Seeding SQLite RANDOM()

问题 Does SQLite support seeding the RANDOM() function the same way MySQL does with RAND() ? $query = "SELECT * FROM table ORDER BY RAND(" . date('Ymd') . ") LIMIT 1;"; From the MySQL Manual about RAND(N) : If a constant integer argument N is specified, it is used as the seed value, which produces a repeatable sequence of column values. In the following example, note that the sequences of values produced by RAND(3) is the same both places where it occurs. If not, is there any way to archive the

This question already has an answer here: What does 'seeding' mean? 4 answers What is a seed in terms of generating a random number? I need to generate hundreds to thousands of random numbers, I have read a lot about using a "seed". What is a seed? Is a seed where the random numbers start from? For example if I set my seed to be 5 will it generate numbers from 5 to whatever my limit is? So it will never give me 3 for example. I am using C++, so if you provide any examples it'd be nice if it was in C++. Thanks! What is normally called a random number sequence in reality is a "pseudo-random"

MVC 5 Seed Users and Roles

I have been playing about with the new MVC 5, I have a few models, controller and views setup using code first migrations. My question is how do I seed users and roles? I currently seed some reference data in my Seed method in Configuration.cs. But it looks to me that the user and roles tables are not created until something first hits the AccountController. I currently have two connection strings so I can separate my data from my authentication into different databases. How can I get the user, roles, etc tables populate along with my others? And not when the account controller is hit? Valin
