Major difference between SQL override and Lookup Sql override
Answer / ysindhureddy77@gmail.com
1. SQL Override is to limit the number of incoming rows entering the mapping pipeline
Lookup Override is to limit the number of lookup rows to avoid the whole table scan by saving the lookup time & cache it uses.
2. Lookup Override uses "Order By" clause by default
SQL Override doesn't uses it & should provide in our query if we require it.
3. SQL Override can provide any kind of join by writing the query
Lookup Override provides only Non-Equi joins
4. Lookup Override gives only one record even if it finds multiple records for a single condition
SQL Override doesn’t do that.

For stage table data processing, suppose in first run we processed 8 records out of 10 records then in 2nd run we should consider only not processed records (here total no of records =2) along with new records which got loaded in stage table thru real time mapping. Note : In this example, 8 records are those records for which we got transaction number after lookup on trn_no_cod table and 2 records for which lookup returns trn_no as NULL
