Before You Begin

Limitations and Restrictions

When you copy a column that has an alias data type from one database to another, the alias data type may not be available in the destination database. In such a case, the column will be assigned the nearest matching base data type available in that database.

Security

Permissions

Requires ALTER permission on the table.

Using SQL Server Management Studio

To copy column definitions from one table to another

  1. Open the table with columns you want to copy and the one you want to copy into by right-clicking the tables, and then clicking Design.

  2. Click the tab for the table with the columns you want to copy and select those columns.

  3. From the Edit menu, click Copy.

  4. Click the tab for the table into which you want to copy the columns.

  5. Select the column you want to follow the inserted columns and, from the Edit menu, click Paste.

To copy data from one table to another

  1. Follow the directions for copying column definitions above.

    Note

    Before you begin to copy data from one table to another, make sure that the data types in the destination columns are compatible with the data types of the source columns

  2. Open a new Query Editor window.

  3. Right-click the Query Editor, and then click Design Query in Editor.

  4. In the Add Table dialog box, select the source and destination table, click Add, and then close the Add Table dialog box.

  5. Right-click an open area of the Query Editor, point to Change Type, and then click Insert Results.

  6. In the Choose Target Table for Insert Results dialog box, select the destination table.

  7. In the upper portion of the Query Designer, click the source column in the source table.

  8. The Query Designer has now created an INSERT query. Click OK to place the query into the original Query Editor window.

  9. Execute the query to insert the data from the source table to the destination table.

Using Transact-SQL

To copy column definitions from one table to another

  1. You cannot copy individual columns from one table to another existing table by using Transact-SQL statements. However, you can create a new table in the default filegroup and inserts the resulting rows from the query into it by using SELECT INTO. For more information, see INTO Clause (Transact-SQL).

To copy data from one table to another

  1. In Object Explorer, connect to an instance of Database Engine.

  2. On the Standard bar, click New Query.

  3. Copy and paste the following example into the query window and click Execute.

    USE AdventureWorks2022;  
GO  
CREATE TABLE dbo.EmployeeSales  
( BusinessEntityID   varchar(11) NOT NULL,  
  SalesYTD money NOT NULL  
);  
GO  
INSERT INTO dbo.EmployeeSales  
    SELECT BusinessEntityID, SalesYTD   
    FROM Sales.SalesPerson;  
GO
