SQL Server: Make all UPPER case to Proper Case/Title Case

Question

I have a table that was imported as all UPPER CASE and I would like to turn it into Proper Case. What script have any of you used to complete this?

Answer 1

This function:

• "Proper Cases" all "UPPER CASE" words that are delimited by white space
• leaves "lower case words" alone
• works properly even for non-English alphabets
• is portable in that it does not use fancy features of recent SQL server versions
• can be easily changed to use NCHAR and NVARCHAR for unicode support,as well as any parameter length you see fit
• white space definition can be configured

CREATE FUNCTION ToProperCase(@string VARCHAR(255)) RETURNS VARCHAR(255)
AS
BEGIN
  DECLARE @i INT           -- index
  DECLARE @l INT           -- input length
  DECLARE @c NCHAR(1)      -- current char
  DECLARE @f INT           -- first letter flag (1/0)
  DECLARE @o VARCHAR(255)  -- output string
  DECLARE @w VARCHAR(10)   -- characters considered as white space

  SET @w = '[' + CHAR(13) + CHAR(10) + CHAR(9) + CHAR(160) + ' ' + ']'
  SET @i = 1
  SET @l = LEN(@string)
  SET @f = 1
  SET @o = ''

  WHILE @i <= @l
  BEGIN
    SET @c = SUBSTRING(@string, @i, 1)
    IF @f = 1 
    BEGIN
     SET @o = @o + @c
     SET @f = 0
    END
    ELSE
    BEGIN
     SET @o = @o + LOWER(@c)
    END

    IF @c LIKE @w SET @f = 1

    SET @i = @i + 1
  END

  RETURN @o
END

Result:

dbo.ToProperCase('ALL UPPER CASE and    SOME lower ÄÄ ÖÖ ÜÜ ÉÉ ØØ ĈĈ ÆÆ')
-----------------------------------------------------------------
All Upper Case and      Some lower Ää Öö Üü Éé Øø Cc Ææ

Answer 2

Here's a UDF that will do the trick...

create function ProperCase(@Text as varchar(8000))
returns varchar(8000)
as
begin
  declare @Reset bit;
  declare @Ret varchar(8000);
  declare @i int;
  declare @c char(1);

  if @Text is null
    return null;

  select @Reset = 1, @i = 1, @Ret = '';

  while (@i <= len(@Text))
    select @c = substring(@Text, @i, 1),
      @Ret = @Ret + 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 @Ret
end

You will still have to use it to update your data though.

Answer 3

UPDATE titles
  SET title =
      UPPER(LEFT(title, 1)) +
        LOWER(RIGHT(title, LEN(title) - 1))

Answer 4

If you can enable the CLR in SQL Server (requires 2005 or later) then you could create a CLR function that uses the TextInfo.ToTitleCase built-in function which would allow you to create a culture-aware way of doing this in only a few lines of code.

Answer 5

I know this is late post in this thread but, worth looking. This function works for me ever time. So thought of sharing it.

CREATE FUNCTION [dbo].[fnConvert_TitleCase] (@InputString VARCHAR(4000) )
RETURNS VARCHAR(4000)
AS
BEGIN
DECLARE @Index INT
DECLARE @Char CHAR(1)
DECLARE @OutputString VARCHAR(255)

SET @OutputString = LOWER(@InputString)
SET @Index = 2
SET @OutputString = STUFF(@OutputString, 1, 1,UPPER(SUBSTRING(@InputString,1,1)))

WHILE @Index <= LEN(@InputString)
BEGIN
    SET @Char = SUBSTRING(@InputString, @Index, 1)
    IF @Char IN (' ', ';', ':', '!', '?', ',', '.', '_', '-', '/', '&','''','(')
    IF @Index + 1 <= LEN(@InputString)
BEGIN
    IF @Char != ''''
    OR
    UPPER(SUBSTRING(@InputString, @Index + 1, 1)) != 'S'
    SET @OutputString =
    STUFF(@OutputString, @Index + 1, 1,UPPER(SUBSTRING(@InputString, @Index + 1, 1)))
END
    SET @Index = @Index + 1
END

RETURN ISNULL(@OutputString,'')
END

Test calls:

select dbo.fnConvert_TitleCase(Upper('ÄÄ ÖÖ ÜÜ ÉÉ ØØ ĈĈ ÆÆ')) as test
select dbo.fnConvert_TitleCase(upper('Whatever the mind of man can conceive and believe, it can achieve. – Napoleon hill')) as test

Results:

Answer 6

I am a little late in the game, but I believe this is more functional and it works with any language, including Russian, German, Thai, Vietnamese etc. It will make uppercase anything after ' or - or . or ( or ) or space (obviously :).

