SQL SELECT INTO Statement

SQL SELECT INTO Statement : SQL SELECT INTO statement copies data from one table into a new table.

SELECT INTO Syntax

Copy all columns into a new table:

SELECT *
INTO newtable [IN externaldb]
FROM oldtable
WHERE condition;

Copy only some columns into a new table:

SELECT column1column2column3, …
INTO newtable [IN externaldb]
FROM oldtable
WHERE condition;

The new table will be created with the column-names and types as defined in the old table. You can create new column names using the AS clause.

 

SQL SELECT INTO Examples

The following SQL statement creates a backup copy of Customers:

SELECT * INTO CustomersBackup2017
FROM Customers;

The following SQL statement uses the IN clause to copy the table into a new table in another database:

SELECT * INTO CustomersBackup2017 IN ‘Backup.mdb’
FROM Customers;

The following SQL statement copies only a few columns into a new table:

SELECT CustomerName, ContactName INTO CustomersBackup2017
FROM Customers;

The following SQL statement copies only the German customers into a new table:

SELECT * INTO CustomersGermany
FROM Customers
WHERE Country = ‘Germany’;

The following SQL statement copies data from more than one table into a new table:

SELECT Customers.CustomerName, Orders.OrderID
INTO CustomersOrderBackup2017
FROM Customers
LEFT JOIN Orders ON Customers.CustomerID = Orders.CustomerID;

Tip:

SELECT INTO can also be used to create a new, empty table using the schema of another. Just add a WHERE clause that causes the query to return no data:

SELECT * INTO newtable
FROM oldtable
WHERE 1 = 0;
