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.
