I just tried to bulk insert data which results to system.out.memory exception was thrown Even though the Ram as 260 GB and SQL Standard Edition 2017. Records was around 1 million , please give me any solution with my below code
DataTable table = new DataTable();
// read the table structure from the database
SqlDataAdapter adapter = new SqlDataAdapter("select * from xxxxx", constr);
adapter.SelectCommand.CommandTimeout = 0;
adapter.Fill(table);
Console.WriteLine();
Console.WriteLine(table.Rows.Count);
Console.WriteLine(" Table End time..");
Console.WriteLine(DateTime.Now);
Console.WriteLine("end----)";
Console.WriteLine();
SqlBulkCopy bulk = new SqlBulkCopy(constr2);
bulk.DestinationTableName = "xxxxxx";
bulk.WriteToServer(table);
Console.WriteLine()
