SQL Server Convert String to Proper Case (Camel Case) or Title Case Function Example

Sep 8, 2015
Introduction:

Here I will explain how to convert string to proper case or title case or camel case in
sql server with example. To convert string to proper case or title case in sql server we don’t have any built in function for that we need to create user defined functions to convert string to title case in sql server.
Description:

To call stored procedure from another stored procedure with parameters in sql server follow below steps

Create New Function fn_titlecase in database


create function fn_titlecase(@str as varchar(1000))
returns varchar(1000)
as
begin
declare @bitval bit;
declare @result varchar(1000);
declare @i int;
declare @j char(1);
select @bitval = 1, @i=1, @result = '';
while (@i <= len(@str))
select @j= substring(@str,@i,1),
@result = @result + case when @bitval=1 then UPPER(@j) else LOWER(@j) end,
@bitval = case when @j like '[a-zA-Z]' then 0 else 1 end,
@i = @i +1
return @result
end

Once you create function in database execute following query it will return data string in title case or proper case or camel case in sql server.


-- Execute this query to convert string to title case / proper case in sql server
select dbo.fn_titlecase('hi, welcome to aspdotnet-suresh.com')

If we execute above query we will get output like as shown below
