DECLARE @keysValueToSearch NVARCHAR(4000) = '/'
DECLARE @untilThisCharAppears NVARCHAR(4000) = '.'
DECLARE @keysValueToSearchPattern NVARCHAR(4000) = '%' + @keysValueToSearch + '%'


 --Nothing to touch here     
SELECT SUBSTRING(
           @a,
           PATINDEX(@keysValueToSearchPattern, @a) + LEN(@keysValueToSearch),
           CHARINDEX(
               @untilThisCharAppears,
               @a,
               PATINDEX(@keysValueToSearchPattern, @a) + LEN(@keysValueToSearch)
           ) -(PATINDEX(@keysValueToSearchPattern, @a) + LEN(@keysValueToSearch))
       )
