Sorting Data in Views

Common Sort Functionality

Some sort functionality is common to graphs, pivot tables, tables, and trellises, although you cannot sort values interactively on a graph.

Graphs, pivot tables, tables, and trellises reflect the sorting that you specify in the Selected Columns pane of the Criteria tab for attribute columns and hierarchical columns. Use the Sorting menu options that are available from the Options button for a column. These sorting options provide the ability to sort by a single column or by multiple columns, each in either ascending or descending order. By creating sorts for multiple columns, you can specify multiple level sorts such as second-level and third-level sorts of the data. These sort levels are indicated with numbers and a sort icon for the column in the Criteria tab.

The options that you specify on the Criteria tab serve as the initial sorting state of the analysis. You can modify the sort later when the analysis is used in a table, pivot table, or trellis.

When you sort items in a hierarchical column, you always sort within the parent. That is, children are never sorted outside of their parent. The children are displayed below the parent in the proper sort order; the parent is not sorted within its children.

If you include totals in a view, then those values are not sorted. They remain in the location in which you placed them, regardless of sorting.

If you sort an attribute column or hierarchical column that includes a group, then that group is always displayed at the bottom of the list. If there are multiple groups, then the groups are listed in the order in which their corresponding steps are specified in the Selection Steps pane.

Sorting Data

Sorting allows you to quickly sort rows and columns of a view, either from lowest to highest data values, or from highest to lowest. You can also return the order to the order in the data source by clearing all sorts. You can specify alphanumeric sorts on the row and column edges of pivot table views, table views, and trellis views.

You make sorting specifications in various ways, including those in the following list:

• In the Selected Columns pane of the Criteria tab, click the Options button beside the column and select the appropriate sort option from the menu. For more information on the sorting options menu, see "Sorting Options Menu".

• Right-click in a pivot table, table, or trellis, select Sort or Sort Column (whichever is available), and then select the appropriate sorting option from the menu. For more information on the sorting options menu, see "Sorting Options Menu".

• Hover the mouse pointer over the area to the right of the column name in the header of a pivot table, table, or trellis and click either the upward-facing triangle (Sort Ascending) or the downward-facing triangle (Sort Descending) for that column. These sort specifications override those that you make with the right-click menu.

  If you see a shaded-in sort button in the column header or the row header, then you know that the column contains a primary sort. You can add a second-level or third-level sort by hovering over another innermost column header or row header and clicking the appropriate sort button or clicking the right-mouse button.

Any sorting options that you specify in a view override those that were made in the Selected Columns pane.

Clearing Sorts

You can use various methods to clear sorts:

• For sorts that have been applied in the Selected Columns pane, click Clear All Sorts in All Columns. The sort specifications that you made in the Selected Columns pane are removed. Sorts that you specified in a view remain.

• For sorts that have been applied directly in a pivot table, table, or trellis:

  • Click a sort button in an unsorted column to remove the primary sort from the column to which it now applies and apply it to the column whose button you just clicked.

  • Select the Clear All Sorts in View option from the right-mouse menu.

Example 1: Sorting with a Single Column on Each Edge

Suppose that you have a pivot table with Time Hierarchy on the column edge and Offices Hierarchy on the row edge; both are hierarchical columns. 1 - Revenue in dollars is the measure that is shown in the pivot table. You can sort the Offices Hierarchy by the 1 - Revenue for a particular year as highest revenue to lowest revenue, or lowest to highest, or no sorting at all.

Figure 3-23 shows an example of sorting Offices Hierarchy by 1 - Revenue for year 2008, in ascending order. The Corporate Total parent is always displayed above its children. The values for other years might not be sorted numerically, because only year 2008 was selected.

Figure 3-23 Sorting Example: Offices Hierarchy for Year 2008

Figure 3-24 shows an example of sorting the Time Hierarchy by the 1 - Revenue for Corporate Total. The years are re-arranged in the order 2009 and 2008. In 2009, Corporate Total had its lowest value; and in 2008, it had its highest value.

Example 2: Sorting with Two Columns on the Row Edge

Suppose that you have a pivot table with the Time Hierarchy on the column edge and P1 Products and the Offices Hierarchy on the row edge, with Products outside Offices. 1 - Revenue in dollars is the measure that is shown in the pivot table. You can sort the row edge by the 1 - Revenue for 2008 in descending order. The Offices are sorted as in Example 1, but the Products are not sorted, because they are in the outermost layer. See Figure 3-25.

Example 3: Sorting with Two Measures on the Column Edge

Suppose that you have a pivot table with the Time Hierarchy on the column edge and the Offices Hierarchy on the row edge. Both 1 - Revenue and 2 - Billed Quantity are the measures in the pivot table as shown in Figure 3-26. If you try to sort the years by the leaf-node for GenMind Corp using the upward facing triangle (Sort Ascending), then the first measure on the column edge (reading left to right) is chosen as the one on which to sort. If 1 - Revenue is the first measure on the edge, then the pivot table is sorted as shown in Figure 3-27.

Figure 3-26 Sorting Example: Sorting with Two Measure on the Column Edge - Before Sorting

Figure 3-27 Sorting Example: Sorting with Two Measures on Column Edge - After Sorting

If the measures are on the row edge and you sort by a year, then the top-most measure is used for sorting.

If you sort using the Sort right-click interaction, then options that allow you to select which measure to use in the sort are displayed.

How Will Sort Specifications Created in Previous Releases Be Upgraded?

In previous releases (prior to 11g) of Oracle BI EE, you could create sorts for columns in views. If you upgrade from a previous release (prior to 11g), then you might notice that the views are sorting the columns slightly differently. For information, see "Upgrading Sorts" in Oracle Fusion Middleware Upgrade Guide for Oracle Business Intelligence.
