Plan Help

The access plan help provides online help for each operation within the access plan to help you understand each step of the plan.

To view the help for an operation

Right-click the access plan step for which you want help and select Get help on operation_name.

 

Animate Access Plans

You can have the steps in the access plan highlighted one-by-one in the order they are executed.

To animate the plan or cancel the animation

Right-click the Access Plan pane and select Animate Plan Steps.

 

Copy Access Plans

You can copy the access plan to the clipboard.

To copy an access plan

Right-click the Access Plan pane and select Copy.

When the access plan is displayed as Tree Plan or Plain Language Plan, the access plan can be pasted as text or as a bitmap picture. Graphic applications, such as MS Paint, only paste the access plan as a bitmap. Text applications, such as Notepad, only paste it in a text format. Applications that handle both text and graphics, such as Microsoft Word, allow you to choose the format if you select the Paste Special option to paste the image.

 

DB2 Optimized Text

The DB2 Optimized Text shows the reconstructed SQL provided by DB2 and is retrieved at the same time the access plan is retrieved.
