Below is a sample usage of the SqlDataReader class in ADO.Net.
reader.HasRows checks if any rows are returned.
string connectionString = "Data Source=DataBaseServerName;Initial Catalog=DataBaseName;Persist Security Info=True;User ID=UserName;Password=Password;";
string query = "select eid, name, email from dbo.Employee where status=1";
try
{
using (SqlConnection connection = new SqlConnection(connectionString))
{
SqlCommand command = new SqlCommand(query, connection);
connection.Open();
SqlDataReader reader = command.ExecuteReader();
if (reader.HasRows)
{
while (reader.Read())
{
Console.WriteLine("Column1 : {0} | Column2 : {1} | Column3 : {2}", reader[0], reader[1], reader[2]);
}
}
reader.Close();
}
}
reader.HasRows checks if any rows are returned.
string connectionString = "Data Source=DataBaseServerName;Initial Catalog=DataBaseName;Persist Security Info=True;User ID=UserName;Password=Password;";
string query = "select eid, name, email from dbo.Employee where status=1";
try
{
using (SqlConnection connection = new SqlConnection(connectionString))
{
SqlCommand command = new SqlCommand(query, connection);
connection.Open();
SqlDataReader reader = command.ExecuteReader();
if (reader.HasRows)
{
while (reader.Read())
{
Console.WriteLine("Column1 : {0} | Column2 : {1} | Column3 : {2}", reader[0], reader[1], reader[2]);
}
}
reader.Close();
}
}
