Wie können Arrays mithilfe von Tabellenwertparametern (TVPs) effizient an gespeicherte Prozeduren übergeben werden?

<code class="language-sql">CREATE TYPE T1Ids AS Table (
    t1Id INT
);

CREATE PROCEDURE dbo.FindMatchingRowsInTable1 (@Table1Ids AS T1Ids READONLY)
AS
BEGIN
    SET NOCOUNT ON;

    SELECT Table1.t1Id 
    FROM dbo.Table1 AS Table1
    JOIN @Table1Ids AS paramTable1Ids ON Table1.t1Id = paramTable1Ids.t1Id;
END</code>

<code class="language-csharp">DataTable t1Ids = new DataTable();
t1Ids.Columns.Add("t1Id", typeof(int));

int[] listOfIdsToFind = new[] { 1, 5, 9 };
foreach (int id in listOfIdsToFind)
{
    t1Ids.Rows.Add(id);
}

SqlConnection testbedConnection = new SqlConnection(
    @"Data Source=.\SQLExpress;Initial Catalog=TestbedDb;Persist Security Info=True;User ID=testbedUser;Password=letmein12;Connect Timeout=5");

SqlCommand findMatchingRowsInTable1 = new SqlCommand("dbo.FindMatchingRowsInTable1", testbedConnection);
findMatchingRowsInTable1.CommandType = CommandType.StoredProcedure;

SqlParameter sqlParameter = new SqlParameter("Table1Ids", t1Ids);
findMatchingRowsInTable1.Parameters.Add(sqlParameter);</code>

<code class="language-csharp">SqlDataReader sqlDataReader = findMatchingRowsInTable1.ExecuteReader();

while (sqlDataReader.Read())
{
    Console.WriteLine("Matching t1ID: {0}", sqlDataReader["t1Id"]);
}</code>
