Solution

DECLARE @T TABLE
(
ID  INT PRIMARY KEY,
CITTA   VARCHAR(50)
)
INSERT INTO @T
SELECT 1, 'ABANO TERME' UNION ALL SELECT 2, 'ROMA' UNION ALL SELECT 3, 'ISOLA D''ASTI';

IF OBJECT_ID('tempdb..#HolderTable') IS NOT NULL
    DROP TABLE #HolderTable

CREATE TABLE #HolderTable
(
Idx INT IDENTITY(1,1) PRIMARY KEY,
ID INT,
Word  VARCHAR(50)
)

CREATE NONCLUSTERED INDEX ix ON #HolderTable(ID)
;

WITH T1 AS
(
SELECT ID, CAST(N'<root><r>' + REPLACE(REPLACE(CITTA, '''', '''</r><r>'), ' ', ' </r><r>') + '</r></root>' AS XML) AS xl
FROM @T
)
INSERT INTO #HolderTable
SELECT ID, 
       r.value('.','NVARCHAR(MAX)') AS Item
 FROM T1
 CROSS APPLY
xl.nodes('//root/r') AS RECORDS(r)

SELECT 
      ID, 
      (SELECT STUFF(LOWER(Word),1,1,UPPER(LEFT(Word,1))) FROM #HolderTable WHERE [@T].ID =  #HolderTable.ID ORDER BY Idx FOR XML PATH('') )
FROM @T [@T]

Problem

Is it possible to convert text from a table column in SQL Server to PascalCase only using a proper SQL code? ``` TABLE DEFINITION ---------------------- ID int CITTA varchar(50) PROV varchar(50) CAP varchar(50) COD varchar(50) ``` The field that contains text to convert is `CITTA`. It contains all uppercase values like "ABANO TERME", "ROMA", and so on. The words are delimited by a space. EDIT I forgot to mention that some words have an accent character in it `'`. This character can be found either at the end of the word or in the middle. EDIT 2: Some quirks found on results: - If I have a name like "ISOLA BALBA" this name get translated to "IsolaBalba" (correct case but missed space) - If I have a name like "ISOLA D'ASTI" this get converted to "IsolaD'asti" (missed space as before and incorrect case. In this case the correct result is "Isola D'Asti" could you please give me some advice on this small problem?
