The document describes creating and testing several stored procedures in Oracle: 1) ADD_JOB inserts new jobs into the JOBS table and works correctly when invoked twice. 2) UPD_JOB updates the title of an existing job and handles exceptions when trying to update a nonexistent job. 3) DEL_JOB deletes jobs from the JOBS table and handles exceptions when trying to delete a nonexistent job. 4) QUERY_EMP retrieves an employee's salary and job ID from the EMPLOYEES table and throws an exception if an invalid employee ID is passed.
