In actual development , we often provide an interface for selecting the data source and data connection configuration in the application to facilitate the user to configure the database connection string. A typical approach is to write this information in an XML configuration file , such as a web.config or app.config file . But the customer is not a professional programmer , accidentally will make th

As a programmer, a reference to "caching" can easily be associated with "client (browser caching)" and "Server Caching". Client-side caching is the browser temporary folder on the computer's hard disk, and the server cache exists in the server's memory, and of course there are special caching servers in some advanced applications, even the implementation of caching using the database. Of course, none of this is in the scope of this article, this artic

, student and teacher will be placed in different bucket, and dog and God will be placed in the same bucket. So when an index key is the only performance that gets an element from Hashtable, it behaves better. [1] The advantage of the hash table is that the space is changing time, the following conditions need to be noted when designing a hash table [2]: 1 hash function selection, a good hash function can evenly hash the data sample into the table; 2

A recent Ajax call has been made in asp.net: The client side first takes a page template from the ASP.net server and then takes some relevant data from the server when the page is initialized to implement the dynamic display of the page template. The specific implementation is: 1 Client to ASP. NET background send HTTP GET instructions 2 Send an HTML template to the client in the background while storing

database as an example of the situation explained:1. If the fields of the 2 tables are consistent and you want to insert all the data, you can use this method:INSERT into SELECT * from source table; Insert into Select * from InsertTest2;2. If you want to import only the specified fields, you can use this method:INSERT into SELECT from source table; (the field must be consistent in this case) Insert into Select from InsertTest2;3. If you
