按照指定字符截取字符串,截取出300

?

?業(yè)務(wù)需求:想比對圖片中框線部分是否一致

第一步 從最后一個/截取到末尾

select top 1 reverse(substring(reverse(ProcessControlName),1,charindex('/',reverse(ProcessControlName)) - 1)) from ProcessPublish;

--第二步 在第一步的基礎(chǔ)上從最后一個.截取
select RTRIM(LTRIM(reverse(substring(reverse(ProcessControlName),1,charindex('/',reverse(ProcessControlName)) - 1)))) as web端模板,RTRIM(LTRIM(reverse(substring(reverse(MobileFormTemplatePath),1,charindex('/',reverse(MobileFormTemplatePath)) - 1)))) as 手機(jī)端模板, *
from ProcessPublish
where ProcessID >2489 --新增加的"華濟(jì)建設(shè)"
and ProcessControlName != '' --模板不等于空,說明bpm發(fā)起的
and MobileFormTemplatePath != ''

?

--第三步 在第二步的基礎(chǔ)上獲取去掉.html字段
select top 1 (substring((substring(reverse(ProcessControlName),charindex('.',reverse(ProcessControlName))+1,len(reverse(ProcessControlName))-charindex('.',reverse(ProcessControlName)))),1,charindex('/',(substring(reverse(ProcessControlName),charindex('.',reverse(ProcessControlName))+1,len(reverse(ProcessControlName))-charindex('.',reverse(ProcessControlName))))) - 1)) from ProcessPublish

最后,完成

select (substring((substring(reverse(ProcessControlName),charindex('.',reverse(ProcessControlName))+1,len(reverse(ProcessControlName))-charindex('.',reverse(ProcessControlName)))),1,charindex('/',(substring(reverse(ProcessControlName),charindex('.',reverse(ProcessControlName))+1,len(reverse(ProcessControlName))-charindex('.',reverse(ProcessControlName))))) - 1)) as web端模板,
(substring((substring(reverse(MobileFormTemplatePath),charindex('.',reverse(MobileFormTemplatePath))+1,len(reverse(MobileFormTemplatePath))-charindex('.',reverse(MobileFormTemplatePath)))),1,charindex('/',(substring(reverse(MobileFormTemplatePath),charindex('.',reverse(MobileFormTemplatePath))+1,len(reverse(MobileFormTemplatePath))-charindex('.',reverse(MobileFormTemplatePath))))) - 1)) as 手機(jī)端模板, *
from ProcessPublish
where ProcessID >2489 --新增加的"華濟(jì)建設(shè)"
and ProcessControlName != '' --模板不等于空,說明bpm發(fā)起的
and MobileFormTemplatePath != ''
and (substring((substring(reverse(ProcessControlName),charindex('.',reverse(ProcessControlName))+1,len(reverse(ProcessControlName))-charindex('.',reverse(ProcessControlName)))),1,charindex('/',(substring(reverse(ProcessControlName),charindex('.',reverse(ProcessControlName))+1,len(reverse(ProcessControlName))-charindex('.',reverse(ProcessControlName))))) - 1)) != (substring((substring(reverse(MobileFormTemplatePath),charindex('.',reverse(MobileFormTemplatePath))+1,len(reverse(MobileFormTemplatePath))-charindex('.',reverse(MobileFormTemplatePath)))),1,charindex('/',(substring(reverse(MobileFormTemplatePath),charindex('.',reverse(MobileFormTemplatePath))+1,len(reverse(MobileFormTemplatePath))-charindex('.',reverse(MobileFormTemplatePath))))) - 1))

查出來有三處不一致
