System.InvalidOperationException: Connection must be valid and open.

[Alejandro Penate-Diaz]

Hi.

I am using this function tu execute updates to a MySql database from a sql
string, but I am getting a System.InvalidOperationException: Connection
must be valid and open.

Database queries work fine, but I cant update the source. Am I missing
something?

Thanks, Alejandro.

public static bool updateSource(string sql)

{

MySqlConnection conn = new MySqlConnection(myConnectionString);

MySqlCommand command = new MySqlCommand(sql,conn);

command.CommandType = CommandType.Text;

try

{

command.ExecuteNonQuery();

return true;

}

catch (Exception)

{return false;}

finally

{

conn.Close();

}

Sorry, just missed Connection.Open() because wasn't using DataAdapter.Fill()
;-)
