How to read I$ table using ODI procedure

Question

Hi
Can any one help me how to drop a I$ table from out sie of interface.
I have tried below approches but no luck
I have created ODI procedure with technology oracle and target logical schema (I$ tables are creating on target DB) with and with out begin and end;
Approch 1:
Given below code in ODi procedure
drop table <%=odiRef.getTable("L", "INT_NAME", "W")%> <% if (new Integer(odiRef.getOption( "COMPATIBLE" )).intValue() >= 10 ) { out.print( "purge" ); }; %>
Approch 2:
drop table I$_<%=odiRef.getTable("L", "TARG_NAME", "A") %>;
Approch 3:
drop table <%=odiRef.getTable("L", "INT_NAME", "W")%> (but it is fetching target dtabase schema anme not I$ table)
Please help me any other alternative way to drop a I$ table, more over this code should be unique for all interface
Regards,
Phanikanth

Thanks bhabani,
Actaul my requirement is some time my scenario is stoping due some issue at Merge Rows Step (I am using IKM Oracle Incremental Update(Merge) KM) when the next iteration starts it is thwoing and error at create flow table I$ step and error is table name is already exists, so i am doing is if the interface went failed I am storing those information in one table using ODI procedure (INF--ko-->ODI procedure) in same ODI procedure I want to call a I$ table to drop.
Can you please provide the steps so it will very useful for me using Java variable.
I have gievn a step as below on create I$ table step (after create I$ statement)
<@ java.lang.String Idollertable = <%=odiRef.getTable("L", "INT_NAME", "W")%> ; @>
I am calling Idollertable variable in ODI procedure which is ko>* of INF as <@=Idollertable@>
Note: I have followed below approch
ODI Procedure Code:
drop table <@=Idollertable@>; --> *2nd approch*
begin
insert into ODI_EXECUTION_ERROR_DETAILS
(SESSION_NO,
SCENARIO_NAME,
CONTEXT_NAME,
ERR_MESSAGE,
INSERT_COUNT,
ERROR_COUNT)
values
<%=snpRef.getSession("SESS_NO")%>,
'<%=odiRef.getPrevStepLog("STEP_NAME")%>',
'<%=odiRef.getContext( "CTX_NAME" )%>',
'<%=odiRef.getPrevStepLog("MESSAGE")%>',
'<%=odiRef.getPrevStepLog("INSERT_COUNT")%>',
'<%=odiRef.getPrevStepLog("ERROR_COUNT")%>'
commit;
drop table <@=Idollertable@>; --> * first approch *
end;
Please help me
