how to insert data into table using select query Oracle code example

Example 1: oracle insert from select

INSERT INTO my_table SELECT * FROM source_table;
INSERT INTO my_table (a, b, c) SELECT a, b, c FROM source_table;
INSERT INTO my_table (a, b, c) SELECT a, b, c FROM source_table s
	WHERE s.my_col > sysdate;
