I think you were looking for a UNION ALL

DECLARE @TableA TABLE(
        ID INT,
        Category VARCHAR(50)
)

INSERT INTO @TableA (ID,Category) SELECT 1, 'Books'
INSERT INTO @TableA (ID,Category) SELECT 2, 'Fruits'
INSERT INTO @TableA (ID,Category) SELECT 3, 'Vegetables'

DECLARE @TableB TABLE(
        ID INT,
        CategoryID INT,
        Item VARCHAR(50)
)


INSERT INTO @TableB (ID,CategoryID,Item) SELECT 1,1,'Rytham of Music'
INSERT INTO @TableB (ID,CategoryID,Item) SELECT 2,1,'My Biography'
INSERT INTO @TableB (ID,CategoryID,Item) SELECT 3,1,'Jungal Book'
INSERT INTO @TableB (ID,CategoryID,Item) SELECT 4,2,'Apple'
INSERT INTO @TableB (ID,CategoryID,Item) SELECT 5,2,'Orenge'
INSERT INTO @TableB (ID,CategoryID,Item) SELECT 6,2,'Pinnaple'
INSERT INTO @TableB (ID,CategoryID,Item) SELECT 7,3,'Spinach'

SELECT  ID,
        MergedCategory
FROM    (
            SELECT  ID,
                    Category + ' -- From TableA' MergedCategory,
                    CAST(ID AS VARCHAR(10)) + '\' AS CategoryID
            FROM    @TableA
            UNION ALL
            SELECT  ID,
                    Item,
                    CAST(CategoryID AS VARCHAR(10)) + '\' + CAST(ID AS VARCHAR(10)) + '\'
            FROM    @TableB
        ) sub
ORDER BY CategoryID
