SQL Developer provides us with a visual way to explore the different objects created in our database schema. In this video, learn how to view tables created in an Oracle schema and view their structure and data.
- [Instructor] Using SQL developer…you can easily view all of the tables…which have been created in the Oracle schema…to which you are connected to.…All you have to do is extend the tables folder…under your database connection.…So in our case we have an HR connection…to the HR schema.…Extending it we see the tables folder.…Under it you see a list of all of the tables…that have been created in this schema.…For example, we see an employees…and departments table, which we'll be using…heavily throughout this course.…
Clicking on each one of these tables…will provide us with additional information.…For example, we see the table structure,…the various column names that make up this table,…as well as their datatypes.…We learn more about datatypes…later in our course.…Note that in addition to the new tab…that just opened with the table name…we also have a row of sub tabs.…For example, clicking on the data sub tab…will show us the data that's currently stored…in our employees table.…
You can always close the tab…and reopening it by double clicking…
