I am an Oracle PL/SQL guy but have hit an issue in trying to get this function converted to SQL Server.

The TO_CHAR piece of this doesn't exist (among other things).

Can someone please help me convert this?

Thanks in advance!

CREATE OR REPLACE FUNCTION format_sequence (p_number IN INTEGER)
    RETURN VARCHAR2
IS
    v_num   INTEGER := FLOOR (p_number / 1000);
BEGIN
    RETURN    CHR (FLOOR (v_num / (26 * 26)) + 65)
           || CHR (FLOOR (MOD (v_num, 26 * 26) / 26) + 65)
           || CHR (MOD (v_num, 26) + 65)
           || TO_CHAR (MOD (p_number, 1000), 'fm000');
END;

The function is here:
USE [Expres]
GO
/****** Object:  UserDefinedFunction [dbo].[format_sequence]    Script Date: 05/14/2009 20:53:12 ******/
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
-- =============================================
-- Author:		<Author,,Name>
-- Create date: <Create Date, ,>
-- Description:	<Description, ,>
-- =============================================
CREATE FUNCTION [dbo].[format_sequence] 
(
	-- Add the parameters for the function here
	@p_number int
)
RETURNS varchar(6)
AS
BEGIN
	-- Declare the return variable here
	DECLARE @ResultVar varchar(6)
	DECLARE @v_num int
	
	SET @v_num = FLOOR (@p_number / 1000)
 
    SET @ResultVar = CHAR (FLOOR (@v_num / (26 * 26)) + 65)
           + CHAR (FLOOR ((@v_num % (26 * 26)) / 26) + 65)
           + CHAR (@v_num % 26 + 65)
           + REPLACE(STR (@p_number % 1000, 3, 0),' ','0')
 
	-- Return the result of the function
	RETURN @ResultVar
 
END

The
USE [Expres]
GO
at the beginning should be replaced by your database name.

If you'll modify this function, you have to change
CREATE FUNCTION
to
ALTER FUNCTION

I have already done that (so different than Oracle) but thank you so much!
