Summary:
When an object is persisted to the database, the identifier of the object is always difficult to implement properly. However, the problem is entirely derived from the existence of objects that do not hold IDs before they are saved. We can solve this problem by taking responsibility for assigning object IDs from an object-relational image framework such as hibernate. In contrast, once an object is instantiated, it should be assigned an ID. Th

Using Gridfs file to MongoDB, return a Mongoid object, usually we need to save the $id value in this object in a string form to the database, as the identity of the file, then how does PHP take out the ID string value of the Mongoid object?
Find specific records in MongoDB in PHP via _id:
Query conditions need to be written like this: Array ("_id" =>new mongoid ("$id
Anyone who has studied Windows programming knows that processes in Windows can have a parent-child relationship, a process that has a parent-child relationship, and a child process that exits when the parent process ends. But if there is no parent-child relationship between processes, how do we let the child process exit at the same time as the parent process exits? There are a number of methods, this article describes one of the scenarios using the parent process

But there are ways to get the container ID through the PID. There are two possibl

This article describes the way PHP implements MongoDB customization to generate the self-increasing ID. Share to everyone for your reference. The specific analysis is as follows:
Copy Code code as follows:

You can see if it's successful.

This is a problem when doing a skin-changing function.
For skin change, there are examples on the web that can be read from other skin packages, provided that you must first hold the reference name of the resource, like R.drawable.background (hey, this is not nonsense). The principle of this skin-changing scheme is that the resource name of the application is R.drawable.background, the skin package should also be the name, and then through this name to get the resource in the skin package of th

Although we login to the Linux host, the input is our account, but in fact, the Linux host does not directly know your "account name", it only know the ID. The correspondence between ID and account is in/etc/passwd.
At least two IDs are obtained for each logged-on user, one for the user ID (UserID, short uid) and one for the user group
The application scenario is this:For example, I have a table: Sm_position has a certain amount of historical data.

Now you need to import new data. And the new data. ID is man 1 start. Because the ID starts at 1134 when the Sm_position table is imported. There is no way to export direct
