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,