CREATE FUNCTION [dbo].[fnToProperCase]( @name nvarchar(500) )
RETURNS nvarchar(500)
AS
BEGIN
declare @pos    int = 1
      , @pos2   int

if (@name <> '')--or @name = lower(@name) collate SQL_Latin1_General_CP1_CS_AS or @name = upper(@name) collate SQL_Latin1_General_CP1_CS_AS)
begin
    set @name = lower(rtrim(@name))
    while (1 = 1)
    begin
        set @name = stuff(@name, @pos, 1, upper(substring(@name, @pos, 1)))
        set @pos2 = patindex('%[- ''.)(]%', substring(@name, @pos, 500))
        set @pos += @pos2
        if (isnull(@pos2, 0) = 0 or @pos > len(@name))
            break
    end
end

return @name
END
GO

Answer 7

If you're in SSIS importing data that has mixed cased and need to do a lookup on a column with proper case, you'll notice that the lookup fails where the source is mixed and the lookup source is proper. You'll also notice you can't use the right and left functions is SSIS for SQL Server 2008r2 for derived columns. Here's a solution that works for me:

UPPER(substring(input_column_name,1,1)) + LOWER(substring(input_column_name, 2, len(input_column_name)-1))

Answer 8

On Server Server 2016 and newer, you can use STRING_SPLIT

with t as (
    select 'GOOFYEAR Tire and Rubber Company' as n
    union all
    select 'THE HAPPY BEAR' as n
    union all
    select 'MONK HOUSE SALES' as n
    union all
    select 'FORUM COMMUNICATIONS' as n
)
select
    n,
    (
        select ' ' + (
            upper(left(value, 1))
            + lower(substring(value, 2, 999))
        )
        from (
            select value
            from string_split(t.n, ' ')
        ) as sq
        for xml path ('')
    ) as title_cased
from t

Example

Answer 9

Here is a version that uses a sequence or numbers table rather than a loop. You can modify the WHERE clause to suite your personal rules for when to convert a character to upper case. I have just included a simple set that will upper case any letter that is proceeded by a non-letter with the exception of apostrophes. This does how ever mean that 123apple would have a match on the "a" because "3" is not a letter. If you want just white-space (space, tab, carriage-return, line-feed), you can replace the pattern '[^a-z]' with '[' + Char(32) + Char(9) + Char(13) + Char(10) + ']'.

Answer 10

Borrowed and improved on @Richard Sayakanit answer. This handles multiple words. Like his answer, this doesn't use any UDFs, only built-in functions (STRING_SPLIT and STRING_AGG) and it's pretty fast. STRING_AGG requires SQL Server 2017 but you can always use the STUFF/XML trick. Won't handle every exception but can work great for many requirements.

SELECT StateName = 'North Carolina' 
INTO #States
UNION ALL
SELECT 'Texas'


;WITH cteData AS 
(
    SELECT 
        UPPER(LEFT(value, 1)) +
            LOWER(RIGHT(value, LEN(value) - 1)) value, op.StateName
    FROM   #States op
    CROSS APPLY STRING_SPLIT(op.StateName, ' ') AS ss
)
SELECT 
    STRING_AGG(value, ' ')
FROM cteData c 
GROUP BY StateName

Answer 11

If you know all the data is just a single word here's a solution. First update the column to all lower and then run the following

    update tableName set columnName = 
    upper(SUBSTRING(columnName, 1, 1)) + substring(columnName, 2, len(columnName)) from tableName

Answer 12

A slight modification to @Galwegian's answer - which turns e.g. St Elizabeth's into St Elizabeth'S.

This modification keeps apostrophe-s as lowercase where the s comes at the end of the string provided or the s is followed by a space (and only in those circumstances).

create function properCase(@text as varchar(8000))
returns varchar(8000)
as
begin
    declare @reset int;
    declare @ret varchar(8000);
    declare @i int;
    declare @c char(1);
    declare @d char(1);

    if @text is null
    return null;

    select @reset = 1, @i = 1, @ret = '';

    while (@i <= len(@text))
    select
        @c = substring(@text, @i, 1),
        @d = substring(@text, @i+1, 1),
        @ret = @ret + case when @reset = 1 or (@reset=-1 and @c!='s') or (@reset=-1 and @c='s' and @d!=' ') then upper(@c) else lower(@c) end,
        @reset = case when @c like '[a-za-z]' then 0 when @c='''' then -1 else 1 end,
        @i = @i + 1
    return @ret
end

It turns:

• st elizabeth's into St Elizabeth's
• o'keefe into O'Keefe
• o'sullivan into O'Sullivan

Others' comments that different solutions are preferable for non-English input remain the case.

