Proper Case Problem

  • Hi,

    I've created a function that will set column values into Proper case.Say for example:

    FROM this format:

    AA BB

    To this format:

    Aa Bb

    My problem is,how can I set/change the values ending with roman numeral? Like,

    FROM this format:

    AA BB II or AA BB III

    TO this format:

    Aa Bb II or Aa Bb III

    Function script:

    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);

    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

  • i needed to play with data.

    Declare @tbl table ( main_text nvarchar(200), Without_Roman_values nvarchar(100),Roman_values nvarchar(50) )

    insert into @tbl (main_text)

    select 'BHUVH III'

    union

    SELECT 'DEXY V'

    UNION

    SELECT 'JACK TONY VIII'

    update @tbl

    set Without_Roman_values = reverse(substring(reverse(main_text),charindex(' ', reverse(main_text) ,1), LEN(main_text))),

    Roman_values = reverse(substring(reverse(main_text), 1, charindex(' ', reverse(main_text) ,1)))

    select *,(dbo.ProperCase(Without_Roman_values)+ roman_values )as OutPut from @tbl

  • Great idea, Bhuvnesh, but that won't work when there are no Roman numerals at the end.

    JOHN JONES will end up as John JONES.

    But you could use your idea to strip off that last 'word' from the end of a name and match it against a table or list of possible values ('I','II','III','IV','V','VI', etc) and only leave it intact if it matches.

    yes i had same doubt but couldnt think as u did. i am gree with you that we can do some lookup table comparision for ROMAN values.

  • It might be a better plan to either store the parts of the names separately (e.g. prefix, suffix) or to do this sort of presentation work on the application responsible for generating the input in the first place. Formatting is rarely best done inside the database.

  • I am with Paul on this one - store each piece of the name in it's own field (even though this leaves a lot of empty fields for the suffix). Even with that scheme though you still run into McAfee, McDonald, D'Angelo.... proper case is a long standing tough problem.

    Edit: I should have googled before posting. Here are just a few links that turn up. As you can see, it's not easy and is a thorn in the sides of many.

  • One other idea is to embed the formatting rules in a .NET function. The same function could be used in the application or the database using SQLCLR integration. Just another option.
