Format Date in SQL Server

It’s very common to show the current date (i.e., month, day, and year) in different formats. Although you can obtain the current date with Microsoft SQL Server’s GETDATE function, getting the returned date in the format you need can take a lot of effort and code.

Quickie – Concatenate Rows as a String

Today I needed to concatenate a field from multiple rows in SQL Server to get a list of people names. Instead of doing it in code, you can use the following syntax:

DECLARE @Names VARCHAR(8000)
SELECT @name = ”
SELECT @Names = @Names + ‘,’ + Names FROM People
SELECT SUBSTRING(2, @Names, 7998)

Happy Concatenating!!

Order BY Not Working in SQL Server Functions | Quickie

Ever created a function and needed to include the Order By clause. It would result in the following error being loaded:

The ORDER BY clause is invalid in views, inline functions, derived tables, subqueries, and common table expressions, unless TOP or FOR XML is also specified.

The problem is that to use, it requires a TOP clause or FOR XML. By if you specify TOP 100, you’ll only get the first 100 rows. You can specify a big number that you might think will never exceed. But what if you do? The best bet is to use TOP 100 PERCENT.

This will get you all the rows and works in Functions.

ASP.Net | Read Values from Javascript

Today I started checking out some videos about Windows CardSpace and ASP.Net for logging in and I saw how he used javascript to get client side input and use it in ASP.Net in the C# code.

First you need to create a HiddenField on your webForm and name it TokenField (any name would actually do)

<asp:HiddenField ID=”TokenField” runat=”server” />

To set the Hidden Field value in JavaScript use the following code: Continue reading »

SQL Server 2005 | Add days, months and years to GetDate()

SQL Server | Remove Special Characters

I needed to remove all the special characters from a field in a particular table in SQL Server to be used for searching purposes. After searching (binging )… I found the next SQL Server Function which did the trick.

This Function Removes any special character from the string value passed. All characters except 0-9, a-z and A-Z are all removed, whilst the remaining characters are returned back.

ALTER FUNCTION dbo.RemoveSpecialCharacters
(
@s VARCHAR(256)
)
RETURNS VARCHAR(256) WITH SCHEMABINDING

BEGIN
IF (@s is null)
RETURN null Continue reading »
