Last Execution Date at source

Question

Hi Guru Sankar
Sometime back i had some requirement to get last update date of target tables .
I had changed the IKM and added the step as per your suggestion
i.e insert into xxsm_audit_table (SESS_NO, SESS_NAME,TARGET_TABLE_NAME, DATE_UPDATED) (SELECT <%=odiRef.getSession("SESS_NO")%>, '<%=odiRef.getSession("SESS_NAME")%>','<%=odiRef.getTargetTable("RES_NAME")%>',sysdate FROM dual)
Now my requirement is similar but this time i want the same at source database and source tables
I am using ODI 10.1.3.5.
I have created a table at source DB.i.e xxsm_odi_audit_table and tried the modified query as below
with the above step but at Command on Source
insert into xxsm_audit_table (SESS_NO, SESS_NAME,TARGET_TABLE_NAME, DATE_UPDATED) (SELECT <%=odiRef.getSession("SESS_NO")%>, '<%=odiRef.getFrom("SESS_NAME")%>','<%=odiRef.getTargetTable("RES_NAME")%>',sysdate FROM dual)
But i am getting error invalid SQL Statement.
My source is having multiple source tables/views/synonyms
can you tell me what i am doing wrong???

Hi Gourisankar,
If u need to capture SOURCE table list then ur customization should be at LKM level not at IKM level. For capturing source table list in spite of multiple tables (views, synonyms, tables etc) u can do it using a API called getSrcTablesList.
Do the following steps.
Step 1:
Create a new step in ur LKM (LKM SQL To SQL) after Load Data Step.
Step Name: Insert Audit Log
Command On Source:
Technology: Oracle
Logical Schema : <whichever schema points to ur xxsm_audit_table table>
Command:
SELECT '<%=odiRef.getSrcTablesList("", "[RES_NAME]", ", ", "")%>' as SrcTable FROM dual
Command On Target:
Technology : Jython
Command:
import java.sql as sql
import java.lang as lang
#Get the log table connection information by using getJDBCConncetion("SRC")
myCon =odiRef.getJDBCConnection("SRC")
MyStmt=myCon.createStatement()
#Assigning Source Table List to a Jython variable
JSrcTable='#SrcTable'
#Insert into xxsm_audit_table with the source table/tables list
LogInsert= MyStmt.executeQuery("insert into xxsm_audit_table (SESS_NO, SESS_NAME,TARGET_TABLE_NAME, DATE_UPDATED) (SELECT <%=odiRef.getSession("SESS_NO")%>, '<%=odiRef.getSession("SESS_NAME")%>','"@JSrcTable@"',sysdate FROM dual)")
P.S: Replace @ with plus sign the above line.
That's it.
Please note, if u have multiple source table used in ur interface then those will be inserted with comma (,) separated in to audit table.
Also, make sure u need to add this in ALL the LKM wherever u require to capture the source table names.
Let me know how it works.
Thanks,
Guru
