SQL Appending Data

Hi, is the following SQL statement right? It ran but I'm not too sure

INSERT INTO tblIPI ( Datev, Cansim, VariableName,MonthlyValue )
SELECT tbl_Import.Datev, tbl_Import.Cansim, tbl_Import.VariableName, tbl_Import.MonthlyValue
From tbl_Import;

More specifically, the

From tbl_Import;

If you see this davegugg, I am working on another database dump and have struggled with both the Excel code and SQL statements. I guess the real question is, if From absolutely necessary when appending data?
