ODI 10g delete conditional row Using KM

Question

Hi I will add new step to ODI 10g IKM control append
I want to delete from target some columns where is being on source.I will capture updating or new rows then I will delete this rows from target according to UK of Target end of this I will insert.I wrote new step like this:I selected UK rows on target
delete from <%=odiRef.getTable("L","TARG_NAME","A")%> T WHERE (<%=odiRef.getTargetColList("", "[COL_NAME]", ", ", "\n", "UK")%> )
IN
SELECT ---Which method can ı use here?
FROM <%=odiRef.getFrom()%>
WHERE (1=1) AND
<%=snpRef.getJoin()%>
<%=snpRef.getFilter()%>
<%=snpRef.getJrnFilter()%>
<%=snpRef.getGrpBy()%>
<%=snpRef.getHaving()%>
/*commit*/
I have two source S1 and S2
For example my target table is like this:
Target
Asset_id(UK)---it comes from source table. S1.ROW_ID--->T.ASSET_ID
root_asset_id(UK)it comes from source table of S2.PROD_ID-->T.ROOt_ASSET_ID
cre_dt(NOT UK)
etc
Now I want to compare like this :
Delete from target T where (T.ASSET_ID,T.ROOT_ASSET _ID) IN
(SELECT S1.ROW_ID,S2.PROD_ID
FROM SOURCE S1 SOURCE S2)
How can I modify ?
Could anyone help me?
Best Regards,
Thanks

Answer 1

Tell me if I'm wrong : you want to delete in Target the data that are in source.
And insert only source records that were not in your target.
And keep in target data that are not in source.
If so, you can do it like this :
1) Use a copy of "IKM incremental update".
Edit the step "flag row for update"
Rename it to "flag row for delete"
update     <%=snpRef.getTable("L", "INT_NAME", "W")%>
set     IND_UPDATE = 'D'
where     (<%=snpRef.getColList("","[COL_NAME]", ", ", "", "(UK)")%>)
     in (
     select     <%=snpRef.getColList("","[COL_NAME]", ", ", "", "(UK)")%>
     from     <%=snpRef.getTable("L", "TARG_NAME", "A")%>
==> each row of your I$ table that ARE in your target table are now flagged as "D" for "deleted".
it means that each row of your target table that are in source will be flagged as D in your I$ table.
2) Then create a new step "delete row in target" like this :
delete from <%=snpRef.getTable("L","TARG_NAME","A")%> T
where (<%=snpRef.getColList("", "\tT.[COL_NAME]", ",", "", "UK")%>) IN      
(     select <%=snpRef.getColList("", "\t\tS.[COL_NAME]", ",\n", "", "UK")%>
     from <%=snpRef.getTable("L", "INT_NAME", "W")%> S
     where IND_UPDATE = 'D'
==> each row flagged as D will be deleted in the target table
