Generate MD5 hash string with T-SQL

Question

Is there a way to generate MD5 Hash string of type varchar(32) without using fn_varbintohexstr

SUBSTRING(master.dbo.fn_varbintohexstr(HashBytes('MD5', '[e-mail]')), 3, 32)

So it could be used inside a view with SCHEMABINDING

Answer 1

SELECT CONVERT(
      VARCHAR(32),
      HASHBYTES(
                   'MD5',
                   CAST(prescrip.IsExpressExamRX AS VARCHAR(250))
                   + CAST(prescrip.[Description] AS VARCHAR(250))
               ),
      2
  ) MD5_Value;

works for me.

select LOWER(CONVERT(VARCHAR(32), HashBytes('MD5', CONVERT(varchar, EmailAddress)), 2)) from ...
