You can use
insert into tbl_test1 (col1,col2,col3)
(select col_1,col_2,col_3 from tbl_test)
OR
insert into tbl_test1 select col1,col2,col3 from tbl_test
(here is one condition that Columns has to be same as tbl_test)
But, If you want to insert only one row then,
you can apply condition to select query.
