汉字转全拼音函数优化方案(SQLServer),值得你看看

去年1月份时写了一篇关于优化汉字转拼音函数的解决方案,当时重点在于优化所举案例只能解决汉字转为拼音的首字母。

前不久收到这样一条短消息

随之我从(CSDN,CNBLOG,51CTO等)搜了几个解决方案,性能确实都不大理想。

首先还是感谢园友这个问题,接下来我就从网上抽取两个案例作优化说明

函数要求实现功能

select 函数名 ('你好,我是追索')

返回的结果(ni hao , wo shi zhui suo)

解决方案一：

/*
 根据汉字获取全拼
 1.生成所有读音临时表
 2.根据Chinese_PRC_CS_AS_KS_WS 排序获取读音
*/
create function dbo.fn_Getquanpin1(@str varchar(100))

end

测试了一串字符这个案例确实能达到汉字转拼音要求,但当我看到此函数内declare table、insert、order by等等这些耗性能的关键词让我感到头疼

我们还是来看看它的执行开销

估计子树大小大于5,这是多么惊人的一个数字。此执行计划后面跟着茫茫多的线条几乎全是表插入

我用一万条数据测试该函数等了我1分多钟都没执行完毕,可见该解决方案性能差到极点。

接下来我们看看解决方案二

测试了一串字符这个案例同样能达到汉字转拼音要求,该解决方案还好没让我看到表插入,这回性能应该大有提高

我们来看那看它的执行开销

果然不出所料,估计子树大小在0.017左右, 其中排序开销最大

我用一万条数据测试该函数花了10秒左右

既然排序开销最大那就优化该解决方案去掉order by。

这时估计子树大小就在0.00001之下了，可你会发现此解决方案再怎么优化还是免不了需要常量扫描,where筛选等运算.

我用一万条数据测试该优化后函数花了4～5秒左右

出于对性能要求的不满足,打开工具我自己写了一个汉字转拼音的函数

由于时间仓促未加任何注释,有问题可及时提出

最后给出的就是重写的解决方案

我们来看它的执行计划

没有排序,没有常量扫描,没有筛选器,没有计算标量

估计子树大小为0

我用一万行测试数据花0~2秒就把所有汉字转换为拼音

案例三 首字母大写
