I need to convert a value 5.300000000 to 0005300. Basically I want to remove the decimal point, pad the out put with a couple of zeros and return a value that is 7 bytes long. I may need to convert something like 10.300000000 to be 0010300.
Anyone have any thoughts?
Thanks.DECLARE @.x decimal(5,2)
SELECT @.x = 5.3
SELECT @.x, RIGHT(REPLICATE('0',7)+REPLACE(CONVERT(varchar(7), @.x * 10),'.',''),7)|||Hi,
Here is a little code that should do it for you.
Granted it is ugly but it works
declare @.d decimal (16,9)
set @.d = 9.3000
print Replicate('0', 7 - len ( replace( Left(@.d,Charindex('.',Cast(@.d as Varchar))+3),'.','')))+ replace(Left(@.d,Charindex('.',Cast(@.d as varchar))+3),'.','')
Hope that Helps
Tal McMahon|||I have a function for zero-padding, which cleans things up a bit in my queries:
CREATE FUNCTION [dbo].[fn_zero_pad]
(@.string_data VARCHAR(100),
@.new_length INT)
RETURNS VARCHAR(100) AS
BEGIN
RETURN REPLICATE('0', @.new_length - LEN(@.string_data)) + @.string_data
END

Convert to Number IF it is a number
Pardon my newbieness:
I have a column that could contain numbers or text (not my idea). All
of the values are returned as text. I want to return the value as a
number if it is a number, otherwise (of course) leave it as text. What
can I do?Return the value to where?
A single column in a resultset has exactly one datatype.
Can't your receiving application or front end code figure out what kind of
data it is?
Why are you storing numbers and strings in the same column?

Use the ISNUMERIC function. Check the syntax in Books OnLine.

A column only has a single datatype so I'm going to assume you require a
result set with two columns: one VARCHAR, one INTEGER. I will also assume
that when you say "text" you really mean "VARCHAR". Doing this using the
TEXT datatype would be a bit more tricky. That's too many assumptions but if
you don't post a more precise spec then assumptions and guesses are what you
will get. You can help us to help you better by taking the advice in the
following article:
http://www.aspfaq.com/etiquette.asp?id=5006
Here's my example:
CREATE TABLE tbl (x VARCHAR(10) PRIMARY KEY) ;
INSERT INTO tbl (x)
SELECT '123' UNION ALL
SELECT '99A' UNION ALL
SELECT 'ABC' ;
SELECT x, CAST(num AS INTEGER) AS num
FROM
(SELECT x,
CASE WHEN x NOT LIKE '%[^0-9]%' THEN x END AS num
FROM tbl) AS T ;
Result:
x num
-- --
123 123
99A NULL
ABC NULL
(3 row(s) affected)
Hope this helps.
