Step by Step -104-sql statement (Intercept string)

Intercepts a string by the specified character and intercepts 300

Business requirements: Want to match the frame line part of the picture

First step from last/intercept to end

Select top 1 reverse (substring (reverse (processcontrolname), 1,charindex ('/', reverse (processcontrolname))-1) from Processpublish;

--The second step is based on the first step from the last one. Intercept
Select RTRIM (LTRIM (Reverse (substring (reverse), processcontrolname ('/', 1,charindex (reverse))-1 )))) as Web-side templates, RTRIM (LTRIM (Reverse (substring (reverse), Mobileformtemplatepath ('/', 1,charindex ( Mobileformtemplatepath)))))) as a mobile-phone template, *
From Processpublish
where ProcessID >2489--The newly added "Hua Ji construction"
and processcontrolname! = "--the template is not equal to NULL, stating that BPM originated
and Mobileformtemplatepath! = "'

--The third step is to get rid of it on the basis of the second step. HTML fields
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

Finally, complete

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-side templates,
(SUBSTRING (substring (reverse (mobileformtemplatepath), charindex ('. ', reverse (Mobileformtemplatepath)) +1,len ( Reverse (Mobileformtemplatepath))-charindex ('.

and (SUBSTRING (substring (reverse (processcontrolname), charindex ('. ', reverse (processcontrolname)) +1,len (Reverse ( Processcontrolname))-charindex ('.
