SQL and a backlog report by site

Question

Hi, I had to create a backlog reprort a few months back and the only way I could get the data to organize properly was to create a sql statement that had the months predefined as below: SELECT  sum(1),  '2006-10',  SEA_ERSSQL.dbo.HD_CALL.CALL_IDFROM  SEA_ERSSQL.dbo.HD_CALLWHERE  (   substring(CONVERT(VARCHAR,SEA_ERSSQL.dbo.HD_CALL.CREATION_TIME, 120),1,7)  <  '2006-10'   AND   (    SEA_ERSSQL.dbo.HD_CALL.CONDITION  <>  'Closed'    OR    substring(CONVERT(VARCHAR,SEA_ERSSQL.dbo.HD_CALL.CLOSE_DATE, 120),1,7)  >=  '2006-10'   )  )GROUP BY  substring(CONVERT(VARCHAR,SEA_ERSSQL.dbo.HD_CALL.CREATION_TIME, 120),1,7),   SEA_ERSSQL.dbo.HD_CALL.CALL_IDUnionSELECT  sum(1),  '2006-11',  SEA_ERSSQL.dbo.HD_CALL.CALL_IDFROM  SEA_ERSSQL.dbo.HD_CALLWHERE  (   substring(CONVERT(VARCHAR,SEA_ERSSQL.dbo.HD_CALL.CREATION_TIME, 120),1,7)  <  '2006-11'   AND   (    SEA_ERSSQL.dbo.HD_CALL.CONDITION  <>  'Closed'    OR    substring(CONVERT(VARCHAR,SEA_ERSSQL.dbo.HD_CALL.CLOSE_DATE, 120),1,7)  >=  '2006-11'   )  )GROUP BY  substring(CONVERT(VARCHAR,SEA_ERSSQL.dbo.HD_CALL.CREATION_TIME, 120),1,7),   SEA_ERSSQL.dbo.HD_CALL.CALL_IDUnionSELECT  sum(1),  '2006-12',  SEA_ERSSQL.dbo.HD_CALL.CALL_IDFROM  SEA_ERSSQL.dbo.HD_CALLWHERE  (   substring(CONVERT(VARCHAR,SEA_ERSSQL.dbo.HD_CALL.CREATION_TIME, 120),1,7)  <  '2006-12'   AND   (    SEA_ERSSQL.dbo.HD_CALL.CONDITION  <>  'Closed'    OR    substring(CONVERT(VARCHAR,SEA_ERSSQL.dbo.HD_CALL.CLOSE_DATE, 120),1,7)  >=  '2006-12'   )  )GROUP BY  substring(CONVERT(VARCHAR,SEA_ERSSQL.dbo.HD_CALL.CREATION_TIME, 120),1,7),   SEA_ERSSQL.dbo.HD_CALL.CALL_ID
What I'm being asked to do now is to create a backlog
report based on sites.  We have several hundred that are grouped by a
condition called Site ID.  I originally tried modifying the SQL dates only
but soon realized I would need a way for the SQL to accommodate the ongoing
changes since the person running the report could choose one site or one
hundred and the predefined SQL would not change to allow for these
changes.  Does anyone have any ideas on how to build a backlog report that
would provide the same results but allow variables or allow that piece of the
SQL to be modified?

si,
If you have 10 queries that each return a single value, you could combine them into one big query.
Each of your 10 queries could be a scalar subquery.
e.g:
SQL> select (select 1 from dual) A,
  2         (select 2 from dual) B,
  3         (select 3 from dual) C
  4    from dual;
         A          B          C                                               
         1          2          3  Then your report or chart could run off of that query.
