This should be a fairly straightforward question, but I haven\'t been able to find a solid answer online. I\'m trying to insert multiple rows into the same table, but with o

    As others have said, the key here is UNION ALL. For me, using a CTE keeps things looking a little cleaner e.g.

    WITH NewStuff (Name, Location)
         AS
         (
          SELECT 'Name1', 'Location1' UNION ALL
          SELECT 'Name2', 'Location2' UNION ALL
          SELECT 'Name3', 'Location3' 
         )
    INSERT INTO Stuff (Name, Location) 
    SELECT Name, Location
      FROM NewStuff;

    Yep. You have to use UNION ALLs in SQL Server 2005 to insert multiple rows in a SQL script in a single statement.

    INSERT INTO Table 
      (Name, Location) 
    SELECT 'Name1', 'Location1' 
    UNION ALL
    SELECT 'Name2', 'Location2'
    UNION ALL
    SELECT 'Name3', 'Location3' 
    

    The other main alternative is to repeat the Insert statement multiple times which is even more verbose. You need to be careful to use Explicit transactions in this last case to avoid the overhead of many individual commits (and for atomicity reasons of course)

    If you have lots of rows to insert you could use BULK INSERT to load it all in from a delimited file in one statement.

    Finally if this is data already in the database that you are scripting out (perhaps to deploy on another server) the SSMS Tools Pack addin has a "Generate Insert Statements" function that can generate these statements for you.

    You have to use the union all in sql server 2005. To be honest, that's so clunky and ugly, I'd just use multiple inserts if I were you. Wrap them in a single transaction and it's the same thing in the end.

    Yes they are your only options, unless you are inserting a lot of data and might want to explore a BULK INSERT

    INSERT INTO Table (Name, Location)
    SELECT 'Name1', 'Location1' UNION ALL
    SELECT 'Name2', 'Location2' UNION ALL
    SELECT 'Name3', 'Location3'

    Since MS SQLServer 2005 supports XML the best method I would suggest is a STORED PROCEDURE with an input parameter of XML type. If you are working with .NET you can easily convert the DataSet to xml string using ds.GetXml() method and can be sent to the SP

    CREATE PROCEDURE [dbo].[insertLocation](@XML XML=NULL)
    AS
    BEGIN
      INSERT INTO [dbo].[TheLocations]
            ( [Name], [Location] )
       SELECT
            XTab.value('Name[1]','nvarchar(100)') AS[Name],
            XTab.value('Location[1]','nvarchar(200)') AS[Location]
        FROM @XML.nodes('TheLocations') XTab([XTab])
    END
