Is incremental Load possible without Primary Key? Can I do concatenation without using "Where not exists(primary key)" in qvd load?

Hi,

In my below query, there is no primary key(Sequential ID). Can we implement Incremental Load using some other field which not Primary Key?

Since I do not have primary key, I just want to concatenate the qvd file with new data (no updation and deletion of records) . Can I do concatenation without using "Where not exists(primary key)" in qvd load? Can I go ahead without using "Inner Join" (for deletion of records)?

Please help me.

//Metrics:
//LOAD
// num(replace(left("time_stamp",16),'T',' ')) as MetricTimestampKey,
// num(replace(left("time_stamp",16),'T',' ')) as DTE,
// //Floor(num(QV_TIMESTAMP)) as Date_DTE,
// time_stamp as TIME_STAMP,
// type as MetricType,
// field1 as FIELD1,
// field2 as FIELD2,
// field3 as FIELD3,
// field4 as FIELD4,
// field5 as FIELD5,
// field6 as FIELD6,
// field7 as FIELD7,
// field8 as FIELD8,
// field9 as FIELD9,
// field10 as FIELD10,
// if(type='2' or type='3' or type='4' or type='5' or type='8' or type='9' or type='11' or type='50' or type='51' or type='52', ApplyMap('Network_map',field1,field1), field1) as AllNetworkType,
// if(type='2' or type='4', ApplyMap('Network_status_map',field2,field2),field2) as AllNetworkStatus,
// if(type='4', ApplyMap('Network_status_map',field3,field3),field3) as AllNetworkStatus2,
// if(type='3', ApplyMap('Update_status_map',field2,field2),field2) as AllUpdateStatus,
