Can u please try like this,

SQL

DECLARE @regex NVARCHAR(100)
SET @regex = N'^([\w-\.]+)@((\[[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.)|(([\w-]+\.)+))([a-zA-Z]{2,4}|[0-9]{1,3})(\]?)$'

Try this:

SQL

SELECT
  EmailAdd,
  CASE WHEN EmailAdd LIKE '%_@_%_.__%'
       AND EmailAdd NOT LIKE '%[Invalid Chars]%'
  THEN 'Email Address is Correct'
  ELSE 'Invalid Email Address'
  END AS 'MSG'
FROM
  Table1

Refer this[^] for SQL Server function to validate email addresses.

All the best.

Solution 4

Solution 2, I added
WHEN @Email is null then 0 --NULL Email is invalid
WHEN CHARINDEX('@', @Email) = 1 then 0 -- <-- I ADDED

too avoid this SELECT dbo.udf_ValidateEmail('@bellsouth.net')
