Question

I have a large stored procedure that returns a record for a person, there are four fields that I need to return very specific values for. I have another stored procedure that performs this specific action.

The small stored procedure is as follows:

SELECT   TOP 1
    wea.field,
    wea.degree,
    wea.degreeyear,
    wpp.ProgramCategory
FROM dbo.webeventaffiliation wea
LEFT JOIN dbo.WebProgramParticipants wpp
    ON 
        wea.userid = wpp.UserID AND
        wea.eventid = wpp.eventid
INNER JOIN dbo.WebProgramCategoryDescriptions wpcd
    ON 
        wpcd.ProgramCategory = wpp.ProgramCategory
WHERE wea.UserID = @UserID
    ORDER BY wea.datelastmodified DESC

LARGE STORED PROCEDURE SAMPLE RETURN DATA:

Name: XXXXX
Address: XXXXX
Field: [small stored procedure value]
Degree: [small stored procedure value] 
DegreeYear: [small stored procedure value]
ProgramCategory: [small stored procedure value]

My question is how do I get the 4 data items from this stored procedure into their respective columns within the dataset that is returned from the large stored procedure?

Answer 1

Since you’re getting only one row with four values you could use OUTPUT parameters:

EXECUTE SomeSmallerProcedure
    @field OUTPUT, @degree OUTPUT, @degreeyear OUTPUT, @ProgramCategory OUTPUT;

Your procedure listed above would change to:

ALTER PROCEDURE SomeSmallerProcedure
  @field varchar(255) OUTPUT,
  @degree varchar(255) OUTPUT,
  @degreeyear varchar(255) OUTPUT,
  @ProgramCategory varchar(255) OUTPUT
AS BEGIN SET NOCOUNT ON;
  SELECT TOP 1
    @field = wea.field,
    @degree = wea.degree,
    @degreeyear = wea.degreeyear,
    @ProgramCategory = wpp.ProgramCategory
  -- ... rest as before

The signature of your procedure above would have to include those parameters explicitly for OUTPUT.
