php - Should you always end mysql queries with "or die?" -

-

Example queries end in some tutorials: 

  or die (mysql_error ( ));

I can see that you sometimes want to do this, but they also use it for questions which should not really cause any problem. Is it always a good practice to use it, or are they just doing it to help you learn it?

itemprop = "text">

No

Avoid at all costs!

  1. This is a horrible message to show the end user

    3. The first transfers money from X to Y and succeeds, secondly, it will have to subtract X from wi fail .

    You have no way to return the transaction and the error is not logged. Effective user u happy and left x, where money went confused ...

    Use a sensible error management for questions - either to create a class that uses ORM for you or Will do

oracle - The fastest way to check if some records in a database table? -

-
I have a big table to work with. I have to see that there are some records whose parent_id is equal to my passing value. Currently I do this by implementing "my_table using select count (*) where parent_id =: id"; If the result> 0, it means that they exist. Because this is a very large table, and I do not care what the actual number of records present, I just want to know if it exists, so I think count (*) Bit is disabled. How do I apply this requirement most quickly? I'm using Oracle 10. # Tips for Hibernation & amp; Tricks It suggests writing in such a way: Integer number = (integer) session .createQuery ("Select Count (*) to ...."). UniqueResult (); I do not know what is the magic of the unique rule? Why does it fast? To compare, select "1 from mytable where parent_id = passId and rowrum", which is more efficient? If you are not interested in the number of records, then there is an EXISTS query one: Select 'y'
