Question

![Cognost reports studio Query Explorer]
Below is the snapshot of a table.
**Acctno ClientNo ClientName PrimaryOffId SecondaryOffID**
101 11111 ABC corp 3 Not Defined
102 11116 XYZ Inc 5 Not Defined
103 11113 PQRS Corp 2 9
104 55555 Food LLC 4 11
105 99999 Kwlg Co 1 Not Defined
106 99999 Kwlg Co 1 Not Defined
107 11112 LMN Corp Not Defined 6
108 11112 LMN Corp Not Defined 6
109 11115 Sleep Co 4 10
110 44444 Cool Co Not Defined 8
111 11114 Sail LLC 3 Not Defined
112 66666 Fun Inc 1 Not Defined
113 88888 Job LLC 5 12
114 22222 Acc Co Not Defined Not Defined
115 77777 Good Corp 2 Not Defined
116 33333 City LLC Not Defined 7
117 33333 City LLC Not Defined 7
118 33333 City LLC Not Defined 7
119 11111 ABC corp 3 Not Defined
I want to replace PrimaryOffID and SecondaryOffID with their Names coming from this table
EmpID Names
1 Cathy
2 Chris
3 John
4 Kevin
5 Mark
6 Celine
7 Jane
8 Phil
9 Jess
10 Jose
11 Nick
12 Rosy
The Result should look like this: Notice that, If Cathy is the PrimaryOfficer, she can't be the Secondary Officer and vice versa. This logic is applicable for all the Names
Acctno ClientNo Client Name PrimOffName SecondaryOffName
101 11111 ABC corp John Not Defined
102 11116 XYZ Inc Mark Not Defined
103 11113 PQRS Corp Chris Jess
104 55555 Food LLC Kevin Nick
105 99999 Kwlg Co Cathy Not Defined
106 99999 Kwlg Co Cathy Not Defined
107 11112 LMN Corp Not Defined Celine
108 11112 LMN Corp Not Defined Celine
109 11115 Sleep Co Kevin Jose
110 44444 Cool Co Not Defined Phil
111 11114 Sail LLC John Not Defined
112 66666 Fun Inc Cathy Not Defined
113 88888 Job LLC Mark Rosy
114 22222 Acc Co Not Defined Not Defined
115 77777 Good Corp Chris Not Defined
116 33333 City LLC Not Defined Jane
117 33333 City LLC Not Defined Jane
118 33333 City LLC Not Defined Jane
119 11111 ABC corp John Not Defined
But Instead it looks like this:
Acctno ClientNo ClientName PrimOffName SecondaryOffName
101 11111 ABC corp John Not Defined
102 11116 XYZ Inc Mark Not Defined
103 11113 PQRS Corp Chris Not Defined

109 11115 Sleep Co Kevin Not Defined
109 11115 Sleep Co Not Defined Jose
110 44444 Cool Co Not Defined Phil
111 11114 Sail LLC John Not Defined
112 66666 Fun Inc Cathy Not Defined
113 88888 Job LLC Mark Not Defined
113 88888 Job LLC Not Defined Rosy
114 22222 Acc Co Not Defined Not Defined
115 77777 Good Corp Chris Not Defined
116 33333 City LLC Not Defined jane
117 33333 City LLC Not Defined jane
118 33333 City LLC Not Defined jane
119 11111 ABC corp John Not Defined
Notice that, now the Acctno is no more unique, Where ever the Names should have been in both the fields together, it separates and gives the output in the next row creating multiple records. i tried various options but it didn't work. Please be aware, that I am creating this report in Cognos Studio. Please suggest the possible query to get the desired result. Thanks in Advance. Appreciate your help.

Answer 1

You don't state which version of Cognos you're using. "Cognos Studio" is ambiguous. I'm most familiar with 8.4.1, but even then you don't say if you're trying to define this in the Cognos model, Query Studio, Event Studio or Report Studio.
Second, you should always show what you've got so far when asking questions on StackOverflow. People want to see what you have done to show you want to fix, not repeat the lion's share of the work. That's why you got downvotes.
As far as plain SQL, you'll want to do this:
SELECT a.Acctno, a.ClientNo, a.ClientName, coalesce(e1.Names,'Not Defined') "PrimaryOffName", coalesce(e2.Names,'Not Defined') "SecondaryOffName"
FROM Account a
LEFT OUTER JOIN Emp e1
ON t.PrimaryOffID = e1.EmpID
LEFT OUTER JOIN Emp e2
ON t.PrimaryOffID = e2.EmpID
I made up table names. You can do this in Report Studio by creating two queries for Emp and outer joining them in succession to the Account query.
If you're able to, you'll want to move the OffID fields to a separate juntion table and remove them from the Account table. You can then create a Status field or flag in that junction table that identifies primary and secondary.
