How can I get all the rows from master table and relevent row from the detail table in MS-SQL? - vb.net

Question

I am using MS-SQL and I am trying to write a query which fetches rows from the master table and related rows from the detail table. Now, the thing I want is that it must only fetch the first row from the master table and related field from the detail tables should be blank in that first row, now if there are related rows found in the detail tables, they must be shown in the separate rows. I have been trying using the following query but it is not giving the desired result.
SELECT
DISTINCT
ProductMaster.ProductMasterID, ProductMaster.ProductName,
ProductMaster.SubCategoryID, SubCategory.SubCategoryName,
ProductBrandAndType.ProductBranAndTypeID, ProductBrandAndType.ProductType,
ProductBrandAndType.Brand, ProductMaster.ProductDesc,
ProductMaster.ReOrderLevel
FROM
ProductBrandAndType
RIGHT OUTER JOIN
Inward
ON ProductBrandAndType.ProductBranAndTypeID = Inward.ProductBrandAndTypeID
RIGHT OUTER JOIN
ProductMaster
ON Inward.ProductID = ProductMaster.ProductMasterID
LEFT OUTER JOIN
SubCategory
ON ProductMaster.SubCategoryID = SubCategory.SubCategoryID
ORDER BY
ProductMaster.ProductName,
ProductBrandAndType.ProductType,
ProductBrandAndType.Brand;
Can anyone help me on this?

Following query worked.
SELECT dbo.ProductMaster.ProductMasterID, dbo.ProductMaster.ProductName, dbo.ProductMaster.SubCategoryID, dbo.ProductMaster.ProductDesc,
dbo.ProductMaster.ReOrderLevel, null as ProductBrandAndTypeID,
null AS Type, null as Brand
FROM dbo.ProductBrandAndType RIGHT OUTER JOIN
dbo.Inward ON dbo.ProductBrandAndType.ProductBranAndTypeID = dbo.Inward.ProductBrandAndTypeID RIGHT OUTER JOIN
dbo.ProductMaster ON dbo.Inward.ProductID = dbo.ProductMaster.ProductMasterID LEFT OUTER JOIN
dbo.SubCategory ON dbo.ProductMaster.SubCategoryID = dbo.SubCategory.SubCategoryID
UNION
SELECT dbo.ProductMaster.ProductMasterID, dbo.ProductMaster.ProductName, dbo.ProductMaster.SubCategoryID, dbo.ProductMaster.ProductDesc,
dbo.ProductMaster.ReOrderLevel, dbo.ProductBrandAndType.ProductBranAndTypeID,
dbo.ProductBrandAndType.ProductType, dbo.ProductBrandAndType.Brand
FROM dbo.ProductBrandAndType RIGHT OUTER JOIN
dbo.Inward ON dbo.ProductBrandAndType.ProductBranAndTypeID = dbo.Inward.ProductBrandAndTypeID RIGHT OUTER JOIN
dbo.ProductMaster ON dbo.Inward.ProductID = dbo.ProductMaster.ProductMasterID LEFT OUTER JOIN
dbo.SubCategory ON dbo.ProductMaster.SubCategoryID = dbo.SubCategory.SubCategoryID
ORDER BY ProductName;

If you just what the first row from the ProductMaster. Then you can do something like this:
;WITH CTE
(
SELECT
ROW_NUMBER() OVER(ORDER BY ProductMaster.ProductMasterID) AS RowNbr,
ProductMaster.ProductName,
ProductMaster.SubCategoryID,
ProductMaster.ProductDesc,
ProductMaster.ReOrderLevel
FROM
ProductMaster
)
SELECT
ProductMaster.ProductMasterID,
ProductMaster.ProductName,
ProductMaster.SubCategoryID,
SubCategory.SubCategoryName,
ProductBrandAndType.ProductBranAndTypeID,
ProductBrandAndType.ProductType,
ProductBrandAndType.Brand,
ProductMaster.ProductDesc,
ProductMaster.ReOrderLevel
FROM
ProductBrandAndType
RIGHT OUTER JOIN Inward
ON ProductBrandAndType.ProductBranAndTypeID = Inward.ProductBrandAndTypeID
RIGHT OUTER JOIN CTE AS ProductMaster
ON Inward.ProductID = ProductMaster.ProductMasterID
AND RowNbr=1
LEFT OUTER JOIN SubCategory
ON ProductMaster.SubCategoryID = SubCategory.SubCategoryID
ORDER BY
ProductMaster.ProductName,
ProductBrandAndType.ProductType,
ProductBrandAndType.Brand;
