Subsonic SQL Server中是否缺少对亚音速3.0输出参数/默认参数的支持？

我有一个存储过程：

CREATE PROCEDURE MyProc ( @P1 uniqueidentifier, @P2 int = NULL output, @P3 int = NULL output )

---

C端的签名应该是Guid P1，int？P2，int？我想是P3。但它不是，它只是Guid，int，int。此外，输出参数不是作为输出参数创建的，它们只是直接的AddParameterP2，arg，DbType.Int32。这是为了工作吗？

好吧，看起来本机T4模板处理得不太好。事实上，我们在VS2003的时候建造了一些更复杂的东西，所以我将其更新为亚音速。其思想是，每个存储的proc都会获得一个类而不是一个函数，并且具有可为空的参数属性。我已经修改了几个模板，我确信我遗漏了一些东西，这不是生产质量，而是StoredProcedures.tt

下面是SQLServer.t中的GetSPParams函数

List<SPParam> GetSPParams(string spName){
    var result=new List<SPParam>();
    string[] restrictions = new string[4] { DatabaseName, null, spName, null };
    using(SqlConnection conn=new SqlConnection(ConnectionString)){
        conn.Open();
        var sprocs=conn.GetSchema("ProcedureParameters", restrictions);
        conn.Close();
        foreach(DataRow row in sprocs.Select("", "ORDINAL_POSITION")){
            SPParam p=new SPParam();
            p.SysType=GetSysType(row["DATA_TYPE"].ToString());
            p.DbType=GetDbType(row["DATA_TYPE"].ToString()).ToString();
            p.Name=row["PARAMETER_NAME"].ToString().Replace("@","");
            p.IsOutput=(row["PARAMETER_MODE"].ToString() == "INOUT");
            p.CleanName=CleanUp(p.Name);
            result.Add(p);
        }


    }
    return result;
}

public class SP{
    public string Name;
    public string CleanName;
    public string ClassName;
    public List<SPParam> Parameters;
    public SP(){
        Parameters=new List<SPParam>();
    }        
    public string ArgList{
        get{
            StringBuilder sb=new StringBuilder();
            foreach(var par in Parameters){
                    if (par.ShouldBeNullable) { continue; }
                if(sb.Length != 0)
                {
                    sb.Append(", ");
                }
                sb.AppendFormat("{0}{1} {2}", par.SysType, par.ShouldBeNullable ? "?" : "", par.CleanName);
            }
            return sb.ToString();
        }
    }
}
public class SPParam{
    public string Name;
    public string CleanName;
    public string SysType;
    public string DbType;
    public bool IsOutput;
    public bool ShouldBeNullable
    {
     get
     {
            return IsOutput && (SysType == "int" || SysType == "bool" || SysType == "double" || SysType == "long" || SysType == "short" || SysType == "decimal");
     }
    }
}

然后是Settings.ttinclude中的类声明

List<SPParam> GetSPParams(string spName){
    var result=new List<SPParam>();
    string[] restrictions = new string[4] { DatabaseName, null, spName, null };
    using(SqlConnection conn=new SqlConnection(ConnectionString)){
        conn.Open();
        var sprocs=conn.GetSchema("ProcedureParameters", restrictions);
        conn.Close();
        foreach(DataRow row in sprocs.Select("", "ORDINAL_POSITION")){
            SPParam p=new SPParam();
            p.SysType=GetSysType(row["DATA_TYPE"].ToString());
            p.DbType=GetDbType(row["DATA_TYPE"].ToString()).ToString();
            p.Name=row["PARAMETER_NAME"].ToString().Replace("@","");
            p.IsOutput=(row["PARAMETER_MODE"].ToString() == "INOUT");
            p.CleanName=CleanUp(p.Name);
            result.Add(p);
        }


    }
    return result;
}

public class SP{
    public string Name;
    public string CleanName;
    public string ClassName;
    public List<SPParam> Parameters;
    public SP(){
        Parameters=new List<SPParam>();
    }        
    public string ArgList{
        get{
            StringBuilder sb=new StringBuilder();
            foreach(var par in Parameters){
                    if (par.ShouldBeNullable) { continue; }
                if(sb.Length != 0)
                {
                    sb.Append(", ");
                }
                sb.AppendFormat("{0}{1} {2}", par.SysType, par.ShouldBeNullable ? "?" : "", par.CleanName);
            }
            return sb.ToString();
        }
    }
}
public class SPParam{
    public string Name;
    public string CleanName;
    public string SysType;
    public string DbType;
    public bool IsOutput;
    public bool ShouldBeNullable
    {
     get
     {
            return IsOutput && (SysType == "int" || SysType == "bool" || SysType == "double" || SysType == "long" || SysType == "short" || SysType == "decimal");
     }
    }
}

谢谢@Max，我对没有为params获取DbType感到沮丧。
