Solution 1

You have to define the list of columns to copy between tables.

SQL

INSERT INTO DestinationTable (<ListOfColumns>)
SELECT <ListOfColumns>
FROM SourceTable

For further information, please see: 13.2.5.1 INSERT ... SELECT Syntax[^]

Solution 2

give column names as below

SQL

INSERT INTO ems_db1.drtu_d1 (col1, col2, ..., coln)
SELECT col1, col2, ..., coln
FROM ems_db_to_drtu_d10 
WHERE Device_ID='DRTU_D10';
