Manage Partition Wizard F1 Help

 

Applies To: SQL Server 2016

Use the Manage Partition Wizard to manage and modify existing partitioned tables through partition switching or the implementation of a sliding window scenario. This wizard can ease the management of your partitions and simplify the regular migration of data in and out of your tables.

To start the Manage Partition Wizard

  • In SQL Server Management Studio, select the database, right-click the table on which you want to create partitions, point to Storage, and then click Manage Partition.

    Note If Manage Partition is unavailable, you may have selected a table that does not contain partitions. Click Create Partition on the Storage submenu and use the Create Partition Wizard to create partitions in your table.

For general information about partitions and indexes, see Partitioned Tables and Indexes.

This section provides the information that is required to manage, modify, and implement partitions using the Manage Partition Wizard.

The following sections provide help on the pages of the Manage Partition Wizard.

Create a Staging Table

Partition switching is a common partitioning task if you have a partitioned table that you migrate data into and out of on a regular basis; for example, you have a partitioned table that stores current quarterly data, and you must move in new data and archive older data at the end of each quarter.

The wizard designs the staging table with the same partitioning column, table and column structure, and indexes, and stores the new table in the filegroup where your source partition is located.

To create a staging table to switch in or switch out partition data, select Create a staging table for partition switching.

Sliding Window Scenario

To manage your partitions in a sliding-window scenario, select Manage partitioned data in a sliding window scenario.

Create a staging table for partition switching
Creates a staging table for the data you are switching in or switching out of the existing partitioned table.

Switch out partition
Provides options when removing a partition from the table.

Switch in partition
Provides options when adding a partition to the table.

Manage partitioned data in a sliding window scenario
Appends an empty partition to the existing table that can be used for switching in data. The wizard currently supports switching into the last partition and switching out the first partition.

Use the Select Partition Switching-In options page to select the staging table you are switching into the partitioned table.

Show All Partitions
Select to show all partitions, including the partitions currently in the partitioned table.

Partition grid
Displays the partition name, Left boundary, Right boundary, Filegroup, and Row count of the partitions you selected.

Switch in table
Select the staging table that contains the partition that you want to add to your partitioned table. You must create this staging table before you switch-in partitions with the Manage PartitionsWizard.

Use the Select Partition Switching-Out options page to select the partition and the staging table to hold the partitioned data that you are switching out of the partitioned table.

Partition grid
Displays the partition name, Left boundary, Right boundary, Filegroup, and Row count of the partitions you selected.

Switch out table
Choose a new table or an existing table to switch-out your data to.

New
Enter a new name for the staging table you want to use for the partition to switch out of the current source table.

Existing
Select an existing staging table you want to use for the partition you want to switch out of the current source table. If the existing table contains data, this data will be overwritten with the data you are switching out.

Use the Select the Staging Table Options page to create the staging table you want to use for switching your partitioned data.

Staging tables must reside in the same filegroup of the selected partition where the source table is located. The staging table must mirror the design of both the source table and the destination table.

You can also create the same indexes in the staging table that exist in the source partition. The staging table automatically contains a constraint based on the elements of the source partition. This constraint is typically generated from the boundary value of the source partition.

Staging table name
Create a name for the staging table or accept the default name displayed in the edit box.

Switch partition
Select the source partition that you want to switch out of the current table.

New boundary value
Select or enter the boundary value you want for the partition in the staging table.

Filegroup
Select a filegroup for the new table.

Create Script

When the wizard finishes, it creates a script in Query Editor to modify partitions in the table. Select Create Script if you want to review the script, and then execute the script manually.

Script to file
Generate the script to a .sql file. Specify either Unicode or ANSI text. To specify a name and location for the file, click Browse.

Script to Clipboard
Save the script to the Clipboard.

Script to New Query Window
Generate the script to a Query Editor window. If no editor window is open, a new editor window opens as the target for the script.
