For some databases the Explain Plan information is shown in the Visual Explain window. This provides a method of easily understanding how the database will process your query.
This feature is currently available for DB2/LUW, Oracle, SQL Server and PostreSQL.
It can also be used with DB2 z/OS if the Options > Explain > Use Visual Explain for DB2 z/OS has been selected. Configuration of this feature for DB2 z/OS has not been completed so should be used with caution.
