With a little help of a split function like <a href="https://stackoverflow.com/a/314917/569436">this one</a>.

Try this, replace <code>YourTable</code> with whatever your table name is:

<pre><code>update T
set Name = P.Name
from YourTable as T
 cross apply (select (select upper(left(X.s, 1))+lower(stuff(X.s, 1, 1, ''))+' '
 from dbo.split(' ', Name) as X
 for xml path(''), type).value('.', 'varchar(50)')

SQL Server Don't have <code>Initcap</code> function like oracle.

You can create UDF for Initcap.

<pre><code>CREATE FUNCTION [dbo].[InitCap] ( @InputString varchar(4000) ) 
RETURNS VARCHAR(4000)
AS
BEGIN

DECLARE @Index INT
DECLARE @Char CHAR(1)
DECLARE @PrevChar CHAR(1)
DECLARE @OutputString VARCHAR(255)

SET @OutputString = LOWER(@InputString)
SET @Index = 1

WHILE @Index &lt;= LEN(@InputString)
BEGIN
 SET @Char = SUBSTRING(@InputString, @Index, 1)
 SET @PrevChar = CASE WHEN @Index = 1 THEN ' '
 ELSE SUBSTRING(@InputString, @Index - 1, 1)
 END

 IF @PrevChar IN (' ', ';', ':', '!', '?', ',', '.', '_', '-', '/', '&amp;', '''', '(')
 BEGIN
 IF @PrevChar != '''' OR UPPER(@Char) != 'S'
 SET @OutputString = STUFF(@OutputString, @Index, 1, UPPER(@Char))
 END

 SET @Index = @Index + 1
END

RETURN @OutputString

END
GO
</code></pre>

Checking for UDF working

<pre><code>select [dbo].[InitCap] ('stackoverflow com');

Stackoverflow Com
</code></pre>

you can update your table like this

<pre><code>update table
set column=[dbo].[InitCap](column);
</code></pre>

I have a table on my database. My table's name is "Company". I want to change data "company_name" as upper case first letter. For example;

"ABC COMPANY"

"DEF PLASTICITY"

as

"Abc Company"

"Def Plasticity"

I know that I should use "UPDATE" command. But How? Thanks for your help!
