What is the most direct route to get a DataSet if I have a sql command?
string sqlCommand = "SELECT * FROM TABLE";
string connectionString = "blahblah";
DataSet = GetDataSet(sqlCommand,connectionString);
GetDataSet()
{
//...?
}
I started with SqlConnection
and SqlCommand
, but the closest thing I see in the API is SqlCommand.ExecuteReader()
. With this method, I'll need to get a SqlDataReader
and then convert this to a DataSet
manually. I figure there is a more direct route to accomplish the task.
If easier, a DataTable
will also fit my goal.
Just finish it up.
string sqlCommand = "SELECT * FROM TABLE";
string connectionString = "blahblah";
DataSet ds = GetDataSet(sqlCommand, connectionString);
DataSet GetDataSet(string sqlCommand, string connectionString)
{
DataSet ds = new DataSet();
using (SqlCommand cmd = new SqlCommand(
sqlCommand, new SqlConnection(connectionString)))
{
cmd.Connection.Open();
DataTable table = new DataTable();
table.Load(cmd.ExecuteReader());
ds.Tables.Add(table);
}
return ds;
}
public static string textDataSource = "Data Source=localhost;Initial Catalog=TEST_C;User ID=sa;Password=P@ssw0rd";
public static DataSet LoaderDataSet(string StrSql)
{
SqlConnection cnn;
SqlDataAdapter dad;
DataSet dts = new DataSet();
cnn = new SqlConnection(textDataSource);
dad = new SqlDataAdapter(StrSql, cnn);
try
{
cnn.Open();
dad.Fill(dts);
cnn.Close();
return dts;
}
catch (Exception)
{
return dts;
}
finally
{
dad.Dispose();
dts = null;
cnn = null;
}
}
