## SQL INSERT INTO Statement
The INSERT INTO statement is used to insert new records in a table.
## INSERT INTO Syntax
It is possible to write the INSERT INTO statement in two ways.
1. Specify both the column names and the values to be inserted:
```sql
INSERT INTO table_name (column1, column2, column3, ...)
VALUES (value1, value2, value3, ...);
```
2. If you are adding values for all the columns of the table, you do not need to specify the column names in the SQL query. However, make sure the order of the values is in the same order as the columns in the table. The INSERT INTO syntax would be as follows:
```sql
INSERT INTO table_name
VALUES (value1, value2, value3, ...);
```
## Demo Database
Below is a selection from the "Websites" table:
```
+----+--------------+---------------------------+-------+---------+
| id | name | url | alexa | country |
+----+--------------+---------------------------+-------+---------+
| 1 | Google | https://www.google.cm/ | 1 | USA |
| 2 | Youtube | https://www.youtube.com/ | 2 | USA |
| 3 | | | 3 | CN |
| 4 | Taobao | https://www.taobao.com/ | 13 | CN |
| 5 | Twitter | https://twitter.com/ | 3 | USA |
+----+--------------+---------------------------+-------+---------+
```
## INSERT INTO Example
The following SQL statement inserts a new record in the "Websites" table:
## Example
```sql
INSERT INTO Websites (name, url, alexa, country)
VALUES ('', '', 3, 'CN');
```
(
The following SQL statement will only insert data in the "name", "url", and "country" columns of the "Websites" table:
## Example
```sql
INSERT INTO Websites (name, url, country)
VALUES ('Stackoverflow', 'https://stackoverflow.com/', 'USA');
```
(
## Insert Data in Specified Columns
The following SQL statement will insert a new record, but only insert data in the "name", "url", and "country" columns (id will be updated automatically):
## Example
```sql
INSERT INTO Websites (name, url, country)
VALUES ('Youtube', 'https://www.youtube.com/', 'USA');
```
(
## Insert Multiple Rows
The following SQL statement inserts three new records in the "Websites" table:
## Example
```sql
INSERT INTO Websites (name, url, alexa, country)
VALUES
('Taobao', 'https://www.taobao.com/', 13, 'CN'),
('QQ', 'https://www.qq.com/', 9, 'CN'),
('Facebook', 'https://www.facebook.com/', 3, 'USA');
```

The following is the selection from the "Websites" table after the insertion:
```
