#327003

I'm using two cases separately to display the result as two columns, but I'm getting the result of only first case.
I have a table with a column member_type_id. This column has two sets of values 11 and 99. I want to group my entire table based on those two values.
SELECT CASE
   WHEN MEMBER_TYPE_ID = 11 THEN COUNT(MEMBER_TYPE_ID) OVER (PARTITION BY MEMBER_TYPE_ID)
   END emp_count,
   CASE
   WHEN MEMBER_TYPE_ID = 99 THEN COUNT(MEMBER_TYPE_ID) OVER (PARTITION BY MEMBER_TYPE_ID)
   END sp_count
FROM main

Can you kindly provide more details along with sample data and also what you mean by I'm getting the result of only first case?

Expected result set is also important. Have a look at the link in my signature on how to post T-SQL questions.

Thanks.

Create table main
(name varchar,
member_type_id integer)

Following are the values in main table.
Name member_type_id
Sara 11
Jack 11
Jill 99
Mary 99
Anna 99

SELECT CASE
WHEN MEMBER_TYPE_ID = 11 THEN COUNT(MEMBER_TYPE_ID) OVER (PARTITION BY MEMBER_TYPE_ID)
END emp_count,
CASE
WHEN MEMBER_TYPE_ID = 99 THEN COUNT(MEMBER_TYPE_ID) OVER (PARTITION BY MEMBER_TYPE_ID)
END sp_count
FROM main
When I run the above query in sql server I get following result
emp_count
2
2
sp_count
3
3
3
However, when I run this query in crystal report, I get the result of only emp_count i.e 2. For sp_count nothing shows. I think the issue is with how crystal is reading the case statement. I don't know if this is the right place for me to ask this question. However, any help will be greatly appreciated. Thanks in advance.

You mentioned MEMBER_TYPE_ID = 99 for sp_count column in case statement. However in test data it is member_type_id=22.
Can you kindly confirm which is correct?

While typing I accidentally put 22 instead of 99. I've edited my numbers.

Out of interest, why are you using a OVER clause, rather than a GROUP BY?

I have a complex query where I'm grouping by different items. To keep the grouping separate, I'm using partition over by clause.

What makes you think that the problem is with the CASE expression? Something else in your query may be filtering out the rows for the spouses?

Also, this CANNOT be the results that you are getting when you run this, because you should be getting TWO columns per row and you are only showing ONE column per row.

Unfortunately, when you try to obfuscate what is considered non-essential parts of a query, you often end up with a totally different issue. I'm fairly certain that there's some other problem with what is being done. I suspect that the Crystal Report has it's own grouping somewhere in the report or something else that is inherent to the report, such as accidentally choosing the same column twice. Or perhaps not realizing that you didn't place one of those two columns in the report, and thus only got one in the results. You have to be sure the second column is actually in the report somewhere, and on the same detail line as the other column (at least most of the time, this is how you typically do that)...
