基于SQL Server的字符统计方法研究

The Research of Characters Statistical Methods Based on SQL Server

在数据库操作过程中存在大量的字符及字符串统计,由于SQL语句本身并不擅长解决这些字符串操作,所以在SQL中字符串的操作往往非常繁琐,但是DBMS都提供了一些内置函数。本文以SQL Server为例,从实际出发分析了一些字符串处理函数的使用技巧并给出了具体的实例。

In the database processing, there are a lot of character and string Statistics. Since the SQL statement itself is not good at solving these string operations, the string will always be cumbersome to operate. However, DBMS provides a number of built-in functions. This paper takes SQL Server as an example, gives the usage skills of string handling functions and specific examples according to the practical analysis.
