Archived vs On demand Reports

Question

Hi, My client is comparing newly generated on-demand reports with old archived pdfs. Some contracts that were in Active state in 2007/2008 have expired/cancelled or lapsed since then. My reports are showing latest information. Even the totals are not matching as there have been adjustments/updates to contracts over a period of time. What are the options available in this case...? Thank you.

Answer 1

select a,b,c
from table1
where :p_select=1
union
select a,b,c,sum(a,b),sum(b,c)
from table2
where :p_select=21. Actually the way you are writing query its wrong. While you are using UNION, UNION ALL, MINUS etc.. then the number of columns which are in SELECT statement should be same and also datatypes should be same.
2. The way aggregate (SUM, COUNT, AVG etc) function you are using in your query is also the wrong. You can not use two columns in one aggregate function.
3. As you are using aggregate function in your query you must have to use GROUP BY clause.
Is it possible to use different select query based on condition...just like if-then-else.? Thanks.By this sentence i can not understand what you actually want. If you can provide any example what is your data and what is your desired output then its will be better to prepare query.
But the query you use it can be like this...
select a,b,c, 0 col1, 0 col2
from table1
where :p_select=1
union
select a,b,c, NVL(sum(a),0) + NVL(SUM(b),0) col1, NVL(sum(b),0) + NVL(SUM(c),0) col2
from table2
where :p_select=2
GROUP BY A,B,CIf you problem is not getting solve by this. Then just provide any example data and what is your desired output. Then you can get the better reply.
