SQL ServerからOracleへの変換

Question

このSQL ServerコードをOracleコードに変換できません。私はSQLの専門家ではない、誰もこのOracleの互換性にこのコードを変換することができます。

Declare @lvl as int 
Declare @rows as int 
DECLARE @foo as Table(
    KV_MANAGERNR int, 
    KV_PERSONNR varchar(10), 
    ord int, 
    lvl int) 

INSERT @foo (KV_MANAGERNR, KV_PERSONNR, ord, lvl) 
select KV_MANAGERNR, KV_PERSONNR, row_number() over(order by KV_PERSONNR), 0 
    from PERSONSMANAGER where KV_MANAGERNR='127723' 

set @rows=@@ROWCOUNT 
set @lvl=0 

--Do recursion 
WHILE @rows > 0 
BEGIN 
    set @lvl = @lvl + 1 

    INSERT @foo (KV_MANAGERNR, KV_PERSONNR, ord, lvl) 
    SELECT DISTINCT b.KV_MANAGERNR, b.KV_PERSONNR, row_number() over(order 
    by b.KV_PERSONNR), @lvl 
    FROM PERSONSMANAGER b 
    inner join @foo f on b.KV_MANAGERNR = f.KV_PERSONNR 
    --might be multiple paths to this recursion so eliminate duplicates 
    left join @foo dup on dup.KV_PERSONNR = b.KV_PERSONNR 
    WHERE f.lvl = @lvl-1 and dup.KV_PERSONNR is null 

    set @rows=@@ROWCOUNT 
END 

SELECT DISTINCT KV_PERSONNR from @foo order by KV_PERSONNR

DECLARE 
    v_lvl Number:=0; 
    v_rows number:=1; 
BEGIN 
    INSERT INTO nt_list_0 (KV_MANAGERNR, KV_PERSONNR, ord, lvl) 
     select KV_MANAGERNR, KV_PERSONNR, row_number() over(order by 
     KV_PERSONNR), 0 from PERSONSMANAGER where KV_MANAGERNR='100047'; 

    WHILE v_rows>0 
    LOOP 
     v_lvl := v_lvl +1; 

     INSERT INTO nt_list_0 (KV_MANAGERNR, KV_PERSONNR, ord, lvl) 
     SELECT DISTINCT b.KV_MANAGERNR, b.KV_PERSONNR, row_number() 
      over(order by b.KV_PERSONNR), v_lvl 
     FROM PERSONSMANAGER b 
     inner join nt_list_0 f on b.KV_MANAGERNR = f.KV_PERSONNR 
     left join nt_list_0 dup on dup.KV_PERSONNR = b.KV_PERSONNR 
     WHERE f.lvl = v_lvl-1 and dup.KV_PERSONNR is null; 

     v_rows := sql%rowcount; 
    END LOOP; 
END;
