Answer 1

Simply Try With LEFT ,RIGHT ,CHARINDEX

select 
LEFT((RIGHT(a.name,((CHARINDEX('/', name))+1))),((CHARINDEX('.', (RIGHT(a.name, 
                     ((CHARINDEX('/', name))+1)))))-1)) splitstring,
a.name      
from 
   (select 'images/test.jpg' as name)a

Answer 2

You can try this:

Declare @test varchar(100)='images/test.jpg'
Select REPLACE(RIGHT(@test,charindex('/',reverse(@test))-1),'.jpg','')

Answer 3

Before

SELECT SUBSTRING(ParentBGBU,0,CHARINDEX('/',ParentBGBU,0)) FROM dbo.tblHCMMaster;

After

SELECT SUBSTRING(ParentBGBU,CHARINDEX('-',ParentBGBU)+1,LEN(ParentBGBU)) FROM dbo.tblHCMMaster

Answer 4

I found Royi Namir's answer useful but expanded upon it to create it as a function. I renamed the variables to what made sense to me but you can translate them back easily enough, if desired.

Also, the code in Royi's answer already handled the case where the character being searched from does not exist (it starts from the beginning of the string), but I wanted to also handle cases where the character that is being searched to does not exist.

In that case it acts in a similar manner by starting from the searched from character and returning the rest of the characters to the end of the string.

CREATE FUNCTION [dbo].[getValueBetweenTwoStrings](@inputString 
NVARCHAR(4000), @stringToSearchFrom NVARCHAR(4000), @stringToSearchTo 
NVARCHAR(4000))
RETURNS NVARCHAR(4000)
AS
BEGIN      
DECLARE @retVal NVARCHAR(4000)
DECLARE @stringToSearchFromSearchPattern NVARCHAR(4000) = '%' + 
@stringToSearchFrom + '%'

SELECT @retVal = SUBSTRING (
       @inputString,
       PATINDEX(@stringToSearchFromSearchPattern, @inputString) + LEN(@stringToSearchFrom),
       (CASE
            CHARINDEX(
                @stringToSearchTo,
                @inputString,
                PATINDEX(@stringToSearchFromSearchPattern, @inputString) + LEN(@stringToSearchFrom))
        WHEN
            0
        THEN
            LEN(@inputString) + 1
        ELSE
            CHARINDEX(
                @stringToSearchTo,
                @inputString,
                PATINDEX(@stringToSearchFromSearchPattern, @inputString) + LEN(@stringToSearchFrom))
        END) - (PATINDEX(@stringToSearchFromSearchPattern, @inputString) + LEN(@stringToSearchFrom))
   )
RETURN @retVal
END

Usage:

SELECT dbo.getValueBetweenTwoStrings('images/test.jpg','/','.') AS MyResult

Answer 5

Below query gives you data before '-' Ex- W12345A-4S

SELECT SUBSTRING(Column_Name,0, CHARINDEX('-',Column_Name))  as 'new_name'
from [abc].

Output - W12345A

Answer 6

use the following function

left(@test, charindex('/', @test) - 1)
