  For the following i am getting incorrect charindex in case of 2nd select charindex('a',N'aृ'). If any character preceds 'ृ ' character in Unicode, i am not able to get the Charindex correctly

  For the followin 1st stament return 1 as char index which is correct.

  for the 2nd it is retunring 0 as char index which is incorrect. The reason could be Unicode and preceds by special char 'ृ '

  for the 3rd getting the correct result 1. in this case also it is unicode but special char 'ृ ' is not the preceding charcter , it is at 3rd place

  for the 4th with char index for b is not coming becuase it is preceded with special char 'ृ '.

  Can some body explain me what is the issue with 2nd & 4th queries returning wrong results.

  select charindex('a','aृ')

  select charindex('a',N'aृ')

  select charindex('a',N'abृ')

  select charindex('b',N'abृ')

  Thanks in Advance

  Collation, Collation, Collation 😉

  try this : select CHARINDEX('a',N'a?' COLLATE latin1_general_bin)

  Your db collation most probably not compatible with the unicode characters you are using.
