单个sql查询作为数据集中的多个表返回

Question

I was wondering if i can use a single query in sql server 2005 to return as a dataset in c#, asp.net 2005 into different tables.

DataSet ds = new DataSet();
ds = new BusinessLogic.BizLogic().getData(int repID);
for(ds != null)
{
    txtDate.Text = ds.Tables[2].Rows[0]["Date"].ToString();
}

Want to figure out, how to write the store procedure to have multiple tables.A simple example would be appreciated. Thank you!

Answer 1

You absolutely can, although you may want to consider the overall goal and implications of considering this design.

In your stored procedure you just simply have multiple selects ala..

select xxx, yyy from table1
select zzz, nnn from table2

Along those lines.

Answer 2

Yes its easy, you can do it via a proc or via inline sql, but like the above poster said, consider the implications.

 using (var sqlConn = new SqlConnection("Server=localhost;Database=Test;Integrated Security=SSPI"))
            {
                sqlConn.Open();
                string sql = "Select * From table1; Select * From table2;";
                using (var sqlCmd = new SqlCommand(sql, sqlConn))
                {
                    var da = new SqlDataAdapter(sqlCmd);
                    var ds = new DataSet();
                    da.Fill(ds);
                    Console.WriteLine(ds.Tables.Count); // Will show 2 !

                }

            }
