Say i have the following table, using Oracle 10g
ARTIFACT_LABEL | DEPENDANT_ON
test1 | abc1
test1 | abc2
test1 | abc3
abc3 | xyz1
abc4 | xyz2
并且 i 想要生成一个树木结构,了解
SELECT ARTIFACT_LABEL, DEPENDANT_ON
FROM DEPENDANCIES
START WITH ARTIFACT_LABEL = test1
CONNECT BY NOCYCLE PRIOR ARTIFACT_LABEL = DEPENDANT_ON
但是,这种意向性工作(似乎只是采用<代码>)。 SlectT: ARTIFACT_LABEL = 测试1
Any ideas where im going wrong?
由于你从树木底部开始工作,所以把问题的最后部分改为:
PRIOR DEPENDANT_ON = ARTIFACT_LABEL
