Question

我有这个问题：

SELECT PAI, FILHO
FROM
(
  SELECT PAI, FILHO
  FROM
  (
    SELECT 'CT_'||SUBSTR(TRIM(TBP.CTS_ORDEM), -10) PAI, 
           'CT_'||SUBSTR(TRIM(TBC.CTS_ORDEM), -10) FILHO
    FROM PETROSUAPE_P10.CTS010@DBL_DWHYP_TOTVS TBC, 
         PETROSUAPE_P10.CTS010@DBL_DWHYP_TOTVS TBP
    WHERE TBC.CTS_CODPLA = 'AVD' 
      AND TBP.CTS_CODPLA = 'AVD' 
      AND TBC.D_E_L_E_T_ <> '*' 
      AND TBP.D_E_L_E_T_ <> '*' 
      AND TBC.CTS_CTASUP = TBP.CTS_CONTAG

  )
)
START WITH PAI = 'CT_0000000001'
CONNECT BY NOCYCLE PRIOR FILHO = PAI;

那只是回归：

CT_0000000001   CT_0000000011
CT_0000000001   CT_0000000101
CT_0000000001   CT_0000000141

但如果我跑：

SELECT 'CT_'||SUBSTR(TRIM(TBP.CTS_ORDEM), -10) PAI, 
       'CT_'||SUBSTR(TRIM(TBC.CTS_ORDEM), -10) FILHO
    FROM PETROSUAPE_P10.CTS010@DBL_DWHYP_TOTVS TBC, 
         PETROSUAPE_P10.CTS010@DBL_DWHYP_TOTVS TBP
    WHERE TBC.CTS_CODPLA = 'AVD' 
      AND TBP.CTS_CODPLA = 'AVD' 
      AND TBC.D_E_L_E_T_ <> '*' 
      AND TBP.D_E_L_E_T_ <> '*' 
      AND TBC.CTS_CTASUP = TBP.CTS_CONTAG
      AND 'CT_'||SUBSTR(TRIM(TBP.CTS_ORDEM), -10) = 'CT_0000000141'

它让我回来......

CT_0000000141   CT_0000000161
CT_0000000141   CT_0000000191
CT_0000000141   CT_0000000201
CT_0000000141   CT_0000000231
CT_0000000141   CT_0000000151
CT_0000000141   CT_0000000211
CT_0000000141   CT_0000000891
CT_0000000141   CT_0000000261
CT_0000000141   CT_0000000901
CT_0000000141   CT_0000000272
CT_0000000141   CT_0000000273
CT_0000000141   CT_0000000171
CT_0000000141   CT_0000000181
CT_0000000141   CT_0000000221
CT_0000000141   CT_0000000251
CT_0000000141   CT_0000000271
CT_0000000141   CT_0000000274

我需要它让我的成员CT_0000000001及其子女，儿童的孩子，孩子的孩子，等等......

有人可以帮助我发现它为什么不起作用吗？

提前致谢！
