Answer 1

Here is another Microsoft SQL function:
CREATE FUNCTION PROPERCASE(#TEXT AS VARCHAR(MAX))
RETURNS VARCHAR(MAX)
AS
BEGIN
DECLARE #RESET BIT;
DECLARE #STR VARCHAR(MAX);
DECLARE #I INT;
DECLARE #C CHAR(1);
SELECT #RESET = 1, #I=1, #STR = '';
WHILE (#I <= LEN(#TEXT))
SELECT #C= SUBSTRING(#TEXT,#I,1),
#STR = #STR + CASE WHEN #RESET=1 THEN UPPER(#C) ELSE LOWER(#C) END,
#RESET = CASE WHEN #C LIKE '[A-ZA-Z]' THEN 0 ELSE 1 END,
#I = #I +1
RETURN #STR
END

Answer 2

There's no such function in any database which do this for you. You've to write a function which actually performs the check on each word in a sentence. Please check the solutions below:
MySql:
DELIMITER //
CREATE FUNCTION CAP_FIRST (input VARCHAR(255))
RETURNS VARCHAR(255)
DETERMINISTIC
BEGIN
DECLARE len INT;
DECLARE i INT;
SET len = CHAR_LENGTH(input);
SET input = LOWER(input);
SET i = 0;
WHILE (i < len) DO
IF (MID(input,i,1) = ' ' OR i = 0) THEN
IF (i < len) THEN
SET input = CONCAT(
LEFT(input,i),
UPPER(MID(input,i + 1,1)),
RIGHT(input,len - i - 1)
);
END IF;
END IF;
SET i = i + 1;
END WHILE;
RETURN input;
END//
DELIMITER ;
Example:
SELECT CAP_FIRST('this is exACtly tHe same!')
Output:
This Is Exactly The Same!

Hope this helps!

This SQL should work.
SELECT UPPER(LEFT(<ColumnName>, 1)) + LOWER(RIGHT(<ColumnName>,LEN(<ColumnName>)-1)) FROM {YourTableName}

Answer 4

First you need to create function
CREATE FUNCTION ProperCase(#OriginalText VARCHAR(8000))
RETURNS VARCHAR(8000)
BEGIN
DECLARE #CleanedText VARCHAR(8000)
;with
a1 as (select 1 as N union all select 1 union all
select 1 union all select 1 union all
select 1 union all select 1 union all
select 1 union all select 1 union all
select 1 union all select 1),
a2 as (select 1 as N from a1 as a cross join a1 as b),
a3 as (select 1 as N from a2 as a cross join a2 as b),
a4 as (select 1 as N from a3 as a cross join a2 as b),
Tally as (select top (len(#OriginalText)) row_number() over (order by N) as N from a4)
SELECT #CleanedText = ISNULL(#CleanedText,'') +
--first char is always capitalized?
CASE WHEN Tally.N = 1 THEN UPPER(SUBSTRING(#OriginalText,Tally.N,1))
WHEN SUBSTRING(#OriginalText,Tally.N -1,1) = ' ' THEN UPPER(SUBSTRING(#OriginalText,Tally.N,1))
ELSE LOWER(SUBSTRING(#OriginalText,Tally.N,1))
END
FROM Tally WHERE Tally.N
Now you just use this function
select dbo.ProperCase('My nAme is iShAn halaRNkar')
