如何将多个表读入数据集中? [英] How can I read multiple tables into a dataset?

问题描述

我有一个返回多个表的存储过程.如何执行和读取这两个表?

我有这样的事情:

<上一页><代码>SqlConnection conn = new SqlConnection(CONNECTION_STRING);SqlCommand cmd = new SqlCommand("sp_mult_tables",conn);cmd.CommandType = CommandType.StoredProcedure);IDataReader rdr = cmd.ExecuteReader();

我不确定如何阅读它...处理此类查询的最佳方法是什么，我猜我应该将数据读入 DataSet?最好的方法是什么?

谢谢.

解决方案

改编自MSDN:

使用 (SqlConnection conn = new SqlConnection(connection)){SqlDataAdapter 适配器 = new SqlDataAdapter();adapter.SelectCommand = new SqlCommand(query, conn);适配器.填充(数据集)；返回数据集；}

I have a stored procedure that returns multiple tables. How can I execute and read both tables?

I have something like this:

SqlConnection conn = new SqlConnection(CONNECTION_STRING);
SqlCommand cmd = new SqlCommand("sp_mult_tables",conn);
cmd.CommandType = CommandType.StoredProcedure);

IDataReader rdr = cmd.ExecuteReader();

I'm not sure how to read it...whats the best way to handle this type of query, I am guessing I should read the data into a DataSet? How is the best way to do this?

Thanks.

解决方案

Adapted from MSDN:

using (SqlConnection conn = new SqlConnection(connection))
{
    SqlDataAdapter adapter = new SqlDataAdapter();
    adapter.SelectCommand = new SqlCommand(query, conn);
    adapter.Fill(dataset);
    return dataset;
}
