You use Summarize Script to view a summary of the actions that the script will perform, in the order in which they will occur.

   SQL Refactor uses a tree structure to group blocks of code. For example, the keywords within a CREATE statement are grouped together. To expand a block, click  or double-click the keyword.
   When you select a keyword in the summary, it is highlighted in the query editor. If you click on the main keyword for a block, the block is highlighted in the query editor.
   The following symbols are used to draw your attention to commands that change the context:

   	USE commands
   	SETUSER, EXECUTE AS LOGIN, and REVERT commands

   You can resize the dialog box to view more of the summary, if required.

3. Click Close to close the summary.
