SQL Server 存储过程。 插入表

Question

The problem that I have is that 2 of my parameters that need to add into my table with a stored procedure are values that come from 2 other tables and I need to change these 2 values to the proper ones.

I have tried to search for the problem that I have but with no success.

There are 3 tables involved: Movie , AgeRestriction and Price .

Table Movie

• MovieID , int , PK
• Movie, varchar(50)
• Duration, time(0)
• AgeRestrictionID, int, FK - connected with the ID in the AgeRestriction table
• PriceID, int, FK - connected with the ID in the Price table

Table AgeRestriction :

• AgeRestrictionID , int, PK
• AgeRestriction, int

Table Price :

• PriceID, int, PK
• Price, int

The 2 values that i add is the value ( AgeRestriction, int ) from the AgeRestriction table and ( Price, int ) from the Price table.

This is how I need to insert the values I get into the table Movies .

 public void InsertMovie(Movie movie)
 {
        using (SqlConnection conn = CreateConnection())
        {
            try
            {
                SqlCommand cmd = new SqlCommand("dbo.AddMovie", conn);
                cmd.CommandType = CommandType.StoredProcedure;

                cmd.Parameters.Add("@Movie", SqlDbType.NVarChar, 50).Value = movie._movie;
                cmd.Parameters.Add("@Duration", SqlDbType.Time, 0).Value = movie.Duration;
                cmd.Parameters.Add("@AgeRestriction", SqlDbType.Int, 50).Value = movie.AgeRestriction;
                cmd.Parameters.Add("@Price", SqlDbType.Decimal, 50).Value = movie.Price;

                conn.Open();
                cmd.ExecuteNonQuery();
            }
            catch
            {
                throw new ApplicationException("An error occured in the data access layer.");
            }
        }
    }

So, I'm trying to create a stored procedure that can do all this but so far with no success so I'm asking you guys here..

Answer 1

Okey, this is what ive tried:

ALTER PROCEDURE [dbo].[AddMovie]
@Movie varchar(50),
@Duration time(0),
@AgeRestrictionID int,
@PriceID int,
@AgeRestriction int,
@Price int
AS
BEGIN

SET NOCOUNT ON;

BEGIN TRANSACTION
        INSERT INTO Movie (Movie, Duration, AgeRestrictionID, PriceID)
        VALUES (@Movie, @Duration, @AgeRestrictionID, @PriceID)
        SELECT Movie, Duration, AgeRestriction, Price
        FROM Movie AS M
        INNER JOIN AgeRestriction as Ag ON M.AgeRestrictionID = Ag.AgeRestrictionID
        INNER JOIN Price as P ON M.PriceID = P.PriceID

COMMIT
END
