Question

I have a query that returns the people in a certain household, however the individuals show up in to separate rows, what i want to do is merge the two rows into one.

SELECT     dbo.households.id, dbo.individuals.firstname, dbo.individuals.lastname
FROM         dbo.households INNER JOIN
                      dbo.individuals ON dbo.households.id = dbo.individuals.householdID
WHERE     (dbo.households.id = 10017)

Current results:

ID | First Name | Last Name |
1  | Test       | Test1     |
1  | ABC        | ABC1      |

Desired results:

ID | First Name | Last Name |ID1| First Name1| Last Name1|
1  | Test       | Test1     |1  | ABC        | ABC1      |

However if theres 3 people then it would need to merge all 3 and so on

Answer 1

Depending on the response to the question I asked above, below is a simple script that would compile the names into a string and then output the string (I don’t have access to the syntax validator now so forgive any errors):

DECLARE 
    @CNT INT,
    @R_MAX INT,
    @H_ID INT,
    @R_FIRST VARCHAR(250),
    @R_LAST VARCHAR(250),
    @R_NAMES VARCHAR(MAX)

SET @CNT = 0; --Counter
SET @R_NAMES = 'Names: ';
SELECT @R_MAX = COUNT(*) FROM dbo.individuals a WHERE a.householdID = @H_ID; --Get total number of individuals
PRINT(@R_MAX); --Output # of matching rows
--Loop through table to get individuals
WHILE @CNT < @R_MAX
    BEGIN
        --Select statement
        SELECT * FROM (SELECT
            @R_FIRST = b.firstname,
            @R_LAST = b.lastname,
                       ROW_NUMBER() OVER (ORDER BY b.lastname, b.firstname) AS Row
        FROM
            dbo.households a INNER JOIN
            dbo.individuals b ON a.id = b.householdID 
        WHERE
            (a.id = @H_ID)) AS RN WHERE (Row = @CNT);

        SET @R_NAMES = @R_NAMES + @R_FIRST + @R_LAST + '; '; --Add individual's name to name string
              PRINT(CAST(@CNT AS VARCHAR) + ':' + @R_NAMES);
        SET @CNT = @CNT +1; --Increase counter
    END

PRINT(@R_NAMES); --Output the individuals
