C # 프로그램에서 저장 프로 시저를 실행하는 방법

이 저장 프로 시저를 C # 프로그램에서 실행하고 싶습니다.

SqlServer 쿼리 창에 다음 저장 프로 시저를 작성하고 stored1으로 저장했습니다.

use master
go
create procedure dbo.test as

DECLARE @command as varchar(1000), @i int
SET @i = 0
WHILE @i < 5
BEGIN
Print 'I VALUE ' +CONVERT(varchar(20),@i)
EXEC(@command)
SET @i = @i + 1
END

using (var conn = new SqlConnection(connectionString))
using (var command = new SqlCommand("ProcedureName", conn) {
                           CommandType = CommandType.StoredProcedure }) {
   conn.Open();
   command.ExecuteNonQuery();
}

답변

using (SqlConnection conn = new SqlConnection("Server=(local);DataBase=Northwind;Integrated Security=SSPI")) {
    conn.Open();

    // 1.  create a command object identifying the stored procedure
    SqlCommand cmd  = new SqlCommand("CustOrderHist", conn);

    // 2. set the command object so it knows to execute a stored procedure
    cmd.CommandType = CommandType.StoredProcedure;

    // 3. add parameter to command, which will be passed to the stored procedure
    cmd.Parameters.Add(new SqlParameter("@CustomerID", custId));

    // execute the command
    using (SqlDataReader rdr = cmd.ExecuteReader()) {
        // iterate through results, printing each to console
        while (rdr.Read())
        {
            Console.WriteLine("Product: {0,-35} Total: {1,2}",rdr["ProductName"],rdr["Total"]);
        }
    }

리플렉션을 통해 매개 변수를 사용하거나 사용하지 않고 저장 프로 시저를 실행하기위한 코드입니다. 오브젝트 특성 이름은 스토어드 프로 시저의 매개 변수와 일치해야합니다.
