_ID, WM_CONCAT (REL_NAME) AS R_NAME FROM sd_servicecalls, cdm_serv_evt_relations, GSP_EVENTS WHERE sre_from = ser_oid AND sre_to = EVENT_TO_OID GROUP BY ser_id; ALTER MATERIALIZED VIEW "OVSD". In addition, when you create or refresh a materialized view, the owner of the materialized view must not have any active VPD policies in effect against the base relations of the materialized view, or an error is returned. Try searching other guides. To enable or disable query rewrite Maintaining materialized views A subsequent INSERT statement adds a new row to the sales_part3 partition of table sales. Changes password, and set superuser or login options. ORACLE instance shut down. Partition pruning: only relevant aggregate groups will be accessed, thereby greatly reducing the query processing cost. Scripting on this page enhances content navigation, but does not change the content in any way. Note that Greenplum Database distribution key columns cannot be renamed. Using them together though can sometimes cause unexpected problems when you need to refresh them, as we found on a recent project. You can issue SELECT statements to query a materialized view, in the same way that you can query other tables or views in the database. This section discusses the concepts used by analytic SQL and how relational databases can handle these types of queries. Hence, the most effective partitioning scheme for these materialized views is to use composite partitioning (range-list on (time, GROUPING_ID) columns). Product, which contains (all products), division, brand, and item. See Oracle Database SQL Language Reference for data compression syntax and restrictions and "Storage And Table Compression" for details regarding compression. USE. This enables partition change tracking on products table with significantly less cardinality impact than grouping by the partition key column prod_id. Handling the explosion of groups has historically been the major challenge in data storage for online analytical processing systems. CREATE MATERIALIZED VIEW complete_calls TABLESPACE live_cdrtbs BUILD IMMEDIATE REFRESH COMPLETE START WITH SYSDATE NEXT SYSDATE + 2/24 AS ( select distinct(ic.callid) callid , ic.CG , ic.CD , ic.RE, ic.OPC, … This would generally be significantly less than the cardinality impact of including the partition key columns.
