If after this query ran (or even after a GO statement), you again ran only the SELECT * FROM cteEmployees statement, you would get an error: Invalid object name 'cteEmployees' It no longer exists The preceding example also shows the basic syntax structure for a CTE:

While a CTE can be recursive or nonrecursive, one of the great strengths of a CTE is its ability to reference itself and create a recursive CTE A recursive CTE will be repeatedly executed until a complete result set is obtained This is commonly done when accessing hierarchical data, such as when displaying employees in an organizational chart EXAM TIP When hierarchical data needs to be displayed from a table that references itself, consider using a CTE to recursively access the table A recursive query is one that references a recursive CTE Three common examples of using recursive CTEs are 1) when creating an organizational chart of employees to show who reports to whom; 2) when creating a bill of materials where some parts are referred to as parents with subcomponents associated with them; and 3) when products are associated to parent categories The recursive CTE can loop through the data and return a hierarchical display In earlier versions of SQL Server, the functionality of a recursive CTE was created by using temporary tables, cursors, and complex logic In SQL Server 2005, the use of a recursive CTE makes this logic much simpler

Notice that the CTE query has two definitions The first one (the anchor member) defines the query referencing the external table It is followed by a UNION, UNION ALL, EXCEPT, or INTERSECT statement The next CTE definition references the CTE recursively During the execution of the recursive CTE, the second query definition is run repeatedly until an empty set is returned In the following exercise, we ll create a table, populate it with data that can be arranged hierarchically, and then use a recursive CTE to retrieve and display the data

Exercise 49: Use a CTE 1 Open a New Query window within SSMS 2 Use the following script to create an Employees table in the 4 database
USE 4; GO CREATE TABLE dboLincolnCabinet ( LincolnCabinetID int IDENTITY (100,1) NOT NULL, LastName varchar(50) NULL, FirstName varchar(50) NULL, MgrId int NULL references dboLincolnCabinet, Title varchar(50) NULL CONSTRAINT PK_LincolnCabinetID PRIMARY KEY (LincolnCabinetID) );
Note that the MgrID references the LincolnCabinetID (the PK in the LincolnCabinet table) 3 With the table created, let s populate it with the following INSERT statements
INSERT INTO LincolnCabinet (LastName, FirstName, MgrID, Title) VALUES('Lincoln', 'Abraham', Null, 'President') INSERT INTO LincolnCabinet (LastName, FirstName, MgrID, Title) VALUES('Stanton', 'Edwin', 100, 'Secretary of War') INSERT INTO LincolnCabinet (LastName, FirstName, MgrID, Title) VALUES('Seward', 'William', 100, 'Secretary of State') INSERT INTO LincolnCabinet (LastName, FirstName, MgrID, Title) VALUES('Welles', 'Gideon', 100, 'Secretary of the Navy') INSERT INTO LincolnCabinet (LastName, FirstName, MgrID, Title) VALUES('Welles', 'Orson', 103, 'Grandson')
This shows President Abraham Lincoln at the top of the list as the President Notice that the MgrID is Null since he doesn t directly report to any single person Secretary of War Stanton, Secretary of State Seward, and the Secretary of the Navy all report directly to the President Orson Welles was the grandson of Gideon Welles, so for the fun of it, we re putting him as reporting to Secretary of the Navy Gideon Welles 4 With this done, let s query the table with a CTE This CTE will allow us to recursively query the table to determine who works for whom in the hierarchy
USE 4; GO WITH cteReport (HierarchyOrder, MgrID, LincolnCabinetID, LastName, Title) AS (-- Anchor member definition SELECT 0 AS HierarchyOrder, lcMgrID, lcLincolnCabinetID, lcLastName, lcTitle FROM LincolnCabinet AS lc WHERE MgrID IS NULL UNION ALL -- Recursive member definition SELECT dHierarchyOrder + 1, lcMgrID, lcLincolnCabinetID, lcLastName, lcTitle
