MySQL中的CONCAT函数用于将两个或多个字符串连接成一个字符串。它接受两个或多个参数,并将它们按顺序连接起来。模糊查询通常使用LIKE操作符来实现,结合CONCAT函数可以实现更复杂的模糊查询条件。 相关优势 灵活性:CONCAT函数允许你动态地构建查询字符串,适用于各种不同的查询需求。
一、concat()函数 1、功能:将多个字符串连接成一个字符串。 2、语法:concat(str1, str2,...) 返回结果为连接参数产生的字符串,如果有任何一个参数为null,则返回值为null。 3、举例: 例1:select concat (id, name, score) as info from tt2; 中间有一行为null是因为tt2表中有一行的score值为null。 例...
Learn how to use the CONCAT function in SQL to combine strings. Discover syntax, examples, and best practices for effective string manipulation.
Tip: To include delimiters (such as spacing or ampersands (&)) between the text you want to combine, and to remove empty arguments you don't want to appear in the combined text result, you can use the TEXTJOIN function. Remarks If the resulting string exceeds 32767 characters (cell limit...
