I want to find out English text present in umsg column.

Answer 1

check below :

;WITH CTE
 AS (
 SELECT ID,
        DATE,
        umsg,
        CASE
            WHEN(CAST(umsg AS VARCHAR(MAX)) COLLATE SQL_Latin1_General_Cp1251_CS_AS) = umsg
            THEN 0
            ELSE 1
        END HasSpecialChars
 FROM )
 SELECT ID,
        DATE,
        umsg
 FROM CTE
 WHERE Date >= '01/01/2014'
       AND Date < '09/26/2017'
       AND HasSpecialChars = 0;

Desired Output :
