sql和mysql在ado.net参数化查询的小区别

String s1 = "select count(*) from  user where id=@i ";

using (SQLCommand command= new SQLCommand(s1, conn)) {
     command.Parameters.Add(new SqlParameter ("id",1));}
在sql中,new SqlParameter("id",1)第一个参数id是不用@符号的;

而在mysql中,则需要@
using (MySQLCommand cmd2 = new MySQLCommand(s1, conn))                  {
     cmd2.Parameters.Add(new MySQLParameter ("@i",1));}
