, which defines the common properties and methods of all streams. The properties defined in the Tstream class are described below: (1) Size: This property returns the size of the data in the stream in bytes. (2) Position: This property controls the location of the access pointer in the stream. Four virtual methods defined in the Tstream class: (1) Read: This method realizes that the data is read out of

are other ways to load data into a SQL Server table, such as an INSERT statement, but in contrast SqlBulkCopy provides significant performance benefits. Use SqlBulkCopyClass can only write data to a SQL Server table. However, the data source is not limited to SQL Server; You can use any data source, as long as the

iv. Jumping Table Keywords: layer height random The jump table supports the average O (logn), the worst O (N) Complexity of node lookups, and the sequential operation to batch nodes.In most cases, the efficiency of the jump table can be comparable to the balance tree, because the implementation of the jumping table is more simple than the balance tree, so many programs use the Jumping table instead of the balance tree.Redis uses a jumpin

Second, compression and reduction 1. Compression progressive scan matrix, you can record a non-0 element. /blockquote> 2, restore traversing sequentially stored

This article illustrates the complete implementation of database data for the introduction of CI Framework sample. is for beginners to see, this is the easiest to pass the example. Share to everyone for your reference. The implementation methods are as follows: 1. Download CI framework 2. Configure database.php configuration: To set the connection parameter f

understand ( understandability), a set of conformance algorithm raft is designed for the target. The biggest feature of the raft algorithm is that it is simple to understand and simple to implement.2.2Raft Algorithm OverviewUnlike Paxos, raft emphasizes simplicity, raft and Paxos as long as the N/2+1 node is able to provide services.It is well known that when the problem is more complex, the problem can be decomposed into several small problems to deal with, Raft also uses the thought of divide

Two fork Sorting tree introduction We know that the binary tree, each node has a maximum of 2 Shang trees, known as the Saozi right subtree.The binary sort tree, apparently also a binary tree, has a more salient feature that renders sorting on the data field .In the two-fork sort tree , the data field of the left subtree of each tree is less than its root node value, and the

user to re-execute the data fetching process, but it also wastes a lot of time to execute, and sometimes even lets the user miss the task deadline! My implementation is to store the acquired data in the database every time, in the database to record the conditions of the query and the results of the query, after the final execution completes the bulk of the

To make a speech, look up some information. Java Speech api:http://java.sun.com/products/java-media/speech/ The Java Speech API allows developers to integrate voice technology into the user interface of Java applets and applications. This API provides a cross-platform interface to support command-control recognizers, dictation systems, and speech synthesizers. This integrated API is divided into several specifications: Java Speech API Specification (Java Speech API Specification,jsapi) Java S

the LUA implementation of data structure linked list in C + + list implementation write by nine Days Wild Goose Feather (jtianling)--Blog.csdn.net/vagrxie Vector I didn't implement it in Lua, it was awkward to implement a list. In fact, it's too much like the C + + standard library list, so it may not be a good feature of Lua, and a bit of a point is that the as

way is to find the ID first, and then in the query The code is as follows: The code is as follows Copy Code SELECT * FROM table WHERE ID in (10000, 100000, 1000000 ...); Share a little more.When querying a longer string for a field, add a field to the field in the table design, such as a field that stores the URLQuery, do not directly query the string, inefficient, you should find out the string of CRC32 or MD5 How to optimize MySQL tens quick paging Li
