After writing and executing a SQL query using SQL Developer, the results of the query obtained from the database can be presented to us in either a grid or script view. In this video, view the output of a query.
- [Instructor] Note that once you write…and execute SQL queries throughout this course…using Oracle SQL Developer,…the output or result set of the SQL query…will be displayed in the bottom pane of your screen…under the query results tab.…In addition to providing…the actual query results themselves,…which will include the column names…as well as the actual records,…you will also see how many rows…have been retrieved from the database…and how long it took to retrieve those rows.…
Remember that what you see on the screen right now…is a partial result.…And you can scroll down to see a complete result…of all of the records that were retrieved…as part of your SQL query.…Also note that some columns…especially for very wide tables…that contain a lot of columns might be hidden.…And you will have to scroll to the right to see them.…Also note that you can refresh the output…by clicking on the refresh button.…And clicking on the SQL button will give you the SQL command…that was used to display the output that you see…in the bottom grid…
