Insert data into table

In my previous post, I explained how to create a table. In this post, I am going to show how to insert data into table employee.


Following is my employee table structure.
mysql> describe employee;
+-------+-------------+------+-----+---------+-------+
| Field | Type        | Null | Key | Default | Extra |
+-------+-------------+------+-----+---------+-------+
| id    | int(11)     | YES  |     | NULL    |       |
| name  | varchar(20) | YES  |     | NULL    |       |
+-------+-------------+------+-----+---------+-------+
2 rows in set (0.00 sec)

By using INSERT INTO statement, you can insert records into a table.


mysql> INSERT INTO employee VALUES (1, "Hari Krishna");
Query OK, 1 row affected (0.00 sec)

mysql> INSERT INTO employee VALUES (2, "Gopi");
Query OK, 1 row affected (0.00 sec)

You can also specify the fields order, while inserting.


mysql> INSERT INTO employee (name, id) VALUES ("Sudhir", 3);
Query OK, 1 row affected (0.00 sec)

mysql> SELECT * FROM employee;
+------+--------------+
| id   | name         |
+------+--------------+
|    1 | Hari Krishna |
|    2 | Gopi         |
|    3 | Sudhir       |
+------+--------------+
3 rows in set (0.00 sec)
