  I have a table called

  Employee(ID,Name,Age,Country,Manager,Status);

  And the values are as follows -

  (1,'Ravi',29,'IN','Anil','A')

  (2,'Balaji',30,'IN','Siju','A')

  (3,'Sanjeev',31,'IN','Venkat','A')

  I need a select query to get results as follows -

  1,'Ravi',29,'IN'

  1,'Ravi',29,'Anil'

  1,'Ravi',29,'A'

  2,'Balaji',30,'IN'

  2,'Balaji',30,'Siju'

  2,'Balaji',30,'A'

  3,'Sanjeev',31,'IN'

  3,'Sanjeev',31,'Venkat'

  3,'Sanjeev',31,'A'

  Can anybody help here to write the select query.

  Thanks,

  Ravi.

  DROP TABLE #Employee

  CREATE TABLE #Employee (ID INT, Name VARCHAR(10), Age INT, Country CHAR(2), Manager VARCHAR(10), Status CHAR(1));

  INSERT INTO #Employee (ID, Name, Age, Country, Manager, Status)

  SELECT 1,'Ravi',29,'IN','Anil','A' UNION ALL

  SELECT 2,'Balaji',30,'IN','Siju','A' UNION ALL

  SELECT 3,'Sanjeev',31,'IN','Venkat','A'

  SELECT ID, Name, Age, NewColumn

  FROM ( -- derived table is unnecessary if Seq is acceptable in output

  SELECT ID, Name, Age, NewColumn = CAST(Country AS VARCHAR(10)), 1 AS Seq

  FROM #Employee

  UNION ALL

  SELECT ID, Name, Age, NewColumn = CAST(Manager AS VARCHAR(10)), 2 AS Seq

  FROM #Employee

  UNION ALL

  SELECT ID, Name, Age, NewColumn = CAST(Status AS VARCHAR(10)), 3 AS Seq

  FROM #Employee

  ) d

  ORDER BY ID, Seq
