c# - 如何使用 Castle ActiveRecord 执行存储过程？

Question

我相信网上某处有关于这个话题的讨论，但我丢失了网址，我无法通过谷歌搜索找到它。

我现在可能会尝试的是：

ISessionFactoryHolder factoryHolder = ActiveRecordMediator<EntityClass>.GetSessionFactoryHolder();
ISession session = factoryHolder.CreateSession(typeof(EntityClass));
try
{
    IDbCommand cmd = session.Connection.CreateCommand();
    cmd.CommandText = "spName";
    cmd.ExecuteNonQuery();
}
catch(Exception ex)
{

}
finally
{
    factoryHolder.ReleaseSession(session);
}

但是，我不太确定这是否是正确的方法，或者是否存在更好的方法。

Answer 1

这对我有用（带有参数和动态结果表的存储过程）：

// get Connection
System.Data.IDbConnection con = ActiveRecordMediator.GetSessionFactoryHolder()
                                                    .GetSessionFactory(typeof(Autocomplete))
                                                    .ConnectionProvider.GetConnection();

// set Command
System.Data.IDbCommand cmd = con.CreateCommand();
cmd.CommandText = "name_of_stored_procedure";
cmd.CommandType = System.Data.CommandType.StoredProcedure;

// set Parameter of Stored Procedure
System.Data.SqlClient.SqlParameter param = new System.Data.SqlClient.SqlParameter("@parameter_name", System.Data.SqlDbType.NVarChar);
param.Value = "value_of_parameter";
((System.Data.SqlClient.SqlParameterCollection)cmd.Parameters).Add(param);

// call Stored Procedure (without getting result)
cmd.ExecuteNonQuery();

// ... or read results
System.Data.SqlClient.SqlDataReader r = (System.Data.SqlClientSqlDataReader)cmd.ExecuteReader();
while(r.Read()) {
    System.Console.WriteLine("result first col: " + r.GetString(0));
}

我在 ActiveRecord 代码中实现存储过程时使用的博客是 Rodj 的这篇文章（http://blog.rodj.org/archive/2008/05/23/activerecord-nhibernate-and-sql-stored-procedures.aspx） . 使用他的帖子和评论，我能够做到这一点。我还没有决定这是否是最好的方法。

您还可以通过以下方式获得 IDbConnection：

ActiveRecordMediator.GetSessionFactoryHolder()
    .GetSessionFactory(typeof(ActiveRecordBase))
    .ConnectionProvider.GetConnection();

Answer 4

对于 ActiveRecord 版本 1，这有效：

IDbConnection connection = ActiveRecordMediator.GetSessionFactoryHolder()
                          .GetSessionFactory(typeof(ActiveRecordBase))
                          .OpenSession().Connection;

public ArrayList DevolverCamposDeObjetoSTP(T Objeto, List<Consulta> Consultas, string StoredProcedureName)
    {
        ArrayList results;
        try
        {
            var queryString = @"EXEC " + StoredProcedureName;
            foreach (var consulta in Consultas)
            {
                switch (consulta.tipoCampo)
                {
                    case Consulta.TipoCampo.dato:
                        queryString = queryString + " " + consulta.Campo + " = " + "'" + consulta.Valor + "'";
                        break;
                    case Consulta.TipoCampo.numero:
                        queryString = queryString + " " + consulta.Campo + " = " + consulta.Valor;
                        break;
                }   
                queryString = queryString + ",";
            }
            queryString = queryString.Remove(queryString.Count() - 1, 1);
            var query = new HqlBasedQuery(typeof(T),QueryLanguage.Sql, queryString);
            results = (ArrayList)ActiveRecordMediator.ExecuteQuery(query);
        }
        catch (Exception exception)
        {
            throw new Exception(exception.Message);
        }
        return results;
    }
public class Consulta
{
    public enum TipoCampo
    {
        dato,
        numero
    }
    public string Campo { get; set; }
    public TipoCampo tipoCampo { get; set; }
    public string Valor { get; set; }
    public string Indicador { get; set; }
}
public void _Pruebastp()
    {
        var p = new Recurso().DevolverCamposDeObjetoSTP(
                                                         new Recurso(),
                                                         new List<Consulta> { new Consulta { Campo = "@nombre", tipoCampo = Consulta.TipoCampo.dato, Valor = "chr" }, new Consulta { Campo = "@perfil", tipoCampo = Consulta.TipoCampo.numero, Valor = "1" } },
                                                         "Ejemplo");
    }
