Inserting Rows by Using INSERT and SELECT Subqueries

The SELECT subquery in the INSERT statement can be used to add values into a table from one or more other tables or views. Using a SELECT subquery also lets more than one row be inserted at the same time.

In the following example the INSERT statement inserts into a separate table some of the data from all the rows in the Sales.SalesReason table in AdventureWorks2008R2 whose SalesReason is Marketing.

USE AdventureWorks2008R2;
GO
CREATE TABLE MySalesReason (
    SalesReasonID int NOT NULL,
    Name nvarchar(50),
    ModifiedDate datetime);
GO
INSERT INTO MySalesReason
    SELECT SalesReasonID, Name, ModifiedDate
    FROM AdventureWorks2008R2.Sales.SalesReason
    WHERE ReasonType = N'Marketing';
GO
SELECT SalesReasonID, Name, ModifiedDate 
FROM MySalesReason;
GO


The select list of the subquery must match the column list of the INSERT statement. If no column list is specified, the select list must match the columns in the table or view being inserted into.

Another use of the INSERT...SELECT statement is to insert data from a source outside SQL Server. The SELECT in the INSERT statement can be used for the following:
