You can create subpartitions in a composite partitioned table using a subpartition template. A subpartition template simplifies the specification of subpartitions by not requiring that a subpartition descriptor be specified for every partition in the table. Instead, you describe subpartitions only once in a template, then apply that subpartition template to every partition in the table. For interval-* composite partitioned tables, the subpartition template is the only way to define subpartitions for interval partitions. The subpartition template is used whenever a subpartition descriptor is not specified for a partition. If a subpartition descriptor is specified, then it is used instead of the subpartition template for that partition. If no subpartition template is specified, and no subpartition descriptor is supplied for a partition, then a single default subpartition is created. Specifying a Subpartition Template for a *-Hash Partitioned Table In the case of [range | interval | list]-hash partitioned tables, the subpartition template can describe the subpartitions in detail, or it can specify just the number of hash subpartitions. The following example creates a range-hash partitioned table using a subpartition template: CREATE TABLE emp_sub_template (deptno NUMBER, empname VARCHAR(32), grade NUMBER) PARTITION BY RANGE(deptno) SUBPARTITION BY HASH(empname) SUBPARTITION TEMPLATE (SUBPARTITION a TABLESPACE ts1, SUBPARTITION b TABLESPACE ts2, SUBPARTITION c TABLESPACE ts3, SUBPARTITION d TABLESPACE ts4 ) (PARTITION p1 VALUES LESS THAN (1000), PARTITION p2 VALUES LESS THAN (2000), PARTITION p3 VALUES LESS THAN (MAXVALUE) ); This example produces the following table description: Every partition has four subpartitions as described in the subpartition template. Each subpartition has a tablespace specified. It is required that if a tablespace is specified for one subpartition in a subpartition template, then one must be specified for all. The names of the subpartitions, unless you use interval-* subpartitioning, are generated by concatenating the partition name with the subpartition name in the form:

Based on boundary_value, the Database Engine splits one of the existing ranges into two. Of these two, the one where the new boundary_value resides is considered the new partition. Before that We should add on empty file for this database and add it to Partition scheme using NEXT USED.

Do you have tables and indexes that have grown really large? Are you moving around a lot more data than you used to? Are your windows for jobs and maintenance getting tighter? If you answered yes to any of these questions, partitioning may be for you! With partitioning, you can break a table or index down into smaller more manageable chunks. It can help you perform maintenance on just part of a table or index. You can even move data in and out of tables with quick and easy metadata only operations. We’ll go over basic partitioning concepts such as horizontal vs. vertical partitioning, and techniques like partitioned views and full blown table partitioning. We’ll look at how partitioning affects things under the hood. Finally you'll see some cool demos/tricks around index maintenance and data movement. At the end of this session you’ll have a firm understanding of how partitioning works and know how to make decisions on how and when to implement. You'll learn… • The components of table partitioning and how they fit together • How to make your index maintenance partition aware • How Partition elimination can help your queries • How to split different parts of tables over different storage tiers • How to manage partitions. We'll demo this by implementing the sliding window technique. Brandon Leach is a senior DBA with SurveyMonkey in Palo Alto, CA.

Split partition is very convenient if you need more partitions to store various kinds of data, such as family photos, software applications or personal business files etc. With the help of this function, you can split one big partition into two or more smaller ones.

Click here to Subscribe to IT PORT Channel : https://www.youtube.com/channel/UCMjmoppveJ3mwspLKXYbVlg Partitioning is the process of dividing a single large table/index into multiple logical chunks/partitions in such way that each partition can be managed separately without having much overall impact on the availability of the table/index. Partitioning improves the manageability and availability of table/index as well as the performance of the queries running against this partitioned table/index SQL Server supports table and index partitioning. The data of partitioned tables and indexes is divided into units that can be spread across more than one filegroup in a database. The data is partitioned horizontally, so that groups of rows are mapped into individual partitions. All partitions of a single index or table must reside in the same database. The table or index is treated as a single logical entity when queries or updates are performed on the data.

Click here to Subscribe to IT PORT Channel : https://www.youtube.com/channel/UCMjmoppveJ3mwspLKXYbVlg Horizontal partitioning divides a large table into smaller more manageable parts without having to create separate tables for each part. Data in a partitioned table is physically stored in groups of rows called partitions and each partition can be accessed and maintained separately. Partitioning is not visible to end users, a partitioned table behaves like one logical table when queried Partitioned Column : Data in a partitioned table is partitioned based on a single column, the partition column, often called the partition key. Only one column can be used as the partition column, but it is possible to use a computed column Partition Function: It defines how to partition data based on the partition column. The partition function does not explicitly define the partitions and which rows are placed in each partition Partition Scheme : It maps the logical partitions to physical file groups. It is possible to map each partition to its own file group or all partitions to one file group

SDU Tools are free tools for SQL Server developers and DBAs. This tool helps to split a delimited string in T-SQL. It can have any delimiter (comma for CSV, tab for TSV, etc.) Instead of one row per value, it returns one column per value and has an option to trim the strings as well. You'll find more info about SDU Tools and download details at http://www.sqldownunder.com/Resources/SDUTools

Click here to Subscribe to IT PORT Channel : https://www.youtube.com/channel/UCMjmoppveJ3mwspLKXYbVlg Vertical partitioning divides a table into multiple tables that contain fewer columns. The two types of vertical partitioning are normalization and row splitting a) NORMALIZATION is the standard database process of removing redundant columns from a table and putting them in secondary tables that are linked to the primary table by primary key and foreign key relationships. b) ROW SPLITTING divides the original table vertically into tables with fewer columns. Each logical row in a split table matches the same logical row in the other tables as identified by a UNIQUE KEY column that is identical in all of the partitioned tables. Explained in Tamil
