Assume that column_1 of table_1 is a GENERATED BY DEFAULT identity column.

     INSERT INTO table_2 (column_1, column_2, column_3)
       VALUES (111,111,111);
     INSERT INTO table_2 (column_1, column_2, column_3)
       VALUES (222,222,222);
     INSERT INTO table_2 (column_1, column_2, column_3)
       VALUES (1,333,333);

     INSERT INTO table_1 (column_1, column_2, column_3)
     SELECT * FROM table_2;

Check the result of the insert operations by selecting all the rows from table_1.

     SELECT *
     FROM table_1;

Result:

     *** Query completed. 3rows found. 3 columns returned.
     *** Total elapsed time was 1 second.
