Introduction : This pl/sql block displayes in the following fashion

column1 - value1
column2 - value2
column3 - value3

Any number of tables can be there

Usage - Save the qurey as disprec.sql
        In the sqlprompr @disprec
        Enter your statement

Limitations - Maximum output can be 1000000
              Entire sql should be typed without pressing Enter
              If any invalid column or table is present does not say which table or column
              If more throws exception ORU-100027
