Subj:   Calculate Percentages for a column
 
From:   Oscar Valles

Good morning,

I have a column with a number of hours for different offices. What I am trying to achieve is to calculate the percentage of hours for each office and display the following:

     OFFICE  |  HOURS  |  PERCENT_OF_TOTAL_HRS  |

Below is the SQL query that I thought would work.

     SELECT A1.OFFICE, SUM(A1.HOURS) AS HOURS, (SUM(A1.HOURS) / (SELECT
     SUM(A2.HOURS) FROM TABLE AS A2)) AS HRSPCT
     FROM TABLE AS A1
     WHERE A1.OFFICE LIKE 'AD%'
     GROUP BY A1.OFFICE;

When I execute this query it tells me that I am missing something by the '(' and the 'SELECT' statement. I am fairly new to Teradata and SQL so any response is greatly appreciated.


Thanks.

Oscar Valles
