C＃プログラム内でストアドプロシージャを実行する方法

このストアドプロシージャをC＃プログラムから実行したい。

SqlServerクエリウィンドウに次のストアドプロシージャを記述し、stored1として保存しました。

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

例外が表示されますCannot find the stored procedure dbo.test。パスを提供する必要がありますか？はいの場合、ストアドプロシージャはどの場所に保存する必要がありますか？

C＃でのストアプロシージャの呼び出し

    cmd.CommandType=CommandType.StoredProcedure;
    cmd.Parameters.AddWithValue("@value",txtValue.Text);
    con.Open();
    int rowAffected=cmd.ExecuteNonQuery();

}

これは、リフレクションを介してパラメータを使用して、または使用せずにストアドプロシージャを実行するためのコードです。オブジェクトのプロパティ名は、ストアドプロシージャのパラメータと一致する必要があることに注意してください。

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)
            {
                paramList.Add(new SqlParameter(property.Name, DBNull.Value));
            }
            else
            {
                paramList.Add(new SqlParameter(property.Name, property.GetValue(model)));
            }
        }
        return paramList;

****** Stored Procedure ******

CREATE PROCEDURE Addcontact
@CommandType VARCHAR(MAX) = NULL
AS
BEGIN
  IF (@CommandType = 'GetAllContactType')
  BEGIN

  END
END

これは、値を返し、c＃で実行するストアドプロシージャの例です。

CREATE PROCEDURE [dbo].[InsertPerson]   
-- Add the parameters for the stored procedure here  
@FirstName nvarchar(50),@LastName nvarchar(50),  
@PersonID int output  
AS  
BEGIN  
    insert [dbo].[Person](LastName,FirstName) Values(@LastName,@FirstName)  

    set @PersonID=SCOPE_IDENTITY()  
END  
Go  


--------------
 // Using stored procedure in adapter to insert new rows and update the identity value.  
   static void InsertPersonInAdapter(String connectionString, String firstName, String lastName) {  
      String commandText = "dbo.InsertPerson";  
      using (SqlConnection conn = new SqlConnection(connectionString)) {  
         SqlDataAdapter mySchool = new SqlDataAdapter("Select PersonID,FirstName,LastName from [dbo].[Person]", conn);  

         mySchool.InsertCommand = new SqlCommand(commandText, conn);  
         mySchool.InsertCommand.CommandType = CommandType.StoredProcedure;  

         mySchool.InsertCommand.Parameters.Add(  
             new SqlParameter("@FirstName", SqlDbType.NVarChar, 50, "FirstName"));  
         mySchool.InsertCommand.Parameters.Add(  
             new SqlParameter("@LastName", SqlDbType.NVarChar, 50, "LastName"));  

         SqlParameter personId = mySchool.InsertCommand.Parameters.Add(new SqlParameter("@PersonID", SqlDbType.Int, 0, "PersonID"));  
         personId.Direction = ParameterDirection.Output;  

         DataTable persons = new DataTable();  
         mySchool.Fill(persons);  

         DataRow newPerson = persons.NewRow();  
         newPerson["FirstName"] = firstName;  
         newPerson["LastName"] = lastName;  
         persons.Rows.Add(newPerson);  

         mySchool.Update(persons);  
         Console.WriteLine("Show all persons:");  
         ShowDataTable(persons, 14); 

Dapperの使用。だから私はこれを追加しました。誰かが助けてくれることを願っています。

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();
        }

クレーンをチェックしてください（私は著者です）

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

また、あなたが好きかもしれない他の機能がたくさんあります。

あなたのコードはDDLだということですか？その場合、MSSQLに違いはありません。上記の例は、これを呼び出す方法をよく示しています。確認してください

CommandType = CommandType.Text

ここではDapperの回答はありません。1つ追加しました

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);
