How can I retrieve a table from stored procedure to a datatable?
.net, ado.net, asp.net, c#, sql-server
Solution
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);
}
}

Problem
I created a stored procedure so as to return me a table. Something like this: ``` create procedure sp_returnTable body of procedure select * from table end ``` When I call this stored procedure on the frontend what code do I need to write to retrieve it in a datatable object? 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(); ``` 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?