Answer 13

In Oracle SQL or PostgreSQL, just do:

SELECT INITCAP(title) FROM data;

In SQL Server, define the function first as in below, then:

SELECT dbo.InitCap(title) FROM data;

Define dbo.InitCap():

 -- Drop the function if it already exists
  IF OBJECT_ID('dbo.InitCap') IS NOT NULL
    DROP FUNCTION dbo.InitCap;
  GO
 
 -- Implementing Oracle INITCAP function
 CREATE FUNCTION dbo.InitCap (@inStr VARCHAR(8000))
  RETURNS VARCHAR(8000)
  AS
  BEGIN
    DECLARE @outStr VARCHAR(8000) = LOWER(@inStr),
         @char CHAR(1), 
         @alphanum BIT = 0,
         @len INT = LEN(@inStr),
                 @pos INT = 1;        
 
    -- Iterate through all characters in the input string
    WHILE @pos <= @len BEGIN
 
      -- Get the next character
      SET @char = SUBSTRING(@inStr, @pos, 1);
 
      -- If the position is first, or the previous characater is not alphanumeric
      -- convert the current character to upper case
      IF @pos = 1 OR @alphanum = 0
        SET @outStr = STUFF(@outStr, @pos, 1, UPPER(@char));
 
      SET @pos = @pos + 1;
 
      -- Define if the current character is non-alphanumeric
      IF ASCII(@char) <= 47 OR (ASCII(@char) BETWEEN 58 AND 64) OR
      (ASCII(@char) BETWEEN 91 AND 96) OR (ASCII(@char) BETWEEN 123 AND 126)
      SET @alphanum = 0;
      ELSE
      SET @alphanum = 1;
 
    END
 
   RETURN @outStr;         
  END
  GO

Answer 14

The link I posted above is a great option that addresses the main issue: that we can never programmatically account for all cases (Smith-Jones, von Haussen, John Smith M.D.), at least not in an elegant manner. Tony introduces the concept of an exception / break character to deal with these cases. Anyways, building on Cervo's idea (upper all lower chars preceded by space), the replace statements could be wrapped up in a single table based replace instead. Really, any low/up character combination could be inserted into @alpha and the statement would not change:

declare @str    nvarchar(8000)
declare @alpha  table (low nchar(1), up nchar(1))


set @str = 'ALL UPPER CASE and    SOME lower ÄÄ ÖÖ ÜÜ ÉÉ ØØ ĈĈ ÆÆ'

-- stage the alpha (needs number table)
insert into @alpha
    -- A-Z / a-z
    select      nchar(n+32),
                nchar(n)
    from        dbo.Number
    where       n between 65 and 90 or
                n between 192 and 223

-- append space at start of str
set @str = lower(' ' + @str)

-- upper all lower case chars preceded by space
select  @str = replace(@str, ' ' + low, ' ' + up) 
from    @Alpha

select @str

Answer 15

Recently had to tackle this and came up with the following after nothing quite hit everything I wanted. This will do an entire sentence, cases for special word handling. We also had issues with single character 'words' that a lot of the simpler methods handle but not the more complicated methods. Single return variable, no loops or cursors either.

CREATE FUNCTION ProperCase(@Text AS NVARCHAR(MAX))
RETURNS NVARCHAR(MAX)
AS BEGIN

    DECLARE @return NVARCHAR(MAX)

    SELECT @return = COALESCE(@return + ' ', '') + Word FROM (
         SELECT CASE
            WHEN LOWER(value) = 'llc' THEN UPPER(value)
            WHEN LOWER(value) = 'lp' THEN UPPER(value) --Add as many new special cases as needed
            ELSE
               CASE WHEN LEN(value) = 1
               THEN UPPER(value)
               ELSE UPPER(LEFT(value, 1)) + (LOWER(RIGHT(value, LEN(value) - 1)))
              END
            END AS Word
         FROM STRING_SPLIT(@Text, ' ')
     ) tmp

     RETURN @return
END

It would make sense to maintain a lookup of exceptions to take care of The von Neumann's, McCain's, DeGuzman's, and the Johnson-Smith's.

