//执行数据库操作：

Database db = DatabaseFactory.CreateDatabase();

//执行存储过程

DbCommand cmd = db.GetStoredProcCommand("存储过程名");

//执行Sql语句

  DbCommand cmd = db.GetSqlStringCommand(sql);

db.AddInParameter(cmd, "物品编号", DbType.String, ProductID);
object ojb = db.ExecuteScalar(cmd);

例如：

public void AdLoadByQualification(string _AdLoadByQualification, string _Order)
{
Database db = DatabaseFactory.CreateDatabase();
DbCommand cmdTxt = db.GetStoredProcCommand("Ad_LoadByQualification");
db.AddInParameter(cmdTxt, "@AdLoadByQualification", DbType.String, _AdLoadByQualification);
db.AddInParameter(cmdTxt, "@AdLoadByQualification", DbType.String, _Order);
db.ExecuteNonQuery(cmdTxt);
}
