Need help converting 2 columns to proper case in SQL Server 2005.

I have 2 columns in an SQL database table, LastName, and FirstName. The information entered is all mixed case. I have i.e. JOHN SMITH,  jane doe, John Doe. Is there any way for me to run a query on  those 2 columns and correct the case to proper case? I would also like to create a backup plan, like copy this table and rename it, just in case the original table gets toasted accidentally.

Hi,

here you can find a user defined function to Propercase a string:

http://pscode.com/vb/scripts/ShowCode.asp?txtCodeId=780&lngWId=5

you can use it in this form

update myTable set LastName = fn_PROPERCASE_All(LastName), firstName = fn_PROPERCASE_All(FirstName).

To make a backup of your tables, you can do

SELECT * INTO myTable_backup
FROM myTable

this will create the table myTable_backup and copy all the data there.

Hope this helps.

You could create a function like
ALTER FUNCTION ProperCase
        (@text varchar(256))
RETURNS varchar(256)
AS

BEGIN
declare @counter int,
      @newtext varchar(256)
SET @counter = 2
SET @text = ltrim(rtrim(@text))
set @newtext = UPPER(SUBSTRING(@text,1,1))

WHILE @counter <= len(@text)
        BEGIN
                  IF SUBSTRING(@text,@counter - 1,1) = ' '
                        OR SUBSTRING(@text,@counter - 2,2) = 'mc'
                        OR SUBSTRING(@text,@counter - 2,2) = ' o'
                        SET @newtext = @newtext + UPPER(SUBSTRING(@text, @counter,1))
                  ELSE
                        SET @newtext = @newtext + LOWER(SUBSTRING(@text, @counter,1))
                  SET @counter = @counter + 1
        END
finish:
RETURN @newtext
END

"Proper Case" can vary.  If it is for names is hard to get it exactly right (names like terHorst, Van de Graff, de la Garza... )  And titles have rules for words that are always lower case.  You can modify the function to include the rules you want.

Once you have a function that suits your needs you can test it like:

SELECT FirstName, LastName, dbo.ProperCase(FirstName), dbo.ProperCase(LastName)
FROM YourTable

Then backup the table with:
SELECT *
INTO YourTableBackup
FROM YourTable

Then update with
UPDATE YourTable
SET FirstName = dbo.ProperCase(FirstName),
    LastName =  dbo.ProperCase(LastName)
