SELECT RIGHT(@bigOne, 6)

Returns the right part of a character string with the specified number of characters.
Here is the MSDN for the <code>Right()</code> function as well: 
<a href="http://msdn.microsoft.com/en-us/library/ms177532.aspx">http://msdn.microsoft.com/en-us/library/ms177532.aspx</a>

In your case corey you can do: 

<code>SELECT RIGHT(num, 6) FROM db WHERE user=@user</code>

Just replace <code>num</code> with the name of your column from your database table, and change <code>db</code> to the name of your table that you are <code>SELECT</code>ing from.

This will accurately get the last 6 digits from the argument you pass.

One thing to note. In SQL Server 2005, the "\" (backslash) character does not return 1 by ISNUMERIC. But it does in SQL Server 2008. This function should work in both versions of SQL Server since we're simply excluding this character in the 7th piece of my test argument above.

PRINT RIGHT(dbo.fnNumericDigits('5-555-555551-2345-6-'), 6) 

Scalar-valued Function:

<pre><code>ALTER FUNCTION [dbo].[fnNumericDigits]
(
 @startString NVARCHAR(255)
) RETURNS NVARCHAR(255)
AS
BEGIN

 DECLARE @returnString NVARCHAR(255)
 DECLARE @length INT, @currentDigit INT, @currentCharacter NVARCHAR(1)
 SELECT @length = LEN(@startString), @currentDigit = 1, @returnString = ''

 WHILE @currentDigit &lt;= @length
 BEGIN

 SELECT @currentCharacter = SUBSTRING(@startString, @currentDigit, @currentDigit)

 IF ISNUMERIC(@currentCharacter) = 1 
 AND @currentCharacter != '$'
 AND @currentCharacter != '+'
 AND @currentCharacter != ','
 AND @currentCharacter != '-'
 AND @currentCharacter != '.'
 AND @currentCharacter != '\'
 BEGIN
 SELECT @returnString = @returnString + @currentCharacter

 SELECT @currentDigit = @currentDigit + 1

END

RETURN @returnString

I have a data field in a SQL table with a large number (9 digits, A Customer Information Number). I want to run a stored procedure that will only SELECT the last 6 digits of the number. 

Something like:

<pre><code>SELECT (Last 6 Digits of num) FROM db
WHERE user = @user
</code></pre>

Does anyone know of a way to accomplish this?

Stored Procedure to SELECT Last 6 Digits of Number

我在一个SQL表中有一个数据字段，其中包含一个很大的数字(9位数字，一个客户信息号)。我想运行一个只选择数字的最后6位的存储过程。类似于：SELECT (Last 6 Digits of num) FROM dbWHERE user = @user有没有人知道有什么方法可以做到这一点？
