如何将表从存储过程检索到数据表？ [英] How can I retrieve a table from stored procedure to a datatable?

问题描述

我创建了一个存储过程以便为我返回一个表。

I created a stored procedure so as to return me a table.

类似这样的事情：

create procedure sp_returnTable
body of procedure
select * from table
end

当我在前端调用此存储过程时，需要写什么代码才能在数据表对象中检索它？

When I call this stored procedure on the frontend what code do I need to write to retrieve it in a datatable object?

我写了类似下面的代码。我基本上想知道如何将表检索和存储到数据表的对象中。我所有的查询都在运行，但是我不知道如何通过存储过程将表检索到数据表中。

I wrote code something like the following. I basically want to know retrieving and storing table into an object of datatable. All my queries are running, but I don't know how to retrieve table into a datatable through a stored procedure

DataTable dtable = new DataTable();
cmd.Connection = _CONN;

cmd.CommandText = SPNameOrQuery;
cmd.CommandType = CommandType.StoredProcedure;

SqlDataAdapter adp = new SqlDataAdapter(cmd);
OpenConnection();
adp.Fill(dtTable);
CloseConnection();

在此代码中，命令已与存储过程名称及其参数绑定在一起。会从存储过程中返回数据表吗？

Here in this code a command has been bound with the stored procedure name and its parameters. Will it be returning me a datatable from the stored procedure?

推荐答案

string connString = "<your connection string>";
string sql = "name of your sp";

using(SqlConnection conn = new SqlConnection(connString)) 
{
    try 
    {
        using(SqlDataAdapter da = new SqlDataAdapter()) 
        {
            da.SelectCommand = new SqlCommand(sql, conn);
            da.SelectCommand.CommandType = CommandType.StoredProcedure;

            DataSet ds = new DataSet();   
            da.Fill(ds, "result_name");

            DataTable dt = ds.Tables["result_name"];

            foreach (DataRow row in dt.Rows) {
                //manipulate your data
            }
        }    
    } 
    catch(SQLException ex) 
    {
        Console.WriteLine("SQL Error: " + ex.Message);
    }
    catch(Exception e) 
    {
        Console.WriteLine("Error: " + e.Message);
    }
}
