IIRC, your batch will be lots faster in a transaction, and if you do this:
start transaction
insert parent
start batch
insert children
end batch
end transaction
I think you'll be OK.

Hi,
Is it possible to insert data into a parent table and then use the generated
primary key to insert into a child table.
I need to do this during a batch insert as it is necessary(performance).
Thanking you for any lead that may be provided in solving this problem.(I
spent a day , on this problem J)
The sample code below has a comment specifying where the problem is
public void batchInsertTable(
final List beanList) {
getSqlMapClientTemplate().execute(new
SqlMapClientCallback() {
public Object
doInSqlMapClient(SqlMapExecutor executor)
throws
SQLException {
executor.startBatch();
for (int i = 0; i <
beanList.size(); i++) {
Integer
primaryKey = (Integer)executor.insert("populateTable",
beanList.get(i));
//use primaryKey for storing info in child table
//Problem is that in batch insert the primarykey value returned is random
number (not the //one in database)
}
executor.executeBatch();
return null;
}
});
}
