Check the below input string and expected output for counting the total Lowercase, Uppercase and Other Characters (Including SPACE) in the given string.

Input String:

'I am Anvesh Patel, owner @str DBRND.COM'

Expected Output:

UpperCase_Count LowerCase_Count OtherCharacter_Count
--------------- --------------- --------------------
11              19              9

Solution:

DECLARE @str AS VARCHAR(100) = 'I am Anvesh Patel, owner @str DBRND.COM'
 
SELECT 
        SUM(CASE WHEN ASCII(string) BETWEEN 65 AND 90 THEN 1 ELSE 0 END) as UpperCase_Count
       ,SUM(CASE WHEN ASCII(string) BETWEEN 97 AND 122 THEN 1 ELSE 0 END) as LowerCase_Count
       ,SUM(CASE WHEN (( ASCII(string) NOT BETWEEN 97 AND 122 ) AND ( ASCII(string) NOT BETWEEN 65 AND 90 )) THEN 1 ELSE 0 END) as OtherCharacter_Count 
FROM
(
    SELECT 
		DISTINCT Number 
		,SUBSTRING(@str,Number,1) as string
    FROM Master..spt_Values 
    WHERE Number > 0 and number <= LEN(@str)
)as t
