Hi

How can I combine the bcClass.Description and bcBrands.Description fields into one field. There will only be a value in on of the two fields.

SELECT        bcGraderings.Aantal AS Qty, bcGraderings.Class AS sClass, bcGraderings.MG AS MassGrp, bcGraderings.Mass, bcGraderings.Product, bcGraderings.ISO AS Salesbrand, bcClass.Description, 
                         bcBrands.Description AS Expr1
FROM            bcGraderings LEFT OUTER JOIN
                         bcBrands ON bcGraderings.ISO = bcBrands.Code LEFT OUTER JOIN
                         bcClass ON bcGraderings.ISO = bcClass.Code
WHERE        (bcGraderings.gDate > '2014-09-01 00:00:00.000')

Open in new window


Here is an example of the data that is returned with the query

Qty      sClass      MassGrp      Mass      Product      Salesbrand      Description      Expr1
1      M      2      14      SA1      M      Group 1      NULL
1      M      1      8,5      SA1      M      Group 1      NULL
1      M      1      11,5      SA0      M      Group 2      NULL
1      M      4      22      SC2      M      Group 2      NULL
1      D      3      16,5      SA2      N      NULL      Class 1
1      D      3      16,8      SA2      N      NULL      Class 2

Like this:
SELECT        bcGraderings.Aantal AS Qty, bcGraderings.Class AS sClass, bcGraderings.MG AS MassGrp, bcGraderings.Mass, bcGraderings.Product, bcGraderings.ISO AS Salesbrand, ISNULL(bcClass.Description,                          bcBrands.Description) AS Description
FROM            bcGraderings LEFT OUTER JOIN
                         bcBrands ON bcGraderings.ISO = bcBrands.Code LEFT OUTER JOIN
                         bcClass ON bcGraderings.ISO = bcClass.Code
WHERE        (bcGraderings.gDate > '2014-09-01 00:00:00.000')
