Ignoring errors
Normally INSERT stops and rolls back when it encounters an error.
By using the IGNORE keyword all errors are converted to warnings, which will not stop inserts of additional rows.
Examples
How to specify the column names:
INSERT INTO person (first_name, last_name) VALUES ('John', 'Doe');
How to insert more than 1 row at a time:
INSERT INTO tbl_name VALUES (1, "row 1"), (2, "row 2");
Using the SET clause:
INSERT INTO person SET first_name = 'John', last_name = 'Doe';
SELECTing from another table:
INSERT INTO contractor SELECT * FROM person WHERE status = 'c';
See INSERT ON DUPLICATE KEY UPDATE for further examples using that syntax.
