All of the previous examples have dealt with textual or character data: You wrote and read character strings. 前面所有的示例都处理文本数据或字符数据:写入和读取字符string。
It first explains key concepts, such as character and byte semantics with respect to string data. 首先解释一些关键概念,比如字符和字符串数据的字节语义。
A string data that has a partial character can be called an incomplete string data. 可以将拥有部分字符的字符串数据称为不完整的字符串数据。
Character vs byte semantics of string data 字符与字符串数据的字节语义之间的对比
The description column is a variable-length character string, so it expects a string ( which you indicate by enclosing the character data within single quotes). description列是长度可变的字符串,所以它预计是一个字符串(通过将字符数据括在单引号中指明)。
Unlike the LENGTH function, the CHARACTER_LENGTH does not accept input data that is not string based. 与LENGTH函数不同,CHARACTERLENGTH只接受基于字符串的输入数据。
However, if the column is a character data type and contains only numeric characters, you can indicate this by setting the NUMERIC_STRING option to'Y. ' 然而,如果列是字符数据类型,并且只包含数字字符,那么可以通过将NUMERICSTRING选项设置为“Y”来表明这一点。
In a character string, to reduce the space taken on a data medium by repetitive characters. 减少字符串中由于字符的重复出现而占据的数据媒体空间。
It introduced research actual state of genetic algorithms, enumerated the calculation result of global optimized crossover and mutation, gave the mostly program of binary system character string coding and using numerical model and the practical data checked out the effectiveness of mixed inversion algorithm. 文中介绍了遗传算法的研究现状,例举了全局寻优交叉和变异的计算结果,给出了二进制字符串编码的主要程序段,用数值模型与实际资料验正了混合反演算法的有效性。
Aiming at the character of the string data in the web page, a detailed algorithm for splitting the Chinese-English mixed string is given to implement Chinese layout. 针对网页中字符数据元素的特点,设计了中英文混合字符串分割算法,实现了网页排版对中文的支持。
New High Efficient Sorting Algorithm by Grading to Character String Data 针对字符串等复杂数据的一种新的高效分档混合排序算法
Then the character of neural network and pattern matching is analyzed, the neural network is fit to detect the intrusion based on the statistical feature of network flux, and the pattern matching detects the intrusion by searching specific character string in the data packet. 然后分析了神经网络和模式匹配技术的特点,神经网络适合检测具有统计特性的入侵行为;而模式匹配技术通过在数据包中搜索特征字符串来检测入侵。
NT technique was used in the SQL server 2000 library design and management of clients 'port in windows 2000 server operating system. The data communality was carried about by means of using character string form of data; 利用最新流行的NT技术在Windows2000Server操作系统中进行数据库服务器端的SqlServer2000数据库设计和管理:数据的字段化抽象实现了数据的一致性;
