# Table Valued Parameters

# Using a table valued parameter to insert multiple rows to a table

First, define a used defined table type (opens new window) to use:

CREATE TYPE names as TABLE
(
    FirstName varchar(10),
    LastName varchar(10)
)
GO

Create the stored procedure:

CREATE PROCEDURE prInsertNames
(
    @Names dbo.Names READONLY -- Note: You must specify the READONLY
)
AS

INSERT INTO dbo.TblNames (FirstName, LastName)
SELECT FirstName, LastName
FROM @Names 
GO

Executing the stored procedure:

DECLARE @names dbo.Names
INSERT INTO @Names VALUES
('Zohar', 'Peled'),
('First', 'Last')

EXEC dbo.prInsertNames @Names

# Remarks

Table valued parameters (TVP for short) are parameters passed to a stored procedure or function that contains data that is table structured. Using table valued parameters requires creating a user defined table type (opens new window) for the parameter being used.

Tabled valued parameters are readonly parameters.
