I am new to SQL and SQL Server world. There must be a simple solution
to this, but I'm not seeing it. I am trying to create a crystal
report (v8.5) using a stored procedure from SQL Server (v2000) in
order to report from two databases and to enable parameters.
When I create the stored procedure, it joins multiple one-to-many
relationship tables. This results in repeated/duplicate records. Is
this an issue that should be solved within the stored procedure, or is
this inevitable? If latter, how do you eliminate the duplicates in
Crystal Reports?
Let's say we have three different tables - Event, Food, Equipment.
Each event may have multiple food and multiple equipments; some events
may not have food and/or equipments. The stored procedure outcome may
look like this:
Event Food Food_Qty Equipment
Equipment_Qty
Event1 Food2 10 Equipment5
1
Event1 Food4 10
NULL NULL
Event2 Food4 50 Equipment2
10
Event2 Food4 50 Equipment5
2
Event2 Food1 12 Equipment2
10
Event2 Food1 12 Equipment5
2
As you can see in Event2, for each Food variations, Equipment values
repeat. When I am creating a Crystal Reports, I have the duplication
problem.
What I would like to see in the report is either:
Event1
Food2, 10 Equipment5, 1
Food4, 10
Event2
Food4, 50 Equipment2, 10
Food1, 12 Equipment5, 2
OR:
Event1
Food2, 10
Food4, 10
Equipment5, 1
Event2
Food4, 50
Food1, 12
Equipment2, 10
Equipment5, 2
Attempt1: Using "Eliminate Duplicate Record" option does not work with
the Equipment section since CR does not recognize "Equipment2" in the
third line of the table and "Equipment2" in the fifth line of the
table as duplicates.
Event1 Food2, 10 Equipment5, 1
Food4, 10
Event2 Food4, 50 Equipment2, 10
Equipment5, 2
Food1, 12 Equipment2, 10
(duplication)
Equipment5, 2
(duplication)
Attempt2: I created group for each category (Event, Food, Equipment),
put the data in Group Headers and used "Suppress Section" to eliminate
if the same equipments are listed more than once within the Food
group. This eliminated the duplication, but the items do not align
correctly.
Event1 Food2, 10 Equipment5, 1
Food4, 10
Event2 Food4, 50 Equipment2, 10
Equipment5, 2
Food1, 12 (I want this to appear right below the
'Food4, 50' line)
I would really appreciate any suggestions! Thank you in advance.
Hi,
When you joined with multiple tables it will produce duplicates. One
way is to create a temp table and store the values from one table.
Let's say the Event table. Now your rows are fixed and there are no
duplicates. Then you update the remaining columns lets say you join
with the Food and Equipment table.
