The Copy Compare Tool provides users a method of depicting differences in the content of the clipboard history. All comparisons are displayed in the Copy Compare Results tab.

To compare two items copied to the clipboard history

• Alternatively, launch the Copy History Compare Tool from within the SQL History and SQL Archive tool. This allows comparison of the contents of queries stored in the SQL History and SQL Archive. Select two items with CTRL/Command+Click enables the comparison with the button to the left of the "Max History".
  

The results of a comparison display as a split-pane and connecting splines for identifying where the deletions, changes and additions occur. Each file in a comparison takes up half of the comparison results window. At the top right-side of the window, view the total number of differences discovered. Comparisons show the character differences in a modified line with bolding and background color highlights indicate modified blocks. If the files are not identical, the differences are highlighted by default in pink (deleted), purple (changed) or green (added). You can change the colors for the difference highlighting from the Options dialog.

This table describes the Toolbar actions in the Copy Compare Results tab.
