Pass a table variable to stored procedure?

Question

I have this table

CREATE TABLE [dbo].[Sale]
(
    [SaleId] [int] IDENTITY(1,1) PRIMARY KEY,
    [SaleDate] [datetime] NOT NULL DEFAULT GETDATE(),
    [UserPhone] char(10) NOT NULL,
    [NumberSale] [int] NOT NULL,
)

Then I have this table variable

DECLARE @sale1 TABLE  
               (
                   Phone char(10), 
                   GoodId int, 
                   GoodCount int
               )

INSERT INTO @sale1 
VALUES ('0671112221', 1, 2),
       ('0671112221', 4, 1),
       ('0671112221', 13, 2);

I am creating a stored procedure to input data into the table using table variable. But table is underlined.

CREATE PROCEDURE spSalesAndSalesPosInsert
    @data table -- here is  a mistake 
AS
BEGIN
    BEGIN TRY
        BEGIN TRANSACTION;
            
        INSERT INTO Sale (UserPhone, NumberSale)
            SELECT Phone, GoodCount 
            FROM @data
        
        COMMIT TRANSACTION;
    END TRY
    BEGIN CATCH
        ROLLBACK TRANSACTION;       
    END CATCH;
END;

What am I doing wrong?

Answer 1

The table keyword is reserved for other scenarios than passing a parameter.

Have look a this example from the documentation that passes a table-valued parameter to a stored procedure by creating a user-defined type .

Answer 2

You need to declare a user-defined type for the table.

CREATE TYPE myTableType AS TABLE
(
    Phone char(10), GoodId int, GoodCount int
)

Then you can use it:

declare @sale1 myTableType
insert into @sale1 
values
('0671112221', 1, 2),
('0671112221', 4, 1),
('0671112221', 13, 2);

create proc spSalesAndSalesPosInsert
@data myTableType
as
begin
    --Etc....
