Calling a Stored Procedure From Database Using XI.

Question

Hi,
Please help in writing a UDF for these fields in mapping, which I need for the object Iu2019m doing currently.
The fields are like this:
1) batch_no = "TRUNC((GetMaxObjid('x_txn_sap_parts')-POWER(2,28))/5000)+1",
2) lot_id = "TRUNC((GetMaxObjid('x_txn_sap_parts')-POWER(2,28))/500)+1",
3) How to use JDBC connection factory class in the UDF.
Some logic I can provide which I know i.e. Power (2, 28) means 2 to the power of 28 (2 multiplied 28 times), Trunc means truncate, X_TXN_SAP_Parts is a database table.The Target fields are Batch_no, lot_id & Objid.Actually, objid is mapped initially to a source field i.e. Object ID and in this function it is only being used for the calculation of the batch_no.
I've tried to use this code but still I'm unable to execute the mapping.
import java.util.*;
import com.sap.aii.mapping.lookup.*;
import com.sap.aii.mapping.lookup.*;
DataBaseAccessor accessor = null;
DataBaseResult JDBCOutPayload = null;
String BusinessSystem="clarify_dev_bizsys";
//give your business system having channel name
String CommunicationChannel="JDBC_TO_CDEV";
//give your channel name
String InputPayload= " select X_TXN_PRE_SITE_XFACE.nextval from dual;";
//give your sql query
try {
Channel channel =
LookupService.getChannel(BusinessSystem,CommunicationChannel);
accessor = LookupService.getDataBaseAccessor(channel);
DataBaseResult resultSet = accessor.execute(InputPayload);
for(Iterator rows = resultSet.getRows();rows.hasNext();){
Map rowMap = (Map)rows.next();
Object cValue = rowMap.get("batchno");
//field name of field required , as in database
catch (Exception e) {}
finally {
if (accessor != null)
accessor.close();
result.addValue((String)cValue);
--> I don't know what are the parameters to be used and how to be used in the UDF because this is the first time I'm writing a UDF.
--> The problem in using this query is that both OBJID & BatchNo. are on the target side and the value for the OBJID is retrieved by a SELECT query from the database.
Kindly help me how to resolve this query of mine.
Thanks in Advance.

Hi,
The scenario is like I've to get a field (OBJID) value after using a SELECT statement from the database and use the same value for calculating another field values which is BATCHNO & LOTID.
OBJID, BATCHNO and LOTID are from the same database.
Thats all I was provided as the input.
Do let me know if you need anymore information. I'll try to give as much input to the extent I know.
