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:
Reference a remote table on a linked server by using a four-part name. For more information, Identifying a Data Source by Using a Linked Server Name.
Reference a remote table using OPENROWSET. For more information, see Identifying a Data Source by Using an Ad Hoc Name.
Use the result set of a query executed on a remote server. For more information, see Using Pass-Through Queries As Tables.
