The Previous Queries panel displays queries run by a user, with the most recently run queries displaying first.   A previous query can be reused by dragging it into the 'Query Name' box or into a group in the 'Query Tool' panel.

The 'Previous Queries' panel contains two tabs:

  • 'Previous Queries' tab: shows previous queries by descending order of time. 
  • 'Find' tab: allows user to search for a previous query.

To view more than the default of 20 queries, click on the widget with the check mark.

Maximum to Display

Queries to Display

The Maximum number of queries to display defines how many previous queries will be visible in the Previous Query view. Once the maximum number is reached the oldest query will no longer appear in the view.

 

 

TIP:

Recommendation: Use the Workplace view to save those previous queries that will be used often. In addition to being more convenient it will also prevent you from loosing a common query if the maximum number to display has been reached.

Selecting to sort By Create Date will sort the queries in the Previous Query view by the date and time the query was created. Once you select to sort by the creation date, you need to define whether or not it will be in ascending or descending order.

NOTE:

Renaming a query will not affect the sort order as the date and time is stored with the previous query.

 

 

Sort by Name

Selecting to sort By Query Name will sort the queries in the Previous Query view alphabetically by the name of the query. Once you select to sort by name, you need to define whether or not it will be in ascending or descending order.
