LPAD in SQL Server 2008

I can't see a function like LPAD in SQL Server 2008. For example how can I convert the following queries into T-SQL?

select  LPAD(MY_VALUE,2,' ')) VALUE
FROM MY_TABLE

Solution 1:

Basically pad it with the number of characters you are intending to select and then right the string.

Select right(replicate(' ',2) + YourFieldValue,2) from YourTable

You can use the space function instead of replicate, space(number_of_spaces), replicate just allows you to pad with alternative characters.

Solution 2:

Manual calculations can be annoying to apply inside queries. Luckily, we can create a function:

CREATE FUNCTION LPAD
(
    @string VARCHAR(MAX), -- Initial string
    @length INT,          -- Size of final string
    @pad CHAR             -- Pad character
)
RETURNS VARCHAR(MAX)
AS
BEGIN
    RETURN REPLICATE(@pad, @length - LEN(@string)) + @string;
END
GO

(Please replace VARCHAR with NVARCHAR to your liking, or use an alternative algorithm.)

Then:

SELECT dbo.LPAD(MY_VALUE, 2, ' ') VALUE
FROM MY_TABLE

Should work since SQL Server 2005.
