Through this view, you can also access the actual analyzed data via the data explorer.
To access the analyzed data rows, right-click any of the lines in the table and select:

|---|---|
| View match rows | access a list of all rows that could be matched in the two identical column sets |
| View not match rows | access a list of all rows that could not be matched in the two identical column sets |

Information noteWarning: The data explorer does not support connections which
has empty user name, such as Single sign-on of MS SQL Server. If you analyze
data using such connection and you try to view data rows in the
Data Explorer
perspective, a warning message
prompt you to set your connection credentials to the SQL Server.
The figure below illustrates in the data explorer the list of all analyzed rows in the two columns.
From the SQL editor, you can save the executed query and list it under the folders in the DQ Repository tree view if you click the save icon on the editor toolbar. For more information, see Saving the queries executed on indicators.
