Informatica存储库：如何获取SQL转换中存储的SQL查询

Question

我想使用INFA repo表获取SQL转换中使用的以下sql查询。在映射中 - > sql transformation - > SQL ports - > SQL查询

Answer 1

您要查找的数据位于表OPB_METAEXT_VAL.PM_VALUE上的OPB_METAEXT_VAL列中

SELECT *
FROM OPB_METAEXT_VAL
WHERE METAEXT_NAME='SQL_Query' 

大型报表可能分布在多行中，因此按OPB_METAEXT_VAL.LINE_NO排序。

您可以加入OPB_SUBJECT上的OPB_SUBJECT.SUBJ_ID = OPB_METAEXT_VAL.SUBJECT_ID获取文件夹名称。您也可以加入OPB_WIDGET_INST上的OPB_WIDGET_INST.WIDGET_ID = OPB_METAEXT_VAL.OBJECT_ID AND OPB_WIDGET_INST.REF_VERSION_NUMBER = OPB_METAEXT_VAL.VERSION_NUMBER以获得有关转型的其他详细信息。

然后，您可以进一步加入其他表，例如，如果您需要文件夹名称，工作流/工作组，会话，映射，转换，SQL和数据库连接，请使用以下内容：

  WITH OPB_SESS_CNX_REFS_WRAPPER AS
(
    SELECT OPB_SESS_CNX_REFS.*,
    rank() over(
           partition BY 
                  WORKFLOW_ID, 
                  SESSION_ID, 
                  SESSION_INST_ID, 
                  PROC_INSTANCE_ID  
           order by 
                  VERSION_NUMBER DESC, 
                  SESS_WIDG_INST_ID ASC 
    ) AS  THE_RANK
    FROM OPB_SESS_CNX_REFS
)
