Oracle 19c Version

From the 2019/20 Academic year we will be using Oracle 19c.

Oracle 12c should only be used by MSc students who are completing their projects.

The purpose of this Wiki is to introduce using SQL from the Oracle database management system (DBMS). It is intended to be supplemented by a lecture course.

Commands to try out are in a box, for example:


There will be exercises for you to try out too. In most cases you will be given the results so you can check your answer. These will also be presented in a blue font, for example:

    DEPTNO DNAME          LOC
---------- -------------- -------------
        10 ACCOUNTING     NEW YORK
        20 RESEARCH       DALLAS
        30 SALES          CHICAGO
        40 OPERATIONS     BOSTON

Things to note:

  • when running the commands in Oracle you will need to press RETURN after each line.
  • the order of the results may differ from yours. The key thing is that you have the same rows, but not necessarily in the same order.

Menu options (Windows) that involve more than one step will be shown as a sequence, separated by the greater than symbol (>), for example:


Means select File from the main Window menu then Open from the submenu

If you spot any errors in this workbook, please inform the Oracle DBA: Mary Garvey
