# SQL: INSERT
|
|
|
|
|
|
## Adding a record
|
|
|
|
````sql
|
|
INSERT INTO sales
|
|
VALUES (1, 11, '2020-01-01','mhogan');
|
|
````
|
|
|
|
If you intend to miss out a value, you shouldn't leave it blank, you should instead use `NULL` :
|
|
|
|
````sql
|
|
INSERT INTO sales
|
|
VALUES (1, 11, '2020-01-01', NULL);
|
|
````
|

> There is a problem with this format: it only works so long as the order to the values in the `VALUES` clause corresponds to the order of the fields in the tables. To rule out error we should instead specify these fields along with the table name:
|
|
|
|
````sql
|
|
INSERT INTO sales**(employee_id, sale_id, model_id, sale_date)**
|
|
VALUES ('mhogan', 1, 11, '2020-01-01',);
|
