That was my understanding of DB.field also. 

 

I haven’t taken the Performance Tuning class. Does the class cover what the 
difference is between TR and DB and when to use either one?

 

DB may be an efficient search but still a search where as TR would not be a 
search, correct? Even searching by the known record number in a really large 
table still could take some time. Multiply that by tens of thousands of records 
in the import scenario and it really starts adding up.

DB.Field has to query the database.  By definition it is the data that's stored 
in the field in the database.
