        SQL INSERT INTO Statement


        The 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.

        The first way specifies both the column names and the values to be inserted:

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

        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:

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

        Demo Database

        Below is a selection from the "Customers" table in the Northwind sample database:

        CustomerID CustomerName ContactName Address City PostalCode Country
        89 White Clover Markets Karl Jablonski 305 - 14th Ave. S. Suite 3B Seattle 98128 USA
        90

        Wilman Kala Matti Karttunen Keskuskatu 45 Helsinki 21240 Finland
        91

        INSERT INTO Example

        The following SQL statement inserts a new record in the "Customers" table:

        Example

        INSERT INTO Customers (CustomerName, ContactName, Address, City, PostalCode, Country)
        VALUES ('Cardinal', 'Tom B. Erichsen', 'Skagen 21', 'Stavanger', '4006', 'Norway');
        Try it Yourself »

        The selection from the "Customers" table will now look like this:

        CustomerID CustomerName ContactName Address City PostalCode Country
        89 White Clover Markets Karl Jablonski 305 - 14th Ave. S. Suite 3B Seattle 98128 USA
        90

        Wilman Kala Matti Karttunen Keskuskatu 45 Helsinki 21240 Finland
        91

        Wolski Zbyszek ul. Filtrowa 68 Walla 01-012 Poland
        92 Cardinal Tom B. Erichsen Skagen 21 Stavanger 4006 Norway

        Did you notice that we did not insert any number into the CustomerID field?
        The CustomerID column is an auto-increment field and will be generated automatically when a new record is inserted into the table.


        Insert Data Only in Specified Columns

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

        The following SQL statement will insert a new record, but only insert data in the "CustomerName", "City", and "Country" columns (CustomerID will be updated automatically):

        Example

        INSERT INTO Customers (CustomerName, City, Country)
        VALUES ('Cardinal', 'Stavanger', 'Norway');
        Try it Yourself »

        The selection from the "Customers" table will now look like this:

        CustomerID CustomerName ContactName Address City PostalCode Country
        89 White Clover Markets Karl Jablonski 305 - 14th Ave. S. Suite 3B Seattle 98128 USA