Here is another variation I found on the SQLTeam.com Forums @ http://www.sqlteam.com/forums/topic.asp?TOPIC_ID=47718

Answer 18

I think you will find that the following is more efficient:

IF OBJECT_ID('dbo.ProperCase') IS NOT NULL
    DROP FUNCTION dbo.ProperCase
GO
CREATE FUNCTION dbo.PROPERCASE (
    @str VARCHAR(8000))
RETURNS VARCHAR(8000)
AS
BEGIN
    SET @str = ' ' + @str
    SET @str = REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE( @str, ' a', ' A'), ' b', ' B'), ' c', ' C'), ' d', ' D'), ' e', ' E'), ' f', ' F'), ' g', ' G'), ' h', ' H'), ' i', ' I'), ' j', ' J'), ' k', ' K'), ' l', ' L'), ' m', ' M'), ' n', ' N'), ' o', ' O'), ' p', ' P'), ' q', ' Q'), ' r', ' R'), ' s', ' S'), ' t', ' T'), ' u', ' U'), ' v', ' V'), ' w', ' W'), ' x', ' X'), ' y', ' Y'), ' z', ' Z')
    RETURN RIGHT(@str, LEN(@str) - 1)
END
GO

The replace statement could be cut and pasted directly into a SQL query. It is ultra ugly, however by replacing @str with the column you are interested in, you will not pay a price for an implicit cursor like you will with the udfs thus posted. I find that even using my UDF it is much more efficient.

Oh and instead of generating the replace statement by hand use this:

-- Code Generator for expression
DECLARE @x  INT,
    @c  CHAR(1),
    @sql    VARCHAR(8000)
SET @x = 0
SET @sql = '@str' -- actual variable/column you want to replace
WHILE @x < 26
BEGIN
    SET @c = CHAR(ASCII('a') + @x)
    SET @sql = 'REPLACE(' + @sql + ', '' ' + @c+  ''', '' ' + UPPER(@c) + ''')'
    SET @x = @x + 1
END
PRINT @sql

Anyway it depends on the number of rows. I wish you could just do s/\b([a-z])/uc $1/, but oh well we work with the tools we have.

NOTE you would have to use this as you would have to use it as....SELECT dbo.ProperCase(LOWER(column)) since the column is in uppercase. It actually works pretty fast on my table of 5,000 entries (not even one second) even with the lower.

In response to the flurry of comments regarding internationalization I present the following implementation that handles every ascii character relying only on SQL Server's Implementation of upper and lower. Remember, the variables we are using here are VARCHAR which means that they can only hold ASCII values. In order to use further international alphabets, you have to use NVARCHAR. The logic would be similar but you would need to use UNICODE and NCHAR in place of ASCII AND CHAR and the replace statement would be much more huge....

-- Code Generator for expression
DECLARE @x  INT,
    @c  CHAR(1),
    @sql    VARCHAR(8000),
    @count  INT
SEt @x = 0
SET @count = 0
SET @sql = '@str' -- actual variable you want to replace
WHILE @x < 256
BEGIN
    SET @c = CHAR(@x)
    -- Only generate replacement expression for characters where upper and lowercase differ
    IF @x = ASCII(LOWER(@c)) AND @x != ASCII(UPPER(@c))
    BEGIN
        SET @sql = 'REPLACE(' + @sql + ', '' ' + @c+  ''', '' ' + UPPER(@c) + ''')'
        SET @count = @count + 1
    END
    SET @x = @x + 1
END
PRINT @sql
PRINT 'Total characters substituted: ' + CONVERT(VARCHAR(255), @count)

Basically the premise of the my method is trading pre-computing for efficiency. The full ASCII implementation is as follows:

IF OBJECT_ID('dbo.ProperCase') IS NOT NULL
    DROP FUNCTION dbo.ProperCase
GO
CREATE FUNCTION dbo.PROPERCASE (
    @str VARCHAR(8000))
RETURNS VARCHAR(8000)
AS
BEGIN
    SET @str = ' ' + @str
SET @str =     REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(@str, ' a', ' A'), ' b', ' B'), ' c', ' C'), ' d', ' D'), ' e', ' E'), ' f', ' F'), ' g', ' G'), ' h', ' H'), ' i', ' I'), ' j', ' J'), ' k', ' K'), ' l', ' L'), ' m', ' M'), ' n', ' N'), ' o', ' O'), ' p', ' P'), ' q', ' Q'), ' r', ' R'), ' s', ' S'), ' t', ' T'), ' u', ' U'), ' v', ' V'), ' w', ' W'), ' x', ' X'), ' y', ' Y'), ' z', ' Z'), ' š', ' Š'), ' œ', ' Œ'), ' ž', ' Ž'), ' à', ' À'), ' á', ' Á'), ' â', ' Â'), ' ã', ' Ã'), ' ä', ' Ä'), ' å', ' Å'), ' æ', ' Æ'), ' ç', ' Ç'), ' è', ' È'), ' é', ' É'), ' ê', ' Ê'), ' ë', ' Ë'), ' ì', ' Ì'), ' í', ' Í'), ' î', ' Î'), ' ï', ' Ï'), ' ð', ' Ð'), ' ñ', ' Ñ'), ' ò', ' Ò'), ' ó', ' Ó'), ' ô', ' Ô'), ' õ', ' Õ'), ' ö', ' Ö'), ' ø', ' Ø'), ' ù', ' Ù'), ' ú', ' Ú'), ' û', ' Û'), ' ü', ' Ü'), ' ý', ' Ý'), ' þ', ' Þ'), ' ÿ', ' Ÿ')
    RETURN RIGHT(@str, LEN(@str) - 1)
END

