I use Apex oracle SQL

1). Write a SQL query that will select the department number and department name from the dept table. You will have to do a DESCRIBE on the dept table to get the actual spelling of the columns.

2. Write a SQL query that will select the employee number, employee name and job from the emp table.

3. Write a SQL query using the emp table that will return only the employees that have CLERK as their job. The columns to be included in the select are: the employee number, employee name and job.

4. Write SQL query using the emp table that shows only the employees that have a salary greater than 1250. The columns to be included in the select are: the employee number, employee name, job and salary.
