c++ - Generating unique ID in postgres -

Is there any way to generate a unique ID in postgres? Suppose I have two files:

File 1:
a, b, c, d, e, f

file2:
h, i, j < Br> a, f, h

and I want to include them in the same table (which should be possible because they have the same data type elements) but still able to obtain them, Separately later, can I get postgrescale for generating a unique ID for me?

You can definitely do it! You can create a loaded_files table and you can store the name of the file you are loading ID from loaded_files and Insert that data into your file_items table.

What you are asking is a solution that is usually solved during data loading in the application code or with other SQL statements.

Integrate flash games in android app? -



    3 is a flash game that I want to integrate into a menu / list in the Android app. So when the user selects the game from the list, the game starts with the help of the Android Flash Player.   Is it better or better with webwave?   Is there any good tutorial?   Thank you! Adobe Flash provides a good way: you can create a breeze for the Android app.    Use this to create your menu and compile three games in your air app.   Here are some tutorial links about how to publish AiI for Android applications and:   PART1: AIR for Android, PART2:   Publication for Android apps: Ai:   I do not believe that the Android Flash Player can be launched with a single intention so far, so using Java Android will not solve it (now ) And   and a third approach Whatever you mentioned, it should work - using the webwave.
