--- where 

The `where' clause allows you to select or reject records based on
   the results of a boolean expression.

EXAMPLES:
    
          sql> where number = 70/

	  sql> where location = 'Dallas*'

          sql> where commission > salary * 12

	  sql> where dept_no = 10 and
		     [job = 'clerk*' or salary <= 1200]

          sql> where salary between 1500 and 2000

	  sql> where dept_no in <20, 30, 40>

	  sql> where job ^= 'programmer'
