Define SQL Server Partition Functions

A partition function is the function that specifies how a table or index is partitioned. Use the SQL Server Partition Function Editor to define the properties of the partition boundaries in a SQL Server 2008, 2012, 2014, or 2016 physical model.

To define SQL Server partition functions

  1. Click Target - SQL Server, Partition, Functions on the Model menu.

    The SQL Server Partition Function Editor opens.

  2. Select the partition function in the Navigation Grid that you want to define and work with the following options:

    Note: Click New New icon in property editors to create a new object on the toolbar to create a new partition function. Use the Enter filter text box to filter a very large list of partition functions to quickly locate the one that you want to define.

    Name

    Displays the partition function name. You can change the partition function name in this field.

    Physical Data Type

    Specifies the data type of the column used for the partition. Select a data type from the drop-down list.

    Collation

    Specifies the default collation for the database. Enter the collation value in the column. If collation is not specified, the default collation of SQL Server is assigned.

    Generate

    Generates SQL during forward engineering. Clear the check box if you do not want to generate SQL.

  3. Click the General tab and work with the following options:
    Range Partition Boundary Side

    Specifies if the range partition boundary is from the left or the right. Select one of the options from the drop-down list.

    Boundary Values

    Defines the boundary values for a partition function. The boundary value is a user-defined value for each partition. Click New New icon in property editors to create a new object on the toolbar to define a new boundary value or select one of the existing values and edit it.

  4. (Optional) Click the Comment tab and enter any comments that you want to associate with the object.
  5. (Optional) Click the Where Used tab to view where the object is used within the model.
  6. (Optional) Click the UDPtab to work with user-defined properties for the object.
  7. (Optional) Click the Notestab to view and edit user notes.
  8. (Optional) Click the Extended Notes tab to view or edit user notes.
  9. Click Close.

    The partition function is defined and the SQL Server Partition Function Editor closes.
