The SELECT statement is used to insert new records in a table.
It is possible to write the INSERT INTO statement in two ways:
1. Specify both the column names and the values to be inserted:
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. Here, the INSERT INTO syntax would be as follows:
INSERT INTO table_name
VALUES (value1, value2, value3, ...)
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 | Wolski | Zbyszek | ul. Filtrowa 68 | Walla | 01-012 | Poland |
The following SQL statement inserts a new record in the "Customers" table:
INSERT INTO Customers (CustomerName, ContactName, Address, City, PostalCode, Country)
VALUES ('Cardinal', 'Tom B. Erichsen', 'Skagen 21', 'Stavanger', '4006', 'Norway')
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 |
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):
INSERT INTO Customers (CustomerName, City, Country)
VALUES ('Cardinal', 'Stavanger', 'Norway')
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 | null | null | Stavanger | null | Norway |
