To insert records into a table using SQL:
INSERT INTO table_name (column_1, column_2, column_3,...)
VALUES
('value_1', 'value_2', 'value_3', ...)
The Example
Assume that you created an empty table called the ‘product‘ table which contains 3 columns: product_id, product_name, and price:
CREATE TABLE product (
product_id int primary key,
product_name nvarchar(50),
price int
)
The ultimate goal is to insert the following 4 records into the table:
| product_id | product_name | price |
| 1 | Computer | 800 |
| 2 | TV | 1200 |
| 3 | Printer | 150 |
| 4 | Desk | 400 |
Insert Records Into the Table using SQL
The query below can be used to insert the 4 records into the ‘product‘ table:
INSERT INTO product (product_id, product_name, price)
VALUES
(1,'Computer',800),
(2,'TV',1200),
(3,'Printer',150),
(4,'Desk',400)
After running the above query, the 4 records will be inserted into the ‘product‘ table.
To verify that the records were added to the table, run the following SELECT query:
SELECT * FROM product
You’ll now see the newly inserted records:
| product_id | product_name | price |
| 1 | Computer | 800 |
| 2 | TV | 1200 |
| 3 | Printer | 150 |
| 4 | Desk | 400 |
Insert Additional Records to the Table
You can insert additional records to the table at anytime using the same technique as reviewed above.
For example, here is a query to insert two additional records into the ‘product‘ table:
INSERT INTO product (product_id, product_name, price)
VALUES
(5,'Chair',120),
(6,'Tablet',300)
After running the query, the two additional records will be inserted into the table.
Rerun the SELECT query:
SELECT * FROM product
You’ll see that the two additional records were indeed inserted at the bottom of the table:
| product_id | product_name | price |
| 1 | Computer | 800 |
| 2 | TV | 1200 |
| 3 | Printer | 150 |
| 4 | Desk | 400 |
| 5 | Chair | 120 |
| 6 | Tablet | 300 |