Answer 19

Is it too late to go back and get the un-uppercased data?

The von Neumann's, McCain's, DeGuzman's, and the Johnson-Smith's of your client base may not like the result of your processing...

Also, I'm guessing that this is intended to be a one-time upgrade of the data? It might be easier to export, filter/modify, and re-import the corrected names into the db, and then you can use non-SQL approaches to name fixing...

Just learned about InitCap().

Here is some sample code:

      ,InitCap(LastName ||', '|| FirstName ||' '|| Nvl(MiddleName,'')) AS RecipientName
FROM SomeTable

Answer 21

This worked in SSMS:

Select Jobtitle,
concat(Upper(LEFT(jobtitle,1)), SUBSTRING(jobtitle,2,LEN(jobtitle))) as Propercase
From [HumanResources].[Employee]

Answer 22

Sadly, I am proposing yet another function. This one seems faster than most, but only capitalizes the first letter of words separated by spaces. I've checked that the input is not null, and that it works if you have multiple spaces somewhere in the middle of the string. I'm cross applying the length function so I don't have to call it twice. I would have thought that SQL Server would have cached that value. Caveat emptor.

CREATE OR ALTER FUNCTION dbo.ProperCase(@value varchar(MAX)) RETURNS varchar(MAX) AS  
 BEGIN
 
     RETURN (SELECT STRING_AGG(CASE lv WHEN 0 THEN '' WHEN 1 THEN UPPER(value) 
      ELSE UPPER(LEFT(value,1)) + LOWER(RIGHT(value,lv-1)) END,' ')  
     FROM STRING_SPLIT(TRIM(@value),' ') AS ss 
      CROSS APPLY (SELECT LEN(VALUE) lv) AS reuse 
     WHERE @value IS NOT NULL)

 END

This function has worked for me

create function [dbo].Pascal (@string varchar(max))
returns varchar(max)
as
begin
    declare @Index int
        ,@ResultString varchar(max)

    set @Index = 1
    set @ResultString = ''

    while (@Index < LEN(@string) + 1)
    begin
        if (@Index = 1)
        begin
            set @ResultString += UPPER(SUBSTRING(@string, @Index, 1))
            set @Index += 1
        end
        else if (
                (
                    SUBSTRING(@string, @Index - 1, 1) = ' '
                    or SUBSTRING(@string, @Index - 1, 1) = '-'
                    or SUBSTRING(@string, @Index + 1, 1) = '-'
                    )
                and @Index + 1 <> LEN(@string) + 1
                )
        begin
            set @ResultString += UPPER(SUBSTRING(@string, @Index, 1))
            set @Index += 1
        end
        else
        begin
            set @ResultString += LOWER(SUBSTRING(@string, @Index, 1))
            set @Index += 1
        end
    end

    if (@@ERROR <> 0)
    begin
        set @ResultString = @string
    end

    return replace(replace(replace(@ResultString, ' ii', ' II'), ' iii', ' III'), ' iv', ' IV')
end

Answer 24

I know the devil is in the detail (especially where people's personal data is concerned), and that it would be very nice to have properly capitalised names, but the above kind of hassle is why the pragmatic, time-conscious amongst us use the following:

SELECT UPPER('Put YoUR O'So oddLy casED McWeird-nAme von rightHERE here')

In my experience, people are fine seeing THEIR NAME ... even when it's half way through a sentence.

Copy and paste your data into MS Word and use built in text-conversion to "Capitalize Each Word". Compare against your original data to address exceptions. Can't see any way around manually sidestepping "MacDonald" and "IBM" type exceptions but this was how I got it done FWIW.
