# SQL INSERT INTO Statement

The INSERT INTO statement is used to insert new records in a table.

## The INSERT INTO Statement

The INSERT INTO statement is used to insert a new row in a table.

### SQL INSERT INTO Syntax

It is possible to write the INSERT INTO statement in two forms.

The first form doesn't specify the column names where the data will be inserted, only their values:

    INSERT INTO table_name
    VALUES (value1, value2, value3,...)

The second form specifies both the column names and the values to be inserted:

    INSERT INTO table_name (column1, column2, column3,...)
    VALUES (value1, value2, value3,...)

## SQL INSERT INTO Example

We have the following "Persons" table:

P_Id | LastName | FirstName | Address | City
--- | --- | --- | --- | ---
1 | Hansen | Ola | Timoteivn 10 | Sandnes
2 | Svendson | Tove | Borgvn 23 | Sandnes
3 | Pettersen | Kari | Storgt 20 | Stavanger

Now we want to insert a new row in the "Persons" table.

We use the following SQL statement:

    INSERT INTO Persons
    VALUES (4,'Nilsen', 'Johan', 'Bakken 2', 'Stavanger')

The "Persons" table will now look like this:

P_Id | LastName | FirstName | Address | City
--- | --- | --- | --- | ---
1 | Hansen | Ola | Timoteivn 10 | Sandnes
2 | Svendson | Tove | Borgvn 23 | Sandnes
3 | Pettersen | Kari | Storgt 20 | Stavanger
4 | Nilsen | Johan | Bakken 2 | Stavanger

## Insert Data Only in Specified Columns

It is also possible to only add data in specific columns.

The following SQL statement will add a new row, but only add data in the "P_Id", "LastName" and the "FirstName" columns:

    INSERT INTO Persons (P_Id, LastName, FirstName)
    VALUES (5, 'Tjessem', 'Jakob')

The "Persons" table will now look like this:

P_Id | LastName | FirstName | Address | City
--- | --- | --- | --- | ---
1 | Hansen | Ola | Timoteivn 10 | Sandnes
2 | Svendson | Tove | Borgvn 23 | Sandnes
3 | Pettersen | Kari | Storgt 20 | Stavanger
4 | Nilsen | Johan | Bakken 2 | Stavanger
5 | Tjessem | Jakob |  |
