hierarchical query clause
The conversion of the following Oracle hierarchical query syntaxes to
Common table expression (WITH clause) in DB2,SQL Server 2000 and SQL
Server 2005 are supported .
a. Select Query Statement with START WITH ...CONNECT BY PRIOR clause
Example ::
Source Oracle Query :
SELECT parent1,child FROM hierrarchy START WITH parent1 =
1 CONNECT BY PRIOR parent1=child;
SwisSQL Converted Query to DB2 and SQL Server 2005 :
WITH ADV_RECURSIVE(parent1,child) AS (SELECT
PARENT.parent1, PARENT.child FROM hierrarchy PARENT
WHERE PARENT.parent1 = 1
UNION ALL
SELECT CHILD.parent1,CHILD.child FROM ADV_RECURSIVE PARENT,
hierrarchy CHILD WHERE CHILD.child
= PARENT.parent1)
SELECT parent1, child FROM ADV_RECURSIVE
SwisSQL Converted Query to SQL Server 2000 :
/******************* BEGIN START WITH CONNECT BY
CONVERSION *********************/
CREATE
FUNCTION sp_hierrarchy_hierarchy1(@current varchar(2000))
RETURNS @ctest
TABLE ( PARENT1 numeric(22), CHILD numeric(22), level int, rownum int
IDENTITY(1,1))
AS
BEGIN
DECLARE @prior varchar(2000)
DECLARE @ctest1 TABLE ( PARENT1 numeric(22), CHILD
numeric(22), level int)
DECLARE @PARENT1 numeric(22)
DECLARE

DECLARE @level int ;
DECLARE cur CURSOR FOR select * from hierrarchy
where parent1 = @current
SELECT @level = 1;
WHILE (1=1)
BEGIN
IF EXISTS(SELECT parent1 FROM
hierrarchy WHERE child = @current)
BEGIN
SELECT @prior

SELECT

SELECT @level

INSERT INTO

/******************* END START WITH CONNECT BY
CONVERSION ********************/
SELECT
parent1,
child
FROM DBO.sp_hierrarchy_hierarchy1(1) ;
b. Select Query Statement with START WITH ...CONNECT BY PRIOR clause
and LEVEL pseudo column
Example ::
Source Oracle Query :
select parent1,child,level from hierrarchy start with parent1=1 connect
by prior parent1=child
SwisSQL converted query to DB2 and SQL Server 2005 :
WITH
ADV_RECURSIVE(parent1,child,level) AS (SELECT
PARENT.parent1, PARENT.child,1 FROM hierrarchy PARENT
WHERE PARENT.parent1 = 1
UNION ALL
SELECT CHILD.parent1,CHILD.child,LEVEL+1 FROM ADV_RECURSIVE
PARENT, hierrarchy CHILD WHERE CHILD.child = PARENT.parent1)
SELECT parent1, child, level FROM ADV_RECURSIVE
SwisSQL converted query to SQL Server 2000 :
/******************* BEGIN START WITH CONNECT BY
CONVERSION *********************/
CREATE
FUNCTION sp_hierrarchy_hierarchy1(@current varchar(2000))
RETURNS @ctest
TABLE ( PARENT1 numeric(22), CHILD numeric(22), level int, rownum int
IDENTITY(1,1))
AS
BEGIN
DECLARE @prior varchar(2000)
DECLARE @ctest1 TABLE ( PARENT1 numeric(22), CHILD
numeric(22), level int)
DECLARE @PARENT1 numeric(22)
DECLARE @CHILD numeric(22)
DECLARE @level int ;
DECLARE cur CURSOR FOR select * from hierrarchy
where parent1 = @current
SELECT @level = 1;
WHILE (1=1)
BEGIN
IF EXISTS(SELECT parent1 FROM
hierrarchy WHERE child = @current)
BEGIN
SELECT @prior
= @current
SELECT
@current = parent1 FROM hierrarchy WHERE child = @prior
SELECT @level
= @level + 1;
INSERT INTO
@ctest1 SELECT *, @level FROM hierrarchy where parent1 = @current AND
child = @prior
CONTINUE
END
ELSE
BREAK
END
OPEN cur
FETCH NEXT FROM cur INTO @PARENT1,@CHILD
WHILE ( @@FETCH_STATUS = 0)
BEGIN
INSERT INTO @ctest
VALUES(@PARENT1,@CHILD, 1)
INSERT INTO @ctest SELECT * FROM
@ctest1
FETCH NEXT FROM cur INTO
@PARENT1,@CHILD
END
RETURN
END
GO
/******************* END START WITH CONNECT BY
CONVERSION ********************/
SELECT
parent1,
child,
level
FROM DBO.sp_hierrarchy_hierarchy1(1)
c. Select Query Statement with START WITH...CONNECT BY clause
Example ::
SELECT employee_id, manager_id, first_name, last_name
FROM employee
START WITH employee_id = 1
CONNECT BY employee_id = manager_id;
