Як виконати збережену процедуру в програмі C #

Я хочу виконати цю збережену процедуру з програми C #.

Я записав таку збережену процедуру у вікно запиту SqlServer і зберег її як збережену1:

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

ВІДМОВЛЕНО:

            Console.WriteLine("\nTop 10 Most Expensive Products:\n");

            try

Це відображає виняток Cannot find the stored procedure dbo.test. Чи потрібно надати шлях? Якщо так, то в якому місці слід зберігати збережені процедури?

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

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"]);
        }

Це код для виконання збережених процедур з і без параметрів за допомогою відображення. Зверніть увагу, що назви властивостей об'єктів повинні відповідати параметрам збереженої процедури.

private static string ConnString = ConfigurationManager.ConnectionStrings["SqlConnection"].ConnectionString;
    private SqlConnection Conn = new SqlConnection(ConnString);

    public void ExecuteStoredProcedure(string procedureName)
    {
        SqlConnection sqlConnObj = new SqlConnection(ConnString);

        SqlCommand sqlCmd = new SqlCommand(procedureName, sqlConnObj);
        sqlCmd.CommandType = CommandType.StoredProcedure;

        sqlConnObj.Open();
        sqlCmd.ExecuteNonQuery();
        sqlConnObj.Close();
    }

    public void ExecuteStoredProcedure(string procedureName, object model)
    {
        var parameters = GenerateSQLParameters(model);
        SqlConnection sqlConnObj = new SqlConnection(ConnString);

        SqlCommand sqlCmd = new SqlCommand(procedureName, sqlConnObj);
        sqlCmd.CommandType = CommandType.StoredProcedure;

        foreach (var param in parameters)
        {
            sqlCmd.Parameters.Add(param);
        }

        sqlConnObj.Open();
        sqlCmd.ExecuteNonQuery();
        sqlConnObj.Close();
    }

    private List<SqlParameter> GenerateSQLParameters(object model)
    {
        var paramList = new List<SqlParameter>();
        Type modelType = model.GetType();
        var properties = modelType.GetProperties();
        foreach (var property in properties)
        {
            if (property.GetValue(model) == null)
            {

Використання Dapper. тому я додав це, я сподіваюся, що хтось допоможе.

public void Insert(ProductName obj)
        {
            SqlConnection connection = new SqlConnection(Connection.GetConnectionString());
            connection.Open();
            connection.Execute("ProductName_sp", new
            { @Name = obj.Name, @Code = obj.Code, @CategoryId = obj.CategoryId, @CompanyId = obj.CompanyId, @ReorderLebel = obj.ReorderLebel, @logo = obj.logo,@Status=obj.Status, @ProductPrice = obj.ProductPrice,
                @SellingPrice = obj.SellingPrice, @VatPercent = obj.VatPercent, @Description=obj.Description, @ColourId = obj.ColourId, @SizeId = obj.SizeId,
                @BrandId = obj.BrandId, @DisCountPercent = obj.DisCountPercent, @CreateById =obj.CreateById, @StatementType = "Create" }, commandType: CommandType.StoredProcedure);
            connection.Close();

SqlServerAccess sqlAccess = new SqlServerAccess("your connection string");
var result = sqlAccess.Command().ExecuteNonQuery("StoredProcedureName");

Також є купа інших функцій, які вам можуть сподобатися.

Ви маєте на увазі, що ваш код DDL? Якщо так, MSSQL не має різниці. Наведені вище приклади добре показують, як викликати це. Просто переконайтесь

CommandType = CommandType.Text

Тут немає відповіді " Dapper" . Тому я додав один

using Dapper;
using System.Data.SqlClient;

using (var cn = new SqlConnection(@"Server=(local);DataBase=master;Integrated Security=SSPI"))
    cn.Execute("dbo.test", commandType: CommandType.StoredProcedure);
