Create UNION queries (Visual Database Tools)

Applies to: SQL Server

The UNION keyword enables you to include the results of two SELECT statements in one resulting table. All rows returned from either SELECT statement are combined into the result of the UNION expression. For examples, see SELECT examples.

Note

The Diagram pane can only display one SELECT clause. Therefore, when you're working with a UNION query, Query Designer hides the Table Operations pane.

Create a merged SELECT query

  1. Open a query or create a new one.

  2. In the SQL pane, type a valid UNION expression.

    The following example is a valid UNION expression.

    SELECT ProductModelID,
       Name
FROM Production.ProductModel
UNION
SELECT ProductModelID,
       Name
FROM dbo.Gloves;

  3. On the Query Designer menu, select Execute SQL to run the query.

    Your UNION query is now formatted by Query Designer.
