MySQL中字符串函数详细介绍
如：在串中查找某个子串、求取一个子串、在串的某个位置上插入一个子串以及删除一个子串等。两个字符串相等的充要条件是：长度相等，并且各个对应位置上的字符都相等。设p、q是两个串，求q在p中首次出现的位置的运算叫做模式匹配。串的两种最基本的存储方式是顺序存储方式和链接存储方式。-MySQL string functions in detail, such as: in the string to find a substring, to strike a substring in a string position to insert a substring, and delete a substring and so on. Two strings are equal and sufficient conditions are: equal length, and each character corresponding positions are equal. Let p, q are two strings, find q in p position of the first occurrence of computing called pattern matching. Strings are stored are two basic ways and links stored sequentially stored.
